Obesity

Overweight boy, infertile man?

When it comes to causes of infertility, history and science have generally focused on women. A lot of the research overlooks men, but some previous studies have suggested that male infertility contributes to about half of the cases of couple infertility. The reason for much of that male infertility, however, has been a mystery. Until now.

A group of Italian investigators looked at the declining trend in sperm counts over the past 40 years and the increase of childhood obesity. Is there a correlation? The researchers think so. Childhood obesity can be linked to multiple causes, but the researchers zeroed in on the effect that obesity has on metabolic rates and, therefore, testicular growth.

Collecting data on testicular volume, body mass index (BMI), and insulin resistance from 268 boys aged 2-18 years, the researchers discovered that those with normal weight and normal insulin levels had testicular volumes 1.5 times higher than their overweight counterparts and 1.5-2 times higher than those with hyperinsulinemia, building a case for obesity being a factor for infertility later in life.

Since low testicular volume is associated with lower sperm count and production as an adult, putting two and two together makes a compelling argument for childhood obesity being a major male infertility culprit. It also creates even more urgency for the health care industry and community decision makers to focus on childhood obesity.

It sure would be nice to be able to take one of the many risk factors for future human survival off the table. Maybe by taking something, like cake, off the table.

Fecal transplantation moves to the kitchen

Fecal microbiota transplantation is an effective way to treat Clostridioides difficile infection, but, in the end, it’s still a transplantation procedure involving a nasogastric or colorectal tube or rather large oral capsules with a demanding (30-40 capsules over 2 days) dosage. Please, Science, tell us there’s a better way.

Science, in the form of investigators at the University of Geneva and Lausanne University Hospital in Switzerland, has spoken, and there may be a better way. Presenting fecal beads: All the bacterial goodness of donor stool without the tubal insertions or massive quantities of giant capsules.

We know you’re scoffing out there, but it’s true. All you need is a little alginate, which is a “biocompatible polysaccharide isolated from brown algae” of the Phaeophyceae family. The donor feces is microencapsulated by mixing it with the alginate, dropping that mixture into water containing calcium chloride, turning it into a gel, and then freeze-drying the gel into small (just 2 mm), solid beads.

Sounds plausible enough, but what do you do with them? “These brownish beads can be easily dispersed in a liquid or food that is pleasant to eat. They also have no taste,” senior author Eric Allémann, PhD, said in a statement released by the University of Geneva.

Pleasant to eat? No taste? So which is it? If you really want to know, watch fecal beads week on the new season of “The Great British Baking Show,” when Paul and Prue judge poop baked into crumpets, crepes, and crostatas. Yum.
 

We’re on the low-oxygen diet

Nine out of ten doctors agree: Oxygen is more important to your continued well-being than food. After all, a human can go weeks without food, but just minutes without oxygen. However, ten out of ten doctors agree that the United States has an obesity problem. They all also agree that previous research has shown soldiers who train at high altitudes lose more weight than those training at lower altitudes.

PBRC

So, on the one hand, we have a country full of overweight people, and on the other, we have low oxygen levels causing weight loss. The solution, then, is obvious: Stop breathing.

More specifically (and somewhat less facetiously), researchers from Louisiana have launched the Low Oxygen and Weight Status trial and are currently recruiting individuals with BMIs of 30-40 to, uh, suffocate themselves. No, no, it’s okay, it’s just when they’re sleeping.

Fine, straight face. Participants in the LOWS trial will undergo an 8-week period when they will consume a controlled weight-loss diet and spend their nights in a hypoxic sealed tent, where they will sleep in an environment with an oxygen level equivalent to 8,500 feet above sea level (roughly equivalent to Aspen, Colo.). They will be compared with people on the same diet who sleep in a normal, sea-level oxygen environment.

The study’s goal is to determine whether or not spending time in a low-oxygen environment will suppress appetite, increase energy expenditure, and improve weight loss and insulin sensitivity. Excessive weight loss in high-altitude environments isn’t a good thing for soldiers – they kind of need their muscles and body weight to do the whole soldiering thing – but it could be great for people struggling to lose those last few pounds. And it also may prove LOTME’s previous thesis: Air is not good.

SEATTLE – The American Association of Clinical Endocrinology (AACE) has released a new consensus statement aimed at helping clinicians reduce stigma and bias around obesity.

Highlights from the statement, entitled “Addressing stigma and bias in the diagnosis and management of patients with obesity/adiposity-based chronic disease and assessing bias and stigmatization as determinants of disease severity,” were presented at the annual scientific & clinical congress of the American Association of Clinical Endocrinology. It will be published later this year in Endocrine Practice.

The document reiterates AACE’s previous proposal to use the term “adiposity-based chronic disease (ABCD)” to refer to the spectrum of complications of obesity beyond weight. AACE has incorporated weight bias, stigmatization, psychological health, and social determinants of health into disease staging based on the degree to which these factors impair quality of life and could negatively affect treatment. Another change is the use of a scale from 1 to 3 for ABCD staging, in contrast to the previous scale from 0 to 3, as follows.

Stage 1 (previously 0): No known physical ABCD complications (for example, cardiovascular, biomechanical) but with increased risk that might be reduced by weight loss, and/or internalized weight bias and stigmatization, psychological conditions, and social determinants of health that don’t have immediate adverse health effects but may require individualized care.

Stage 2 (previously 1): One or more mild-moderate ABCD complications plus increased risk of other complications and/or bias/stigma/social determinants that adversely affect quality of life or could impair ABCD treatment.

Stage 3 (previously 2): At least one severe ABCD complication plus increased risk for others, and/or bias/stigma/social determinants with pronounced adverse effects on quality of life or that interfere with weight loss treatment plans or render them harmful.

To accomplish this staging, clinicians are advised to use validated questionnaires to screen patients for the presence and degree of self-stigmatization and internalized weight bias and to refer patients to mental health professionals for related psychological issues. The document also advises clinicians to implement practice policies such as implicit bias training and obesity education for their staff.  

“I really hope that this document will increase awareness of the vicious cycle of weight bias, stigma, and internalized weight bias for patients with obesity, both on an individual basis and a bigger chronic care model basis ... By utilizing these concepts in the document, we hope to at least take steps towards reducing the stigma and internalized weight bias and slowing down or reversing that vicious cycle to better care for people with a focus on their health ... It’s not just about a person’s weight,” Karl Nadolsky, DO, the statement’s co-lead author, said.

The new statement builds on previous AACE efforts, including the 2014 publication entitled, “Advanced framework for a new diagnosis of obesity as a chronic disease,” the 2016 management guidelines, and the 2016 position statement, which introduced the ABCD term. All are meant to advance the concept of obesity or ABCD as a medical condition, rather than a cosmetic problem or lifestyle choice.

Now, AACE is explicitly calling attention to the integral role of internal and external weight bias and stigma as both drivers and complications of the condition. The AACE writing panel adopted some of the concepts from a 2020 international consensus statement focusing on obesity stigma, Dr. Nadolsky said.

“We need to focus on health, the biopsychosocial mode. We have to think about the person as a whole. The disease of obesity is really a quintessential disease state that needs a very good holistic approach,” he said.

Asked to comment, Yoni Freedhoff, MD, associate professor, department of family medicine, University of Ottawa, and Medical Director of the Bariatric Medical Institute, said: “I do think staging/categorization are important in the context of bias and stigma and also to combat the notion that the goal is simple medicalization ... It’s good to see the consideration of internalized weight bias as part of an effort to understand the impact of obesity on an individual.”

However, Dr. Freedhoff said he would have preferred that the implicit and internalized bias concepts had been incorporated into the 2009 Edmonton Obesity Staging System, which he believes is easier to use than the AACE staging system.

Dr. Freedhoff also disagrees that it was necessary to remove “0” from the staging (still present in the Edmonton system), done by AACE out of concern that people might mistakenly think it implies zero risk. “It just means no current objective or subjective impact of weight on health or quality of life,” he said.

But, Dr. Nadolsky noted that data on people with “metabolically healthy obesity” suggest that “they might have zero complications but they’re still at high risk, from cancer to stigma and bias, which are a cause of and consequence of obesity and should be part of the ABCD staging system.”

Indeed, Dr. Freedhoff noted, “Obesity confers risk. Just like hypertension. And just like with hypertension, risk is not a guarantee of problems. But we still discuss treatment and people can be symptom- or problem-free when we start it. It can also be ‘borderline’ or mild. But no one gets upset about the idea of treating a known risk factor, or diagnosing a known risk factor, when minor, and when it’s not had any impact on a person’s health. That we don’t do same with obesity is consequent to bias.”

In addition to influencing health care providers and health care systems, the statement also concludes: “Society, including payers and policymakers, should support policies, education, research, and access to care to limit bias and stigma faced by individuals with obesity/ABCD.”

Dr. Nadolsky has reported no relevant financial relationships. Dr. Freedhoff has reported working with the Bariatric Medical Institute and Constant Health, which has received a research grant from Novo Nordisk.

Communities with easy access to fast food were 77% more likely to have high levels of obesity-related cancer mortality, based on data from a new cross-sectional study of more than 3,000 communities.

Although increased healthy eating has been associated with reduced risk of obesity and with reduced cancer incidence and mortality, access to healthier eating remains a challenge in communities with less access to grocery stores and healthy food options (food deserts) and/or easy access to convenience stores and fast food (food swamps), Malcolm Seth Bevel, PhD, of the Medical College of Georgia, Augusta, and colleagues, wrote in their paper, published in JAMA Oncology.

In addition, data on the association between food deserts and swamps and obesity-related cancer mortality are limited, they said.

“We felt that the study was important given the fact that obesity is an epidemic in the United States, and multiple factors contribute to obesity, especially adverse food environments,” Dr. Bevel said in an interview. “Also, I lived in these areas my whole life, and saw how it affected underserved populations. There was a story that needed to be told, so we’re telling it,” he said in an interview.

In a study, the researchers analyzed food access and cancer mortality data from 3,038 counties across the United States. The food access data came from the U.S. Department of Agriculture Food Environment Atlas (FEA) for the years 2012, 2014, 2015, 2017, and 2020. Data on obesity-related cancer mortality came from the Centers for Disease Control and Prevention for the years from 2010 to 2020.

Food desert scores were calculated through data from the FEA, and food swamp scores were based on the ratio of fast-food restaurants and convenience stores to grocery stores and farmers markets in a modification of the Retail Food Environment Index score.

The researchers used an age-adjusted, multiple regression model to determine the association between food desert and food swamp scores and obesity-related cancer mortality rates. Higher food swamp and food desert scores (defined as 20.0 to 58.0 or higher) were used to classify counties as having fewer healthy food resources. The primary outcome was obesity-related cancer mortality, defined as high or low (71.8 or higher per 100,000 individuals and less than 71.8 per 100,000 individuals, respectively).

Overall, high rates of obesity-related cancer mortality were 77% more likely in the counties that met the criteria for high food swamp scores (adjusted odds ratio 1.77). In addition, researchers found a positive dose-response relationship among three levels of both food desert scores and food swamp scores and obesity-related cancer mortality.

A total of 758 counties had obesity-related cancer mortality rates in the highest quartile. Compared to counties with low rates of obesity-related cancer mortality, counties with high rates of obesity-related cancer mortality also had a higher percentage of non-Hispanic Black residents (3.26% vs. 1.77%), higher percentage of adults older than 65 years (15.71% vs. 15.40%), higher rates of adult obesity (33.0% vs. 32.10%), and higher rates of adult diabetes (12.50% vs. 10.70%).

Possible explanations for the results include the lack of interest in grocery stores in neighborhoods with a population with a lower socioeconomic status, which can create a food desert, the researchers wrote in their discussion. “Coupled with the increasing growth rate of fast-food restaurants in recent years and the intentional advertisement of unhealthy foods in urban neighborhoods with [people of lower income], the food desert may transform into a food swamp,” they said.

The findings were limited by several factors including the study design, which did not allow for showing a causal association of food deserts and food swamps with obesity-related cancer mortality, the researchers noted. Other limitations included the use of groups rather than individuals, the potential misclassification of food stores, and the use of county-level data on race, ethnicity, and income, they wrote.

The results indicate that “food swamps appear to be a growing epidemic across the U.S., likely because of systemic issues, and should draw concern and conversation from local and state officials,” the researchers concluded.
 

Community-level investments can benefit individual health

Dr. Bevel said he was not surprised by the findings, as he has seen firsthand the lack of healthy food options and growth of unhealthy food options, especially for certain populations in certain communities. “Typically, these are people who have lower socioeconomic status, primarily non-Hispanic Black or African American or Hispanic American,” he said “I have watched people have to choose between getting fruits/vegetables versus their medications or running to fast food places to feed their families. What is truly surprising is that we’re not talking about people’s lived environment enough for my taste,” he said.  

“I hope that our data and results can inform local and state policymakers to truly invest in all communities, such as funding for community gardens, and realize that adverse food environments, including the barriers in navigating these environments, have significant consequences on real people,” said Dr. Bevel. “Also, I hope that the results can help clinicians realize that a patient’s lived environment can truly affect their obesity and/or obesity-related cancer status; being cognizant of that is the first step in holistic, comprehensive care,” he said. 

“One role that oncologists might be able to play in improving patients’ access to healthier food is to create and/or implement healthy lifestyle programs with gardening components to combat the poorest food environments that their patients likely reside in,” said Dr. Bevel. Clinicians also could consider the innovative approach of “food prescriptions” to help reduce the effects of deprived, built environments, he noted.

Looking ahead, next steps for research include determining the severity of association between food swamps and obesity-related cancer by varying factors such as cancer type, and examining any potential racial disparities between people living in these environments and obesity-related cancer, Dr. Bevel added.
 

Data provide foundation for multilevel interventions

The current study findings “raise a clarion call to elevate the discussion on food availability and access to ensure an equitable emphasis on both the importance of lifestyle factors and the upstream structural, economic, and environmental contexts that shape these behaviors at the individual level,” Karriem S. Watson, DHSc, MS, MPH, of the National Institutes of Health, Bethesda, Md., and Angela Odoms-Young, PhD, of Cornell University, Ithaca, N.Y., wrote in an accompanying editorial.

The findings provide a foundation for studies of obesity-related cancer outcomes that take the community environment into consideration, they added.

The causes of both obesity and cancer are complex, and the study findings suggest that the links between unhealthy food environments and obesity-related cancer may go beyond dietary consumption alone and extend to social and psychological factors, the editorialists noted.

“Whether dealing with the lack of access to healthy foods or an overabundance of unhealthy food, there is a critical need to develop additional research that explores the associations between obesity-related cancer mortality and food inequities,” they concluded.

The study received no outside funding. The researchers and the editorialists had no financial conflicts to disclose.

Communities with easy access to fast food were 77% more likely to have high levels of obesity-related cancer mortality, based on data from a new cross-sectional study of more than 3,000 communities.

Although increased healthy eating has been associated with reduced risk of obesity and with reduced cancer incidence and mortality, access to healthier eating remains a challenge in communities with less access to grocery stores and healthy food options (food deserts) and/or easy access to convenience stores and fast food (food swamps), Malcolm Seth Bevel, PhD, of the Medical College of Georgia, Augusta, and colleagues, wrote in their paper, published in JAMA Oncology.

In addition, data on the association between food deserts and swamps and obesity-related cancer mortality are limited, they said.

“We felt that the study was important given the fact that obesity is an epidemic in the United States, and multiple factors contribute to obesity, especially adverse food environments,” Dr. Bevel said in an interview. “Also, I lived in these areas my whole life, and saw how it affected underserved populations. There was a story that needed to be told, so we’re telling it,” he said in an interview.

In a study, the researchers analyzed food access and cancer mortality data from 3,038 counties across the United States. The food access data came from the U.S. Department of Agriculture Food Environment Atlas (FEA) for the years 2012, 2014, 2015, 2017, and 2020. Data on obesity-related cancer mortality came from the Centers for Disease Control and Prevention for the years from 2010 to 2020.

Food desert scores were calculated through data from the FEA, and food swamp scores were based on the ratio of fast-food restaurants and convenience stores to grocery stores and farmers markets in a modification of the Retail Food Environment Index score.

The researchers used an age-adjusted, multiple regression model to determine the association between food desert and food swamp scores and obesity-related cancer mortality rates. Higher food swamp and food desert scores (defined as 20.0 to 58.0 or higher) were used to classify counties as having fewer healthy food resources. The primary outcome was obesity-related cancer mortality, defined as high or low (71.8 or higher per 100,000 individuals and less than 71.8 per 100,000 individuals, respectively).

Overall, high rates of obesity-related cancer mortality were 77% more likely in the counties that met the criteria for high food swamp scores (adjusted odds ratio 1.77). In addition, researchers found a positive dose-response relationship among three levels of both food desert scores and food swamp scores and obesity-related cancer mortality.

A total of 758 counties had obesity-related cancer mortality rates in the highest quartile. Compared to counties with low rates of obesity-related cancer mortality, counties with high rates of obesity-related cancer mortality also had a higher percentage of non-Hispanic Black residents (3.26% vs. 1.77%), higher percentage of adults older than 65 years (15.71% vs. 15.40%), higher rates of adult obesity (33.0% vs. 32.10%), and higher rates of adult diabetes (12.50% vs. 10.70%).

SAN DIEGO – Primary care providers can draw from a wide range of diets to give patients evidence-based advice on how to lose weight, prevent diabetes, and achieve other health goals, according to a speaker at the annual meeting of the American College of Physicians.

“Evidence from studies can help clinicians and their patients develop a successful dietary management plan and achieve optimal health,” said internist Michelle Hauser, MD, clinical associate professor at Stanford (Calif.) University. She also discussed evidence-based techniques to support patients in maintaining dietary modifications.
 

Predominantly plant‐based diets

Popular predominantly plant‐based diets include a Mediterranean diet, healthy vegetarian diet, predominantly whole-food plant‐based (WFPB) diet, and a dietary approach to stop hypertension (DASH).

The DASH diet was originally designed to help patients manage their blood pressure, but evidence suggests that it also can help adults with obesity lose weight. In contrast to the DASH diet, the Mediterranean diet is not low-fat and not very restrictive. Yet the evidence suggests that the Mediterranean diet is not only helpful for losing weight but also can reduce the risk of various chronic diseases, including obesity, type 2 diabetes, cardiovascular disease (CVD), and cancer, Dr. Hauser said. In addition, data suggest that the Mediterranean diet may reduce the risk of all-cause mortality and lower the levels of cholesterol.

“I like to highlight all these protective effects to my patients, because even if their goal is to lose weight, knowing that hard work pays off in additional ways can keep them motivated,” Dr. Hauser stated.

A healthy vegetarian diet and a WFPB diet are similar, and both are helpful in weight loss and management of total cholesterol and LDL‐C levels. Furthermore, healthy vegetarian and WFPB diets may reduce the risk of type 2 diabetes, CVD, and some cancers. Cohort study data suggest that progressively more vegetarian diets are associated with lower BMIs.

“My interpretation of these data is that predominantly plant-based diets rich in whole foods are healthful and can be done in a way that is sustainable for most,” said Dr. Hauser. However, this generally requires a lot of support at the outset to address gaps in knowledge, skills, and other potential barriers.

For example, she referred one obese patient at risk of diabetes and cardiovascular disease to a registered dietitian to develop a dietary plan. The patient also attended a behavioral medicine weight management program to learn strategies such as using smaller plates, and his family attended a healthy cooking class together to improve meal planning and cooking skills.
 

Time‐restricted feeding

There are numerous variations of time-restricted feeding, commonly referred to as intermittent fasting, but the principles are similar – limiting food intake to a specific window of time each day or week.

Although some studies have shown that time-restricted feeding may help patients reduce adiposity and improve lipid markers, most studies comparing time-restricted feeding to a calorie-restricted diet have shown little to no difference in weight-related outcomes, Dr. Hauser said.

These data suggest that time-restricted feeding may help patients with weight loss only if time restriction helps them reduce calorie intake. She also warned that time-restrictive feeding might cause late-night cravings and might not be helpful in individuals prone to food cravings.
 

Low‐carbohydrate and ketogenic diets

Losing muscle mass can prevent some people from dieting, but evidence suggests that a high-fat, very low-carbohydrate diet – also called a ketogenic diet – may help patients reduce weight and fat mass while preserving fat‐free mass, Dr. Hauser said.

The evidence regarding the usefulness of a low-carbohydrate (non-keto) diet is less clear because most studies compared it to a low-fat diet, and these two diets might lead to a similar extent of weight loss.
 

Rating the level of scientific evidence behind different diet options

Nutrition studies do no provide the same level of evidence as drug studies, said Dr. Hauser, because it is easier to conduct a randomized controlled trial of a drug versus placebo. Diets have many more variables, and it also takes much longer to observe most outcomes of a dietary change.

In addition, clinical trials of dietary interventions are typically short and focus on disease markers such as serum lipids and hemoglobin A1c levels. To obtain reliable information on the usefulness of a diet, researchers need to collect detailed health and lifestyle information from hundreds of thousands of people over several decades, which is not always feasible. “This is why meta-analyses of pooled dietary study data are more likely to yield dependable findings,” she noted.
 

Getting to know patients is essential to help them maintain diet modifications

When developing a diet plan for a patient, it is important to consider the sustainability of a dietary pattern. “The benefits of any healthy dietary change will only last as long as they can be maintained,” said Dr. Hauser. “Counseling someone on choosing an appropriate long-term dietary pattern requires getting to know them – taste preferences, food traditions, barriers, facilitators, food access, and time and cost restrictions.”

In an interview after the session, David Bittleman, MD, an internist at Veterans Affairs San Diego Health Care System, agreed that getting to know patients is essential for successfully advising them on diet.

“I always start developing a diet plan by trying to find out what [a patient’s] diet is like and what their goals are. I need to know what they are already doing in order to make suggestions about what they can do to make their diet healthier,” he said.

When asked about her approach to supporting patients in the long term, Dr. Hauser said that she recommends sequential, gradual changes. Dr. Hauser added that she suggests her patients prioritize implementing dietary changes that they are confident they can maintain.

Dr. Hauser and Dr. Bittleman report no relevant financial relationships.

An evidence-based analysis of 10 popular dietary patterns shows that some promote heart health better than others.

A new American Heart Association scientific statement concludes that the Mediterranean, Dietary Approach to Stop Hypertension (DASH), pescatarian, and vegetarian eating patterns most strongly align with heart-healthy eating guidelines issued by the AHA in 2021, whereas the popular paleolithic (paleo) and ketogenic (keto) diets fall short.

“The good news for the public and their clinicians is that there are several dietary patterns that allow for substantial flexibility for following a heart healthy diet – DASH, Mediterranean, vegetarian,” writing-group chair Christopher Gardner, PhD, with Stanford (Calif.) University, told this news organization.

“The number of different, popular dietary patterns has proliferated in recent years, and the amount of misinformation about them on social media has reached critical levels,” Dr. Gardner said in a news release.

“The public – and even many health care professionals – may rightfully be confused about heart-healthy eating, and they may feel that they don’t have the time or the training to evaluate the different diets. We hope this statement serves as a tool for clinicians and the public to understand which diets promote good cardiometabolic health,” he noted.

The writing group rated on a scale of 1-100 how well 10 popular diets or eating patterns align with AHA dietary advice for heart-healthy eating.

That advice includes consuming a wide variety of fruits and vegetables; choosing mostly whole grains instead of refined grains; using liquid plant oils rather than tropical oils; eating healthy sources of protein, such as from plants, seafood, or lean meats; minimizing added sugars and salt; limiting alcohol; choosing minimally processed foods instead of ultraprocessed foods; and following this guidance wherever food is prepared or consumed.

The 10 diets/dietary patterns were DASH, Mediterranean-style, pescatarian, ovo-lacto vegetarian, vegan, low-fat, very low–fat, low-carbohydrate, paleo, and very low–carbohydrate/keto patterns.

The diets were divided into four tiers on the basis of their scores, which ranged from a low of 31 to a high of 100.

Only the DASH eating plan got a perfect score of 100. This eating pattern is low in salt, added sugar, tropical oil, alcohol, and processed foods and high in nonstarchy vegetables, fruits, whole grains, and legumes. Proteins are mostly plant-based, such as legumes, beans, or nuts, along with fish or seafood, lean poultry and meats, and low-fat or fat-free dairy products.

The Mediterranean eating pattern achieved a slightly lower score of 89 because unlike DASH, it allows for moderate alcohol consumption and does not address added salt.

The other two top tier eating patterns were pescatarian, with a score of 92, and vegetarian, with a score of 86.

“If implemented as intended, the top-tier dietary patterns align best with the American Heart Association’s guidance and may be adapted to respect cultural practices, food preferences and budgets to enable people to always eat this way, for the long term,” Dr. Gardner said in the release.

Vegan and low-fat diets (each with a score of 78) fell into the second tier.

Though these diets emphasize fruits, vegetables, whole grains, legumes, and nuts while limiting alcohol and added sugars, the vegan diet is so restrictive that it could be challenging to follow long-term or when eating out and may increase the risk for vitamin B12 deficiency, which can lead to anemia, the writing group notes.

There also are concerns that low-fat diets treat all fats equally, whereas the AHA guidance calls for replacing saturated fats with healthier fats, they point out.

The third tier includes the very low–fat diet (score 72) and low-carb diet (score 64), whereas the paleo and very low–carb/keto diets fall into the fourth tier, with the lowest scores of 53 and 31, respectively.

Dr. Gardner said that it’s important to note that all 10 diet patterns “share four positive characteristics: more veggies, more whole foods, less added sugars, less refined grains.”

“These are all areas for which Americans have substantial room for improvement, and these are all things that we could work on together. Progress across these aspects would make a large difference in the heart-healthiness of the U.S. diet,” he told this news organization.

This scientific statement was prepared by the volunteer writing group on behalf of the AHA Council on Lifestyle and Cardiometabolic Health, the Council on Cardiovascular and Stroke Nursing, the Council on Hypertension, and the Council on Peripheral Vascular Disease.

An evidence-based analysis of 10 popular dietary patterns shows that some promote heart health better than others.

A new American Heart Association scientific statement concludes that the Mediterranean, Dietary Approach to Stop Hypertension (DASH), pescatarian, and vegetarian eating patterns most strongly align with heart-healthy eating guidelines issued by the AHA in 2021, whereas the popular paleolithic (paleo) and ketogenic (keto) diets fall short.

“The good news for the public and their clinicians is that there are several dietary patterns that allow for substantial flexibility for following a heart healthy diet – DASH, Mediterranean, vegetarian,” writing-group chair Christopher Gardner, PhD, with Stanford (Calif.) University, told this news organization.

SAN DIEGO – For patients with obesity, surgery, lifestyle changes, and pharmacologic interventions are all treatment options, but antiobesity medications provide a better risk-to-benefit ratio, according to a presenter at the annual meeting of the American College of Physicians.

Lifestyle changes result in the least weight loss and may be safest, while surgery provides the most weight loss and has the greatest risk. Antiobesity medications, especially the newer ones used in combination with lifestyle changes, can provide significant and sustained weight loss with manageable side effects, said Daniel Bessesen, MD, a professor in the endocrinology, diabetes, and metabolism at University of Colorado at Denver, Aurora.

New and more effective antiobesity medications have given internists more potential options to discuss with their patients, Dr. Bessesen said. He reviewed the pros and cons of the different options.

Medications are indicated for patients with a body mass index greater than 30, including those with a weight-related comorbidity, Dr. Bessesen said. The average weight loss is 5%-15% over 3-6 months but may vary greatly. Insurance often does not cover the medication costs.
 

Older FDA-approved antiobesity medications

Phentermine is the most widely prescribed antiobesity medication, partly because it is the only option most people can afford out of pocket. Dr. Bessesen presented recent data showing that long-term use of phentermine was associated with greater weight loss and that patients continuously taking phentermine for 24 months lost 7.5% of their weight.

Phentermine suppresses appetite by increasing norepinephrine production. Dr. Bessesen warned that internists should be careful when prescribing it to patients with mental conditions, because it acts as a stimulant. Early studies raised concerns about the risk of cardiovascular disease (CVD) in patients taking phentermine. However, analysis of data from over 13,000 individuals showed no evidence of a relationship between phentermine exposure and CVD events.

“These data provide some reassurance that it could be used in patients with CVD risk,” he noted. Phentermine can also be combined with topiramate extended release, a combination that provides greater efficacy (up to 10% weight loss) with fewer side effects. However, this combination is less effective in patients with diabetes than in those without.

Additional treatment options included orlistat and naltrexone sustained release/bupropion SR. Orlistat is a good treatment alternative for patients with constipation and is the safest option among older anti-obesity medications, whereas naltrexone SR/bupropion SR may be useful in patients with food cravings. However, there is more variability in the individual-level benefit from these agents compared to phentermine and phentermine/topiramate ER, Dr. Bessesen said.
 

Newer anti‐obesity medications

Liraglutide, an agent used for the management of type 2 diabetes, has recently been approved for weight loss. Liraglutide causes moderate weight loss, and it may reduce the risk of CVD. However, there are tolerability issues, such as nausea and other risks, and Dr. Bessesen advises internists to “start at low doses and increase slowly.”

Semaglutide is the newest and most effective antiobesity drug approved by the Food and Drug Administration, providing sustained weight loss of 8% for up to 48 weeks after starting treatment. Although its efficacy is lower in patients with diabetes, Dr. Bessesen noted that “this is common for antiobesity agents, and clinicians should not refrain from prescribing it in this population.”

Setmelanotide is another new medication approved for chronic weight management in patients with monogenic obesity. This medication can be considered for patients with early-onset severe obesity with abnormal feeding behavior.

Commenting on barriers to access to new antiobesity medications, Dr. Bessesen said that “the high cost of these medications is a substantial problem, but as more companies become involved and products are on the market for a longer period of time, I am hopeful that prices will come down.”
 

Emerging antiobesity medications

Dr. Bessesen presented recent phase 3 data showing that treatment with tirzepatide provided sustained chronic loss and improved cardiometabolic measures with no diet. Tirzepatide, which targets receptors for glucagonlike peptide–1 and glucose-dependent insulinotropic polypeptide, is used for the management of type 2 diabetes and is expected to be reviewed soon by the FDA for its use in weight management.

A semaglutide/cagrilintide combination may also provide a new treatment option for patients with obesity. In a phase 1b trial, semaglutide/cagrilintide treatment resulted in up to 17% weight loss in patients with obesity who were otherwise healthy; however, phase 2 and 3 data are needed to confirm its efficacy.
 

A ‘holistic approach’

When deciding whether to prescribe antiobesity medications, Dr. Bessesen noted that medications are better than exercise alone. Factors to consider when deciding whether to prescribe drugs, as well as which ones, include costs, local regulatory guidelines, requirement for long-term use, and patient comorbidities.

He also stated that lifestyle changes, such as adopting healthy nutrition and exercising regularly, are also important and can enhance weight loss when combined with medications.

Richele Corrado, DO, MPH, agreed that lifestyle management in combination with medications may provide greater weight loss than each of these interventions alone.

“If you look at the data, exercise doesn’t help you lose much weight,” said Dr. Corrado, a staff internist and obesity medicine specialist at Walter Reed National Military Medical Center in Bethesda, Md., who spoke at the same session. She added that she has many patients who struggle to lose weight despite having a healthy lifestyle. “It’s important to discuss with these patients about medications and surgery.”

Dr. Bessesen noted that management of mental health and emotional well-being should also be an integral part of obesity management. “Treatment for obesity may be more successful when underlying psychological conditions such as depression, childhood sexual trauma, or anxiety are addressed and treated,” he said.

Dr. Bessesen was involved in the study of the efficacy of semaglutide/cagrilintide. He does not have any financial conflicts with the companies that make other mentioned medications. He has received research grants or contracts from Novo Nordisk, honoraria from Novo Nordisk, and consultantship from Eli Lilly. Dr. Corrado reported no relevant financial conflicts.

Seven months after Lahavah Wallace’s weight-loss operation, a New York bariatric surgery practice sued her, accusing her of “intentionally” failing to pay nearly $18,000 of her bill.

Long Island Minimally Invasive Surgery, which does business as the New York Bariatric Group, went on to accuse Ms. Wallace of “embezzlement,” alleging she kept insurance payments that should have been turned over to the practice.

Ms. Wallace denies the allegations, which the bariatric practice has leveled against patients in hundreds of debt-collection lawsuits filed over the past 4 years, court records in New York state show.

In about 60 cases, the lawsuits demanded $100,000 or more from patients. Some patients were found liable for tens of thousands of dollars in interest charges or wound up shackled with debt that could take a decade or more to shake. Others are facing the likely prospect of six-figure financial penalties, court records show.

Backed by a major private equity firm, the bariatric practice spends millions each year on advertisements featuring patients who have dropped 100 pounds or more after bariatric procedures, sometimes having had a portion of their stomachs removed. The ads have run on TV, online, and on New York City subway posters.

The online ads, often showcasing the slogan “Stop obesity for life,” appealed to Ms. Wallace, who lives in Brooklyn and works as a legal assistant for the state of New York. She said she turned over checks from her insurer to the bariatric group and was stunned when the medical practice hauled her into court citing an “out-of-network payment agreement” she had signed before her surgery.

“I really didn’t know what I was signing,” Ms. Wallace told KFF Health News. “I didn’t pay enough attention.”

Shawn Garber, MD, a bariatric surgeon who founded the practice in 2000 on Long Island and serves as its CEO, said that “prior to rendering services” his office staff advises patients of the costs and their responsibility to pay the bill.

The bariatric group has cited these out-of-network payment agreements in at least 300 lawsuits filed against patients from January 2019 to 2022 demanding nearly $19 million to cover medical bills, interest charges, and attorney’s fees, a KFF Health News review of New York state court records found.

Danny De Voe, a partner at Sahn Ward Braff Koblenz law firm in Uniondale, N.Y., who filed many of those suits, declined to comment, citing attorney-client privilege.

In most cases, the medical practice had agreed to accept an insurance company’s out-of-network rate as full payment for its services – with caveats, according to court filings.

In the agreements they signed, patients promised to pay any coinsurance, meeting any deductible, and pass on to the medical practice any reimbursement checks they received from their health plans within 7 days.

Patients who fail to do so “will be held responsible for the full amount charged for your surgery, plus the cost of legal fees,” the agreement states.

That “full amount” can be thousands of dollars higher than what insurers would likely pay, KFF Health News found – while legal fees and other costs can layer on thousands more.

Elisabeth Benjamin, a lawyer with the Community Service Society of New York, said conflicts can arise when insurers send checks to pay for out-of-network medical services to patients rather than reimbursing a medical provider directly.

“We would prefer to see regulators step in and stop that practice,” she said, adding it “causes tension between providers and patients.”

That’s certainly true for Ms. Wallace. The surgery practice sued her in August 2022demanding $17,981 in fees it said remained unpaid after her January 2022 laparoscopic sleeve gastrectomy, an operation in which much of the stomach is removed to assist weight loss.

The lawsuit also tacked on a demand for $5,993 in attorney’s fees, court records show.

The suit alleges Ms. Wallace signed the contract even though she “had no intention” of paying her bills. The complaint goes on to accuse her of “committing embezzlement” by “willfully, intentionally, deliberately and maliciously” depositing checks from her health plan into her personal account.

The suit doesn’t include details to substantiate these claims, and Ms. Wallace said in her court response they are not true. Ms. Wallace said she turned over checks for the charges.

“They billed the insurance for everything they possibly could,” Ms. Wallace said.

In September, Ms. Wallace filed for bankruptcy, hoping to discharge the bariatric care debt along with about $4,700 in unrelated credit card charges.

The medical practice fired back in November by filing an “adversary complaint” in her Brooklyn bankruptcy court proceeding that argues her medical debt should not be forgiven because Ms. Wallace committed fraud.

The adversary complaint, which is pending in the bankruptcy case, accuses Ms. Wallace of “fraudulently” inducing the surgery center to perform “elective medical procedures” without requiring payment up front.

Both the harsh wording and claims of wrongdoing have infuriated Ms. Wallace and her attorney, Jacob Silver, of Brooklyn.

Mr. Silver wants the medical practice to turn over records of the payments received from Ms. Wallace. “There is no fraud here,” he said. “This is frivolous. We are taking a no-settlement position.”
 

Gaining debt

Few patients sued by the bariatric practice mount a defense in court and those who do fight often lose, court records show.

The medical practice won default judgments totaling nearly $6 million in about 90 of the 300 cases in the sample reviewed by KFF Health News. Default judgments are entered when the defendant fails to respond.

Many cases either are pending, or it is not clear from court filings how they were resolved.

Some patients tried to argue that the fees were too high or that they didn’t understand going in how much they could owe. One woman, trying to push back against a demand for more than $100,000, said in a legal filing that she “was given numerous papers to sign without anyone of the staff members explaining to me what it actually meant.” Another patient, who was sued for more than $40,000, wrote: “I don’t have the means to pay this bill.”

Among the cases described in court records:

• A Westchester County, N.Y., woman was sued for $102,556 and settled for $72,000 in May 2021. She agreed to pay $7,500 upon signing the settlement and $500 a month from September 2021 to May 2032.
• A Peekskill, N.Y., woman in a December 2019 judgment was held liable for $384,092, which included $94,047 in interest.
• A Newburgh, N.Y., man was sued in 2021 for $252,309 in medical bills, 12% interest, and $84,103 in attorneys’ fees. The case is pending.

Robert Cohen, a longtime attorney for the bariatric practice, testified in a November 2021 hearing that the lawyers take “a contingency fee of one-third of our recovery” in these cases. In that case, Mr. Cohen had requested $13,578 based on his contingency fee arrangement. He testified that he spent 7.3 hours on the case and that his customary billing rate was $475 per hour, which came to $3,467.50. The judge awarded the lower amount, according to a transcript of the hearing.

Teresa LaMasters, MD, president of the American Society for Metabolic and Bariatric Surgery, said suing patients for large sums “is not a common practice” among bariatric surgeons.

“This is not what the vast majority in the field would espouse,” she said.

But Dr. Garber, the NYBG’s chief executive, suggested patients deserve blame.

“These lawsuits stem from these patients stealing the insurance money rather than forwarding it onto NYBG as they are morally and contractually obligated to do,” Dr. Garber wrote in an email to KFF Health News.

Dr. Garber added: “The issue is not with what we bill, but rather with the fact that the insurance companies refuse to send payment directly to us.”
 

‘A kooky system’

Defense attorneys argue that many patients don’t fully comprehend the perils of failing to pay on time – for whatever reason.

In a few cases, patients admitted pocketing checks they were obligated to turn over to the medical practice. But for the most part, court records don’t specify how many such checks were issued and for what amounts – or whether the patient improperly cashed them.

“It’s a kooky system,” said Paul Brite, an attorney who has faced off against the bariatric practice in court.

“You sign these documents that could cost you tons of money. It shouldn’t be that way,” he said. “This can ruin their financial life.”

New York lawmakers have acted to limit the damage from medical debt, including “surprise bills.”

In November, Democratic Gov. Kathy Hochul signed legislation that prohibits health care providers from slapping liens on a primary residence or garnishing wages.

But contracts with onerous repayment terms represent an “evolving area of law” and an alarming “new twist” on concerns over medical debt, said Ms. Benjamin, the community service society lawyer.

She said contract “accelerator clauses” that trigger severe penalties if patients miss payments should not be permitted for medical debt.

“If you default, the full amount is due,” she said. “This is really a bummer.”
 

‘Fair market value’

The debt collection lawsuits argue that weight-loss patients had agreed to pay “fair market value” for services – and the doctors are only trying to secure money they are due.

But some prices far exceed typical insurance payments for obesity treatments across the country, according to a medical billing data registry. Surgeons performed about 200,000 bariatric operations in 2020, according to the bariatric surgery society.

Ms. Wallace, the Brooklyn legal assistant, was billed $60,500 for her lap sleeve gastrectomy, though how much her insurance actually paid remains to be hashed out in court.

Michael Arrigo, a California medical billing expert at No World Borders, called the prices “outrageous” and “unreasonable and, in fact, likely unconscionable.”

“I disagree that these are fair market charges,” he said.

Dr. LaMasters called the gastrectomy price billed to Ms. Wallace “really expensive” and “a severe outlier.” While charges vary by region, she quoted a typical price of around $22,000.

Dr. Garber said NYBG “bills at usual and customary rates” determined by Fair Health, a New York City-based repository of insurance claims data. Fair Health “sets these rates based upon the acceptable price for our geographic location,” he said.

But Rachel Kent, Fair Health’s senior director of marketing, told KFF Health News that the group “does not set rates, nor determine or take any position on what constitutes ‘usual and customary rates.’ ” Instead, it reports the prices providers are charging in a given area.

Overall, Fair Health data shows huge price variations even in adjacent ZIP codes in the metro area. In Long Island’s Roslyn Heights neighborhood, where NYBG is based, Fair Health lists the out-of-network price charged by providers in the area as $60,500, the figure Ms. Wallace was billed.

But in several other New York City–area ZIP codes the price charged for the gastrectomy procedure hovers around $20,000, according to the data bank. The price in Manhattan is $17,500, for instance, according to Fair Health.

Nationwide, the average cost in 2021 for bariatric surgery done in a hospital was $32,868, according to a KFF analysis of health insurance claims.
 

Private equity arrives

Dr. Garber said in a court affidavit in May 2022 that he founded the bariatric practice “with a singular focus: providing safe, effective care to patients suffering from obesity and its resulting complications.”

Under his leadership, the practice has “developed into New York’s elite institution for obesity treatment,” Dr. Garber said. He said the group’s surgeons are “highly sought after to train other bariatric surgeons throughout the country and are active in the development of new, cutting-edge bariatric surgery techniques.”

In 2017, Dr. Garber and partners agreed on a business plan to help spur growth and “attract private equity investment,” according to the affidavit.

They formed a separate company to handle the bariatric practice’s business side. Known as management services organizations, such companies provide a way for private equity investors to circumvent laws in some states that prohibit nonphysicians from owning a stake in a medical practice.

In August 2019, the private equity firm Sentinel Capital Partners bought 65% of the MSO for $156.5 million, according to Dr. Garber’s affidavit. The management company is now known as New You Bariatric Group. The private equity firm did not respond to requests for comment.

Dr. Garber, in a September 2021 American Society for Metabolic and Bariatric Surgery webinar viewable online, said the weight-loss practice spends $6 million a year on media and marketing directly to patients – and is on a roll. Nationally, bariatric surgery is growing 6% annually, he said. NYBG boasts two dozen offices in the tri-state area of New York, New Jersey, and Connecticut and is poised to expand into more states.

“Since private equity, we’ve been growing at 30%-40% year over year,” Dr. Garber said.

KFF is an endowed nonprofit organization providing information on health issues to the nation.

Seven months after Lahavah Wallace’s weight-loss operation, a New York bariatric surgery practice sued her, accusing her of “intentionally” failing to pay nearly $18,000 of her bill.

Long Island Minimally Invasive Surgery, which does business as the New York Bariatric Group, went on to accuse Ms. Wallace of “embezzlement,” alleging she kept insurance payments that should have been turned over to the practice.

Ms. Wallace denies the allegations, which the bariatric practice has leveled against patients in hundreds of debt-collection lawsuits filed over the past 4 years, court records in New York state show.

In about 60 cases, the lawsuits demanded $100,000 or more from patients. Some patients were found liable for tens of thousands of dollars in interest charges or wound up shackled with debt that could take a decade or more to shake. Others are facing the likely prospect of six-figure financial penalties, court records show.

Backed by a major private equity firm, the bariatric practice spends millions each year on advertisements featuring patients who have dropped 100 pounds or more after bariatric procedures, sometimes having had a portion of their stomachs removed. The ads have run on TV, online, and on New York City subway posters.

The online ads, often showcasing the slogan “Stop obesity for life,” appealed to Ms. Wallace, who lives in Brooklyn and works as a legal assistant for the state of New York. She said she turned over checks from her insurer to the bariatric group and was stunned when the medical practice hauled her into court citing an “out-of-network payment agreement” she had signed before her surgery.

“I really didn’t know what I was signing,” Ms. Wallace told KFF Health News. “I didn’t pay enough attention.”

Shawn Garber, MD, a bariatric surgeon who founded the practice in 2000 on Long Island and serves as its CEO, said that “prior to rendering services” his office staff advises patients of the costs and their responsibility to pay the bill.

The bariatric group has cited these out-of-network payment agreements in at least 300 lawsuits filed against patients from January 2019 to 2022 demanding nearly $19 million to cover medical bills, interest charges, and attorney’s fees, a KFF Health News review of New York state court records found.

Danny De Voe, a partner at Sahn Ward Braff Koblenz law firm in Uniondale, N.Y., who filed many of those suits, declined to comment, citing attorney-client privilege.

In most cases, the medical practice had agreed to accept an insurance company’s out-of-network rate as full payment for its services – with caveats, according to court filings.

In the agreements they signed, patients promised to pay any coinsurance, meeting any deductible, and pass on to the medical practice any reimbursement checks they received from their health plans within 7 days.

Patients who fail to do so “will be held responsible for the full amount charged for your surgery, plus the cost of legal fees,” the agreement states.

That “full amount” can be thousands of dollars higher than what insurers would likely pay, KFF Health News found – while legal fees and other costs can layer on thousands more.

Elisabeth Benjamin, a lawyer with the Community Service Society of New York, said conflicts can arise when insurers send checks to pay for out-of-network medical services to patients rather than reimbursing a medical provider directly.

“We would prefer to see regulators step in and stop that practice,” she said, adding it “causes tension between providers and patients.”

That’s certainly true for Ms. Wallace. The surgery practice sued her in August 2022demanding $17,981 in fees it said remained unpaid after her January 2022 laparoscopic sleeve gastrectomy, an operation in which much of the stomach is removed to assist weight loss.

The lawsuit also tacked on a demand for $5,993 in attorney’s fees, court records show.

The suit alleges Ms. Wallace signed the contract even though she “had no intention” of paying her bills. The complaint goes on to accuse her of “committing embezzlement” by “willfully, intentionally, deliberately and maliciously” depositing checks from her health plan into her personal account.

“They billed the insurance for everything they possibly could,” Ms. Wallace said.

The medical practice fired back in November by filing an “adversary complaint” in her Brooklyn bankruptcy court proceeding that argues her medical debt should not be forgiven because Ms. Wallace committed fraud.

The adversary complaint, which is pending in the bankruptcy case, accuses Ms. Wallace of “fraudulently” inducing the surgery center to perform “elective medical procedures” without requiring payment up front.

Both the harsh wording and claims of wrongdoing have infuriated Ms. Wallace and her attorney, Jacob Silver, of Brooklyn.

Mr. Silver wants the medical practice to turn over records of the payments received from Ms. Wallace. “There is no fraud here,” he said. “This is frivolous. We are taking a no-settlement position.”

Overall, Fair Health data shows huge price variations even in adjacent ZIP codes in the metro area. In Long Island’s Roslyn Heights neighborhood, where NYBG is based, Fair Health lists the out-of-network price charged by providers in the area as $60,500, the figure Ms. Wallace was billed.

But in several other New York City–area ZIP codes the price charged for the gastrectomy procedure hovers around $20,000, according to the data bank. The price in Manhattan is $17,500, for instance, according to Fair Health.

Nationwide, the average cost in 2021 for bariatric surgery done in a hospital was $32,868, according to a KFF analysis of health insurance claims.
 

Private equity arrives

Dr. Garber said in a court affidavit in May 2022 that he founded the bariatric practice “with a singular focus: providing safe, effective care to patients suffering from obesity and its resulting complications.”

Under his leadership, the practice has “developed into New York’s elite institution for obesity treatment,” Dr. Garber said. He said the group’s surgeons are “highly sought after to train other bariatric surgeons throughout the country and are active in the development of new, cutting-edge bariatric surgery techniques.”

In 2017, Dr. Garber and partners agreed on a business plan to help spur growth and “attract private equity investment,” according to the affidavit.

They formed a separate company to handle the bariatric practice’s business side. Known as management services organizations, such companies provide a way for private equity investors to circumvent laws in some states that prohibit nonphysicians from owning a stake in a medical practice.

In August 2019, the private equity firm Sentinel Capital Partners bought 65% of the MSO for $156.5 million, according to Dr. Garber’s affidavit. The management company is now known as New You Bariatric Group. The private equity firm did not respond to requests for comment.

Dr. Garber, in a September 2021 American Society for Metabolic and Bariatric Surgery webinar viewable online, said the weight-loss practice spends $6 million a year on media and marketing directly to patients – and is on a roll. Nationally, bariatric surgery is growing 6% annually, he said. NYBG boasts two dozen offices in the tri-state area of New York, New Jersey, and Connecticut and is poised to expand into more states.

“Since private equity, we’ve been growing at 30%-40% year over year,” Dr. Garber said.

For years evidence has pointed to multiple health benefits associated with bariatric surgery, including improvements in diabetes, sleep apnea, and blood pressure. Now researchers are adding cutting cancer risk by more than half to the list.

A retrospective, observational study of patients with obesity at 47 U.S. health care organizations found that, over 10 years, 4% who had bariatric surgery developed certain cancers, compared with 8.9% of their peers who did not undergo such surgery.

“We did see a difference in breast cancer, colon cancer, liver cancer, and ovarian cancer incidence. ... with patients in the bariatric surgery group having lower incidence of these four types of cancers when compared to the nonsurgical control group,” said Vibhu Chittajallu, MD, lead author and a gastroenterology fellow at Case Western Reserve University and University Hospitals in Cleveland.

The obesity epidemic is “one of the most serious health challenges in the United States today,” Dr. Chittajallu added at an April 27 media briefing during which select research was previewed for the annual Digestive Disease Week®. Obesity has been associated with multiple serious illnesses, including type 2 diabetes, heart disease, and cancer.

Obesity is also common. The Centers for Disease Control and Prevention reports that nearly 42% of American adults have obesity, and rates continue to rise.

Dr. Chittajallu and colleagues used billing codes in a national database to identify 55,789 patients with obesity who underwent bariatric surgery (sleeve gastrectomy, gastric bypass, or gastric band procedures) and a control group of the same size who did not have surgery.

Investigators controlled for risk factors that contribute to cancer development, including smoking history, alcohol use, heart disease, and hormone therapies.

Key findings

In 10 years of follow-up, 2,206 patients who underwent bariatric surgery developed an obesity-associated cancer, compared with 4,960 patients who did not have bariatric surgery.

The bariatric surgery group had lower numbers of new cases for six types of cancers (Table 1).

‘Fascinating’ study but questions remain

The study is “fascinating,” said Loren Laine, MD, moderator of the media briefing. “Obesity is clearly associated with a number of different cancers, and that’s very important. So, it makes logical sense that if you lose weight, you will reduce that risk.”

Although investigators controlled for several known cancer risk factors, there are some they couldn’t control for because they were not included in the database, and there could be unknowns that also affected the results, noted Dr. Laine, who is professor of medicine (digestive diseases) and chief of digestive health at Yale University in New Haven, Conn.

“You have to be circumspect when you look at retrospective observational studies,” he added.

It would be helpful to know when most cancers developed over the 10 years, Dr. Laine said. Dr. Chittajallu responded that the research team did not include cancers that developed in the first year after bariatric surgery to minimize incidental findings, but he did not provide a timeline for the cancers that developed.

Another unanswered question, Dr. Laine said, is whether a dose-response relationship exists. If future research shows that the more weight a person loses, the more likely they are to have a reduction in cancer risk, “that would be fascinating,” he said. Also, it would be interesting to know if endoscopic interventions and weight-loss medications decrease cancer risks in people with obesity.

More research is needed to understand how bariatric surgery affects cancer risk, Dr. Chittajallu said. “But the significant findings from this study suggest it’s an exciting avenue for further study.”

DDW 2023 will be held May 6-9 in Chicago and virtually.

The study was independently supported. Dr. Chittajallu and Dr. Laine have reported no relevant financial relationships.

The meeting is sponsored by the American Gastroenterological Association, the American Association for the Study of Liver Diseases, the American Society for Gastrointestinal Endoscopy, and the Society for Surgery of the Alimentary Tract.

The lowest available national prices of drugs to treat obesity are up to 20 times higher than the estimated cost of profitable generic versions of the same agents, according to a new analysis.
 

The findings by Jacob Levi, MBBS, and colleagues were published in Obesity.

“Our study highlights the inequality in pricing that exists for effective antiobesity medications, which are largely unaffordable in most countries,” Dr. Levi, from Royal Free Hospital NHS Trust, London, said in a press release.

“We show that these drugs can actually be produced and sold profitably for low prices,” he summarized. “A public health approach that prioritizes improving access to medications should be adopted, instead of allowing companies to maximize profits,” Dr. Levi urged.

Dr. Levi and colleagues studied the oral agents orlistat, naltrexone/bupropion, topiramate/phentermine, and semaglutide, and subcutaneous liraglutide, semaglutide, and tirzepatide (all approved by the U.S. Food and Drug Administration to treat obesity, except for oral semaglutide and subcutaneous tirzepatide, which are not yet approved to treat obesity in the absence of type 2 diabetes).

“Worldwide, more people are dying from diabetes and clinical obesity than HIV, tuberculosis, and malaria combined now,” senior author Andrew Hill, MD, department of pharmacology and therapeutics, University of Liverpool, England, pointed out.
 

We need to repeat the low-cost success story with obesity drugs

“Millions of lives have been saved by treating infectious diseases at low cost in poor countries,” Dr. Hill continued. “Now we need to repeat this medical success story, with mass treatment of diabetes and clinical obesity at low prices.”

However, in an accompanying editorial, Eric A. Finkelstein, MD, and Junxing Chay, PhD, Duke-NUS Medical School, Singapore, maintain that “It would be great if everyone had affordable access to all medicines that might improve their health. Yet that is simply not possible, nor will it ever be.”

“What is truly needed is a better way to ration the health care dollars currently available in efforts to maximize population health. That is the challenge ahead not just for [antiobesity medications] but for all treatments,” they say.

“Greater use of cost-effectiveness analysis and direct negotiations, while maintaining the patent system, represents an appropriate approach for allocating scarce health care resources in the United States and beyond,” they continue.
 

Lowest current patented drug prices vs. estimated generic drug prices

New medications for obesity were highly effective in recent clinical trials, but high prices limit the ability of patients to get these medications, Dr. Levi and colleagues write.

They analyzed prices for obesity drugs in 16 low-, middle-, and high-income countries: Australia, Bangladesh, China, France, Germany, India, Kenya, Morocco, Norway, Peru, Pakistan, South Africa, Turkey, the United Kingdom, the United States, and Vietnam.

The researchers assessed the price of a 30-day supply of each of the studied branded drugs based on the lowest available price (in 2021 U.S. dollars) from multiple online national price databases.

Then they calculated the estimated minimum price of a 30-day supply of a potential generic version of these drugs, which included the cost of the active medicinal ingredients, the excipients (nonactive ingredients), the prefilled injectable device plus needles (for subcutaneous drugs), transportation, 10% profit, and 27% tax on profit.

The national prices of the branded medications for obesity were significantly higher than the estimated minimum prices of potential generic drugs (see Table).

The “twincretin” tirzepatide (Mounjaro) has proven successful in SURMOUNT-2, the second pivotal trial for the drug as an antiobesity agent, according to top-line results reported April 27 by tirzepatide’s manufacturer, Lilly, in a press release. The company reveals that tirzepatide achieved both of its primary endpoints in the trial, as well as all its key secondary endpoints.

The findings pave the way for tirzepatide to likely receive Food and Drug Administration approval as a treatment for obesity, perhaps before the end of 2023.

Tirzepatide received FDA approval in May 2022 for the treatment of type 2 diabetes in adults, under the brand name Mounjaro, and some people have already been using it off-label to treat obesity.

Tirzepatide is a dual glucagonlike peptide–1 (GLP-1) agonist and glucose-dependent insulinotropic polypeptide agonist. Several GLP-1 receptor agonists are already approved in the United States, including semaglutide, a once-weekly injection, which is approved as Wegovy for patients with obesity and as Ozempic for treatment of type 2 diabetes.

These agents have been incredibly popular among celebrity influencers, and with use of the #Ozempic hashtag and others on social media, this has led to unprecedented use of these products for weight loss, often among those who do not even have obesity or type 2 diabetes. Subsequently, patients with type 2 diabetes and obesity who need them have often struggled to obtain them, owing to shortages following this phenomenon.
 

SURMOUNT-2: Weight loss around 15%, less than seen in SURMOUNT-1

SURMOUNT-2 enrolled 938 adults with overweight or obesity and type 2 diabetes and had dual primary endpoints that both focused on weight loss, compared with placebo.

The first completed pivotal trial of tirzepatide for weight loss, SURMOUNT-1, enrolled people with overweight or obesity but no diabetes and had its main results reported in 2022. At the time, the weight loss achieved with tirzepatide, was described as “unprecedented,” with those given the highest dose in that trial (15 mg subcutaneously per week) losing an average of 20%-22% of body weight over 72 weeks, depending on the specific statistical analysis used.

For SURMOUNT-2’s first primary endpoint, 72 weeks of weekly subcutaneous injections with tirzepatide at dosages of 10 mg or 15 mg led to an average weight loss from baseline of 13.4% and 15.7%, respectively, compared with an average loss of 3.3% from baseline in the placebo-treated control arm.

For the second primary endpoint, 81.6% of people on the 10-mg dose and 86.4% on the 15-mg dose achieved at least 5% weight loss from baseline, compared with 30.5% of controls who had at least 5% weight loss from baseline.

In one key secondary endpoint, tirzepatide at dosages of 10 mg or 15 mg weekly produced at least a 15% cut in weight from baseline in 41.4% and 51.8% of participants, respectively, compared with a 2.6% rate of this endpoint in the placebo controls.

So the extent of weight loss seen in in SURMOUNT-2 was somewhat less than was reported in SURMOUNT-1, a finding consistent with many prior studies of incretin-based weight-loss agents, which seem to pack a more potent weight-loss punch in people without type 2 diabetes.

Lilly did not specifically report the treatment effect of tirzepatide on hemoglobin A1c in SURMOUNT-2, only saying that the effect was similar to what had been seen in the series of five SURPASS trials that led to the approval of tirzepatide for type 2 diabetes.

Lilly also reported that the safety profile of tirzepatide in SURMOUNT-2 generally matched what was seen in SURMOUNT-1 as well as in the SURPASS trials. The most common adverse events in SURMOUNT-2 involved gastrointestinal symptoms, such as nausea, diarrhea, and vomiting; these were generally mild to moderate in severity and clustered during the dose-escalation phase at the start of treatment. Treatment discontinuations caused by adverse effects were 3.8% on the 10-mg dosage, 7.4% on the 15-mg dosage, and 3.8% on placebo.

SURMOUNT-2 enrolled patients in the United States, Puerto Rico, and five other countries. All participants also received interventions designed to reduce their calorie intake and increase their physical activity.
 

More SURMOUNT-2 results at ADA in June

Lilly also announced that researchers would report more complete results from SURMOUNT-2 at the 2023 scientific sessions of the American Diabetes Association, being held in San Diego in late June, and publish the findings in a major medical journal.

Results from two additional phase 3 trials of tirzepatide in people with overweight or obesity, SURMOUNT-3 and SURMOUNT-4, are expected later in 2023.

Lilly started an application to the FDA for an indication for weight loss in October 2022 under a fast track designation by the agency, and the data collected in SURMOUNT-2 are expected to complete this application, which would then be subject to an FDA decision within about 6 months. Lilly said in its April 27 press release that it anticipates an FDA decision on this application may occur before the end of 2023.

SURMOUNT-2 and all of the other tirzepatide trials were sponsored by Lilly.

SURMOUNT-2 enrolled patients in the United States, Puerto Rico, and five other countries. All participants also received interventions designed to reduce their calorie intake and increase their physical activity.
 

More SURMOUNT-2 results at ADA in June

Lilly also announced that researchers would report more complete results from SURMOUNT-2 at the 2023 scientific sessions of the American Diabetes Association, being held in San Diego in late June, and publish the findings in a major medical journal.

Results from two additional phase 3 trials of tirzepatide in people with overweight or obesity, SURMOUNT-3 and SURMOUNT-4, are expected later in 2023.

Lilly started an application to the FDA for an indication for weight loss in October 2022 under a fast track designation by the agency, and the data collected in SURMOUNT-2 are expected to complete this application, which would then be subject to an FDA decision within about 6 months. Lilly said in its April 27 press release that it anticipates an FDA decision on this application may occur before the end of 2023.

SURMOUNT-2 and all of the other tirzepatide trials were sponsored by Lilly.

The “twincretin” tirzepatide (Mounjaro) has proven successful in SURMOUNT-2, the second pivotal trial for the drug as an antiobesity agent, according to top-line results reported April 27 by tirzepatide’s manufacturer, Lilly, in a press release. The company reveals that tirzepatide achieved both of its primary endpoints in the trial, as well as all its key secondary endpoints.

The findings pave the way for tirzepatide to likely receive Food and Drug Administration approval as a treatment for obesity, perhaps before the end of 2023.

Tirzepatide received FDA approval in May 2022 for the treatment of type 2 diabetes in adults, under the brand name Mounjaro, and some people have already been using it off-label to treat obesity.

Tirzepatide is a dual glucagonlike peptide–1 (GLP-1) agonist and glucose-dependent insulinotropic polypeptide agonist. Several GLP-1 receptor agonists are already approved in the United States, including semaglutide, a once-weekly injection, which is approved as Wegovy for patients with obesity and as Ozempic for treatment of type 2 diabetes.

These agents have been incredibly popular among celebrity influencers, and with use of the #Ozempic hashtag and others on social media, this has led to unprecedented use of these products for weight loss, often among those who do not even have obesity or type 2 diabetes. Subsequently, patients with type 2 diabetes and obesity who need them have often struggled to obtain them, owing to shortages following this phenomenon.
 

SURMOUNT-2: Weight loss around 15%, less than seen in SURMOUNT-1

SURMOUNT-2 enrolled 938 adults with overweight or obesity and type 2 diabetes and had dual primary endpoints that both focused on weight loss, compared with placebo.

The first completed pivotal trial of tirzepatide for weight loss, SURMOUNT-1, enrolled people with overweight or obesity but no diabetes and had its main results reported in 2022. At the time, the weight loss achieved with tirzepatide, was described as “unprecedented,” with those given the highest dose in that trial (15 mg subcutaneously per week) losing an average of 20%-22% of body weight over 72 weeks, depending on the specific statistical analysis used.

For SURMOUNT-2’s first primary endpoint, 72 weeks of weekly subcutaneous injections with tirzepatide at dosages of 10 mg or 15 mg led to an average weight loss from baseline of 13.4% and 15.7%, respectively, compared with an average loss of 3.3% from baseline in the placebo-treated control arm.

For the second primary endpoint, 81.6% of people on the 10-mg dose and 86.4% on the 15-mg dose achieved at least 5% weight loss from baseline, compared with 30.5% of controls who had at least 5% weight loss from baseline.

In one key secondary endpoint, tirzepatide at dosages of 10 mg or 15 mg weekly produced at least a 15% cut in weight from baseline in 41.4% and 51.8% of participants, respectively, compared with a 2.6% rate of this endpoint in the placebo controls.

So the extent of weight loss seen in in SURMOUNT-2 was somewhat less than was reported in SURMOUNT-1, a finding consistent with many prior studies of incretin-based weight-loss agents, which seem to pack a more potent weight-loss punch in people without type 2 diabetes.

Lilly did not specifically report the treatment effect of tirzepatide on hemoglobin A1c in SURMOUNT-2, only saying that the effect was similar to what had been seen in the series of five SURPASS trials that led to the approval of tirzepatide for type 2 diabetes.

Lilly also reported that the safety profile of tirzepatide in SURMOUNT-2 generally matched what was seen in SURMOUNT-1 as well as in the SURPASS trials. The most common adverse events in SURMOUNT-2 involved gastrointestinal symptoms, such as nausea, diarrhea, and vomiting; these were generally mild to moderate in severity and clustered during the dose-escalation phase at the start of treatment. Treatment discontinuations caused by adverse effects were 3.8% on the 10-mg dosage, 7.4% on the 15-mg dosage, and 3.8% on placebo.

SURMOUNT-2 enrolled patients in the United States, Puerto Rico, and five other countries. All participants also received interventions designed to reduce their calorie intake and increase their physical activity.
