Ghost Fat: The Unseen Consequences of Weight Loss
Many people who lose weight, whether through diet and lifestyle changes, medication, or bariatric surgery, recognize their body has changed. While they also experience improvements in quality of life and psychosocial areas, that’s not true for everyone. Some patients don’t “see” they’ve lost weight — a phenomenon referred to as “phantom fat,” “ghost fat,” or “vestigial body image.”
“Most people are happy with their appearance, or at least their body shape, after weight loss — although some are unhappy with the loose, sagging skin that can follow weight loss and seek plastic surgery to remedy that,” David B. Sarwer, PhD, director of the Center for Obesity Research and Education and professor of social and behavioral sciences, Temple University College of Public Health, Philadelphia, told this news organization. “There’s a subset of people who remain dissatisfied with their body image, including their shape.”
This body dissatisfaction of people who lose weight may be long-standing, predating the weight loss, or may be new because weight loss has catalyzed a host of previously unaddressed psychosocial issues. Some may show up at assessments on treatment onset, while others may be detected by monitoring changes during or after weight loss. “Mental health counseling after bariatric surgery is greatly underutilized,” Dr. Sarwer observed.
Ghost Fat
Research has corroborated the lingering self-perception of being “obese” vs “ex-obese.” In one study, patients who had undergone bariatric surgery reported being unable to see the difference in their size and shape 18-30 months following their procedure, despite substantial weight loss.
Some research suggests that rapid weight loss (eg, through bariatric surgery) is more likely to generate the perception of “phantom fat,” but additional research is needed to investigate whether the mode and speed of weight loss affect subsequent body image.
Being habituated to one’s former appearance may play a role, Dr. Sarwer suggested. “We see this not only with weight loss but with other body-altering procedures. It takes the brain time to catch up to the new appearance. In rhinoplasty, for example, it may take patients a while before they become accustomed to looking at their new face in the mirror after decades of looking at a more prominent nose.”
Years of Social Stigma
It may also take time for people to overcome years of enduring the stigma of obesity.
There are “pervasive” negative attitudes implying that individuals who are overweight and/or obese are “lazy, weak-willed, lacking in self-discipline and willpower” — a problem compounded by social media and media in general, which present unrealistic, glorified body images and disparaging messages about those with weight problems.
“Body image is a construct, rather than what you see in the mirror,” Sheethal Reddy, PhD, a psychologist at the Emory Bariatric Center, Emory University Hospital Midtown, Atlanta, told this news organization. “It’s the mental construct of our physical selves.”
According to Dr. Reddy, body image develops “within a broader societal context and is influenced by the person’s ethnic, racial, and cultural heritage.”
Adolescents are particularly vulnerable to body dissatisfaction. This is compounded in those with obesity, who often experience weight-based victimization and internalized weight-based stigma, compared with adolescents with lower weights. Weight stigma often takes the form of teasing and bullying.
“Appearance-related bullying and teasing during childhood and adolescence can reverberate into adulthood and persist throughout the lifespan,” Dr. Sarwer said. “When we see these patients and ask if they’ve ever been teased or bullied, not only do many say yes but it takes them back to those moments, to that origin story, and they remember someone saying something mean, cruel, and hurtful.”
Stigmatizing experiences can affect subjective body image, even after the weight has been lost and the person’s body is objectively thinner. Research comparing individuals who were overweight and lost weight to individuals who are currently overweight and haven’t lost weight and individuals who were never overweight suggests that “vestigial” body disparagement may persist following weight loss — especially in those with early-onset obesity.
The Role of Genetics
Genetics may contribute to people’s self-perception and body dissatisfaction, both before and after weight loss. A study of 827 community-based adolescents examined the association between polygenic risk scores (PRS) for body mass index (BMI) and type 2 diabetes and symptoms of body dissatisfaction and depression.
“Given the significant genetic role in BMI, we wanted to explore whether genetic risk for BMI might also predict body dissatisfaction,” lead author Krista Ekberg, MS, a doctoral candidate in clinical psychology, Rosalind Franklin University of Medicine and Science, North Chicago, Illinois, told this news organization.
Genetic influences on BMI, as measured by PRS, were significantly associated with both phenotypic BMI and body dissatisfaction. “The association between PRS and body dissatisfaction was largely explained by BMI, suggesting that BMI itself accounts for much of the link between genetic risk and body dissatisfaction.”
Psychiatric History and Trauma
Adverse experiences, particularly sexual or physical abuse, may also account for body dissatisfaction after weight loss. “When some people with a history of this type of abuse lose a large amount of weight — typically after bariatric surgery — they often go through a period of emotional turbulence,” Dr. Sarwer said.
Childhood maltreatment can also be associated with body image disturbances in adulthood, according to a meta-analysis of 12 studies, encompassing 15,481 participants. Sexual abuse is “surprisingly common” among patients with obesity, according to Dr. Sarwer. A chart review of 131 patients revealed that 60% of those who reported a history of rape or sexual molestation were ≥ 50 pounds overweight vs only 28% of age- and sex-matched controls without a history of abuse. Other studies have corroborated these findings.
Excess weight can serve an “adaptive function,” Dr. Sarwer noted. It can be a self-protective mechanism that “insulates” them from sexual advances by potential romantic partners or abusers. Some may find that, after weight loss, repressed memories of a sexual assault surface as a result of the newer, more “attractive” appearance. Feeling vulnerable in their thinner bodies, they may need to regard themselves as overweight to maintain that feeling of “protection.” Weight loss may also trigger memories, flashbacks, or nightmares, as people return to a weight at which they were abused.
Dissociation is another mechanism linking trauma with post–weight loss body dysmorphia, Supatra Tovar, PsyD, RD, a clinical psychologist and registered dietitian with a practice in California, told this news organization. Dissociation from the body is often a coping mechanism for dealing with an overwhelming traumatic experience.
Individuals with a history of depression, anxiety, or posttraumatic stress disorder have higher levels of body dysmorphia, both before and after weight loss. One study found that patients undergoing bariatric surgery who had some type of psychopathology and other psychological risk factors were significantly more likely to report body image concerns 3 months after the surgery. Body image concerns were also more common in patients with preoperative depression, current psychotropic medication use, and a history of outpatient therapy or psychotropic medication use.
“Depression, anxiety, and trauma play a role in how you see yourself and how you carry yourself,” Dr. Reddy said. “This is wrapped up in any type of psychopathology. Being depressed is like looking at yourself through a cloud. It’s the opposite of ‘rose-colored glasses’ and instead, looking at yourself through a negative lens.”
Diagnosis and Interventions
Some helpful tools to assess the presence and extent of weight dissatisfaction and body dysmorphia include the Eating Disorder Inventory — Body Dissatisfaction Subscale and the Body Shape Questionnaire. It’s also important to take into account “the extent to which people are invested in their appearance psychologically,” Dr. Sarwer advised. The AO subscale of the Multidimensional Body-Self Relations Questionnaire generally assesses this. The Body Image Quality of Life Inventory assesses how and to what extent the perceived body image affects the person’s quality of life.
Experts recommend cognitive behavioral therapy (CBT) as an evidence-based intervention for body image issues, including those following weight loss.
“There’s an extensive CBT body image therapy program specifically tailored to the needs of overweight and obese individuals,” Dr. Sarwer said. “We don’t ignore historical variables that may have contributed to the problem, like early bullying, but we encourage people to think about what’s going on in their day-to-day life today. We drill down not only into the maladaptive behaviors but also the cognition and beliefs that may be erroneous but underlie these behaviors.”
The aim of CBT is to “modify irrational and dysfunctional thoughts, emotions, and behaviors through techniques such as self-monitoring, cognitive structuring, psychoeducation, desensitization, and exposure and response prevention.” The program laid out in Cash’s body image workbook includes eight steps.

Weight Loss Doesn’t Automatically Equate With Happiness
Another realistic expectation runs counter to a common misperception that becoming thin will automatically translate into becoming happier. That’s not always the case, according to Dr. Tovar.
“If you haven’t worked deeply on addressing self-compassion and understanding that who you are at the core has nothing to do with your physical appearance, you can have an empty feeling once you’ve reached this point,” she said. “You still don’t know who you are and what you’re contributing to the world [because] you’ve been so focused on losing weight.”
Weight loss can also “unmask” questions about self-worth, even when receiving compliments about one’s “improved” appearance. “Praise and compliments after weight loss can be a double-edged sword,” Dr. Tovar observed. “You might think, ‘I wasn’t accepted or praised when I was overweight. The only way to be acceptable or validated is by losing weight, so I have to continue losing weight.’ ” This fuels fear of regaining the weight and can lead to continuing to see oneself as overweight, perhaps as a way to stay motivated to continue with weight loss. “Feeling that one’s value depends on remaining thin hampers body satisfaction,” she said.
Dr. Tovar, author of the book Deprogram Diet Culture: Rethink Your Relationship with Food, Heal Your Mind, and Live a Diet-Free Life, encourages people to shift the emphasis from weight loss to a holistic focus on self-worth and to explore obstacles to those feelings both before and after weight loss.
Endocrinologists and other medical professionals can help by not engaging in “weight and body shaming,” Dr. Tovar said.
She recommends physicians “encourage patients to tune in to their own bodies, helping them become more aware of how different foods affect their physical and emotional well-being.”
Set realistic expectations through “open, nonjudgmental conversations about the complexities of metabolism, weight, and health.”
Dr. Tovar advises rather than focusing on weight loss as the primary goal, physicians should focus on health markers such as blood glucose, energy levels, mental well-being, and physical fitness.
Prioritize “listening over lecturing.” Begin with empathy, asking questions such as “How do you feel about your health right now? What changes have you noticed in your body lately?” Doing this “creates space for the patient to express their concerns without feeling judged or shamed.”
Refer patients to a mental health professional when a patient exhibits signs of disordered eating or poor body image or when emotional factors are playing a significant role in the relationship with food and weight. “If a patient is caught in a cycle of dieting and weight gain, struggles with binge eating, or displays symptoms of depression or anxiety related to body, then psychological help is crucial.”
Ultimately, the goal of treatment “should be to provide a safe, supportive environment where patients can heal — not just physically but also emotionally and mentally,” Dr. Tovar added.
Dr. Tovar, Ms. Ekberg, and Dr. Reddy reported no relevant financial relationships. Dr. Sarwer received grant funding from the National Institute of Dental and Craniofacial Research and National Institute of Diabetes and Digestive and Kidney Diseases. He has consulting relationships with Novo Nordisk and Twenty30 Health. He is an associate editor for Obesity Surgery and editor in chief of Obesity Science & Practice.

Tirzepatide Shortage Resolved? FDA Says Yes, Compounders No
The agency wrote in a clarification aimed at compounders that Lilly said it can meet the “present and projected national demand” and that compounders are restricted from making the products.
Nevertheless, patients and prescribers may still see “intermittent localized supply disruptions as the products move through the supply chain,” the FDA noted.
The Alliance for Pharmacy Compounding (APC) responded swiftly, alerting its members and the public to the resolved shortage and stating that compounders “must immediately cease preparing and dispensing compounded copies” of the two drugs.
However, APC CEO Scott Brunner added it often takes a long time for FDA-approved versions of the drug to become widely available to wholesalers, hospitals, and clinics. Even after Lilly announced greater availability for the drugs, including in a new vial format for low doses, “for most pharmacies, they’re lucky to get two or three boxes of Zepbound a day from their wholesaler — for a patient waiting list that can number in the hundreds.”
“We have already heard this morning from APC members that they are unable to fill orders for their patients,” he said.
Furthermore, he contended, “I suspect plenty of patients taking compounded tirzepatide are going to be caught flat-footed by this. They are being cut off cold turkey, their prescription no longer fillable. They’ll need to get in to see their provider to get a new prescription, and that will take some time. It’s possible that so many patients presently taking compounded GLP-1s [glucagon-like peptide 1] will be eventually switched to the FDA-approved versions — if they can afford them, of course — that it will push tirzepatide injection back into shortage.”
Commenting on the shortage resolution, endocrinologist Beverly Tchang, MD, DABOM, an assistant professor of clinical medicine at Weill Cornell Medicine in New York City told this news organization, “we are not yet experiencing relief from the shortages, but I hope this resolves at least one barrier to access for our patients.”
“I don’t think it will create confusion,” she said. “Fortunately or unfortunately, patients and clinicians are adept by now with therapeutic transitions because we’ve been forced to do so whenever insurance withdraws coverage or a shortage recurs or a coupon expires. It’s obviously not ideal but patients are motivated and clinicians don’t give up.”
This news organization has previously reported on the impact of the shortages and how endocrinologists and obesity medicine specialists were handling them, in light of concerns about compounding pharmacies that may or may not be well founded.
Dr. Tchang declared that she is an adviser to Novo Nordisk.

Weight Loss After Anti-Obesity Medications Linked to Reduced Gout Risk
TOPLINE:
A higher rate of weight loss within 1 year of initiating orlistat is associated with lower risks for incident gout and recurrent gout flares in individuals with body mass index (BMI) > 25, particularly if they have obesity or high baseline serum urate levels.
METHODOLOGY:
- Researchers conducted a population-based cohort study using data from The Health Improvement Network in the United Kingdom to examine the association between weight loss rates after the initiation of anti-obesity medication (orlistat) and the risk for incident gout and recurrent gout flares in patients with overweight or obesity.
- The risk for incident gout was analyzed in 131,000 patients with overweight or obesity (mean age, 45 years; 77.3% women; mean BMI, 37.2) who did not have gout before initiating orlistat.
- The risk for recurrent gout flares was evaluated in 3847 individuals with overweight or obesity (mean age, 56.6 years; 29.4% women; mean BMI, 38.5), who had gout before initiating orlistat.
- Participants were divided into four groups based on their rate of weight loss during the first year of orlistat use: Weight gain or stable (< 2%), slow (2% to < 5%), moderate (5% to < 10%), and fast (≥ 10%).
- The primary outcome was incident gout, and the secondary outcome was the rate of recurrent gout flares during the 5-year follow-up period after initiating orlistat.
TAKEAWAY:
- The 5-year risk for incident gout was the lowest among patients in the fast weight loss group (1.2%) and highest among those in the weight gain or stable weight group (1.6%).
- The risk for incident gout was lower in the fast (hazard ratio [HR], 0.73; 95% CI, 0.62-0.86) and moderate (HR, 0.82; 95% CI, 0.72-0.92) weight loss groups than in the weight gain or stable weight group.
- Similarly, faster weight loss rates were linked to lower rates of recurrent gout flares, with risk ratios of 0.71 (95% CI, 0.60-0.84) and 0.83 (95% CI, 0.71-0.96) in the fast and moderate weight loss groups, respectively.
- This study found that .
IN PRACTICE:
“Pharmacologic treatments, such as orlistat, present an alternative strategy for managing overweight and obesity. Our study provides empirical evidence of a dose-response effect of weight loss after initiating orlistat within 1 year lowers the risk of incident gout and recurrent gout flares,” the authors wrote.
SOURCE:
This study was led by Jie Wei, PhD, Department of Orthopaedics, Xiangya Hospital, Central South University, Changsha, China, and was published online on September 19, 2024, in Arthritis & Rheumatology.
LIMITATIONS:
Despite adjustment for many variables, factors such as disease severity, exercise levels, and diet were not fully captured, which might have influenced the results. The lack of hospitalization data could have resulted in recurrent gout flares being underreported. The current study may have been subjected to bias due to potential exposure misclassification resulting from the timing of weight measurements and missing updated weight data.

Time-Restricted Eating Is Not a Metabolic Magic Bullet
This transcript has been edited for clarity.
One out of three American adults — about 100 million people in this country — have the metabolic syndrome. I’m showing you the official criteria here, but essentially this is a syndrome of insulin resistance and visceral adiposity that predisposes us to a host of chronic diseases such as diabetes, heart disease, and even dementia. 
The metabolic syndrome is, fundamentally, a lifestyle disease. There is a direct line between our dietary habits and the wide availability of carbohydrate-rich, highly processed foods, and the rise in the syndrome in the population.
A saying I learned from one of my epidemiology teachers comes to mind: “Lifestyle diseases require lifestyle reinterventions.” But you know what? I’m not so sure anymore.
I’ve been around long enough to see multiple dietary fads come and go with varying efficacy. I grew up in the low-fat era, probably the most detrimental time to our national health as food manufacturers started replacing fats with carbohydrates, driving much of the problem we’re faced with today.
But I was also around for the Atkins diet and the low-carb craze — a healthier approach, all things being equal. And I’ve seen variants of these: the paleo diet (essentially a low-carb, high-protein diet based on minimally processed foods) and the Mediterranean diet, which sought to replace some percentage of fats with healthier fats.
And, of course, there is time-restricted eating.
Time-restricted eating, a variant of intermittent fasting, has the advantage of being very simple. No cookbooks, no recipes. Eat what you want — but limit it to certain hours in the day, ideally a window of less than 10 hours, such as 8 a.m. to 6 p.m.
When it comes to weight loss, the diets that work tend to work because they reduce calorie intake. I know, people will get angry about this, but thermodynamics is not just a good idea, it’s the law.
But weight loss is not the only reason we need to eat healthier. What we eat can impact our health in multiple ways; certain foods lead to more atherosclerosis, more inflammation, increased strain on the kidney and liver, and can affect our glucose homeostasis.
So I was really interested when I saw this article, “Time-Restricted Eating in Adults With Metabolic Syndrome,” appearing in Annals of Internal Medicine October 1, which examined the effect of time-restricted eating on the metabolic syndrome itself. Could this lifestyle intervention cure this lifestyle disease?
In the study, 108 individuals, all of whom had the metabolic syndrome but not full-blown diabetes, were randomized to usual care — basically, nutrition education — vs time-restricted eating. In that group, participants were instructed to reduce their window of eating by at least 4 hours to achieve an 8- to 10-hour eating window. The groups were followed for 3 months.
Now, before we get to the results, it’s important to remember that the success of a lifestyle intervention trial is quite dependent on how well people adhere to the lifestyle intervention. Time-restricted eating is not as easy as taking a pill once a day.
The researchers had participants log their consumption using a smartphone app to confirm whether they were adhering to that restricted eating window.
Broadly speaking, they did. At baseline, both groups had an eating window of about 14 hours a day — think 7 a.m. to 9 p.m. The intervention group reduced that to just under 10 hours, with 10% of days falling outside of the target window.
Lifestyle change achieved, the primary outcome was the change in hemoglobin A1c at 3 months. A1c integrates the serum glucose over time and is thus a good indicator of the success of the intervention in terms of insulin resistance. But the effect was, honestly, disappointing.
Technically, the time-restricted-eating group had a greater A1c change than the control group — by 0.1 percentage points. On average, they went from a baseline A1c of 5.87 to a 3-month A1c of 5.75.
Other metabolic syndrome markers were equally lackluster: no difference in fasting glucose, mean glucose, or fasting insulin.
There was some weight change. The control group, which got that dietary education, lost 1.5% of body weight over the 3 months. The time-restricted-eating group lost 3.3% — about 7 pounds, which is reasonable.
With that weight loss came statistically significant, albeit modest improvements in BMI, body fat percentage, and LDL cholesterol.
Of interest, despite the larger weight loss in the intermittent-fasting group, there was no difference in muscle mass loss, which is encouraging.
Taken together, we can say that, yes, it seems like time-restricted eating can help people lose some weight. This is essentially due to the fact that people eat fewer calories when they do time-restricted eating, as you can see here.
But, in the end, this trial examined whether this relatively straightforward lifestyle intervention would move the needle in terms of metabolic syndrome, and the data are not very compelling for that.
This graph shows how many of those five factors for metabolic syndrome the individuals in this trial had from the start to the end. You see that, over the 3 months, seven people in the time-restricted-eating group moved from having three criteria to two or one — being “cured” of metabolic syndrome, if you will. Nine people in the standard group were cured by that definition. Remember, they had to have at least three to have the syndrome and thus be eligible for the trial. 
So If it just leads to weight loss by forcing people to consume less calories, then we need to acknowledge that we probably have better methods to achieve this same end. Ten years ago, I would have said that lifestyle change is the only way to end the epidemic of the metabolic syndrome in this country. Today, well, we live in a world of GLP-1 weight loss drugs. It is simply a different world now. Yes, they are expensive. Yes, they have side effects. But we need to evaluate them against the comparison. And so far, lifestyle changes alone are really no comparison.

Of interest, despite the larger weight loss in the intermittent-fasting group, there was no difference in muscle mass loss, which is encouraging.
Taken together, we can say that, yes, it seems like time-restricted eating can help people lose some weight. This is essentially due to the fact that people eat fewer calories when they do time-restricted eating, as you can see here.
But, in the end, this trial examined whether this relatively straightforward lifestyle intervention would move the needle in terms of metabolic syndrome, and the data are not very compelling for that.
This graph shows how many of those five factors for metabolic syndrome the individuals in this trial had from the start to the end. You see that, over the 3 months, seven people in the time-restricted-eating group moved from having three criteria to two or one — being “cured” of metabolic syndrome, if you will. Nine people in the standard group were cured by that definition. Remember, they had to have at least three to have the syndrome and thus be eligible for the trial.
So If it just leads to weight loss by forcing people to consume less calories, then we need to acknowledge that we probably have better methods to achieve this same end. Ten years ago, I would have said that lifestyle change is the only way to end the epidemic of the metabolic syndrome in this country. Today, well, we live in a world of GLP-1 weight loss drugs. It is simply a different world now. Yes, they are expensive. Yes, they have side effects. But we need to evaluate them against the comparison. And so far, lifestyle changes alone are really no comparison.

New Guidelines Emphasize Liver Care in T2D, Obesity
MADRID — Individuals with type 2 diabetes and/or obesity plus one or more metabolic risk factors are at a higher risk for metabolic dysfunction–associated steatotic liver disease (MASLD) with fibrosis and progression to more severe liver disease, stated new European guidelines that provide recommendations for diagnosis and management.
“The availability of improved treatment options underlines the need to identify at-risk individuals with MASLD early, as we now possess the tools to positively influence the course of the diseases, which is expected to prevent relevant clinical events,” stated the clinical practice guidelines, updated for the first time since 2016.
“Now we have guidelines that tell clinicians how to monitor the liver,” said Amalia Gastaldelli, PhD, research director at the Institute of Clinical Physiology of the National Research Council in Pisa, Italy, and a member of the panel that developed the guidelines.
Dr. Gastaldelli moderated a session focused on the guidelines at the annual meeting of the European Association for the Study of Diabetes (EASD). In an interview after the session, Dr. Gastaldelli, who leads a cardiometabolic risk research group, stressed the importance of the liver’s role in the body and the need for diabetes specialists to start paying more attention to this vital organ.
“It’s an important organ for monitoring because liver disease is silent, and the patient doesn’t feel unwell until disease is severe,” she said. “Diabetologists already monitor the eye, the heart, the kidney, and so on, but the liver is often neglected,” she said. A 2024 study found that the global pooled prevalence of MASLD among patients with type 2 diabetes was 65.33%.
Dr. Gastaldelli noted the importance of liver status in diabetes care. The liver makes triglycerides and very-low-density lipoprotein cholesterol, which are all major risk factors for atherosclerosis and cardiovascular disease (CVD), she said, as well as producing glucose, which in excess can lead to hyperglycemia.
The guidelines were jointly written by EASD, the European Association for the Study of the Liver, and the European Association for the Study of Obesity, and published in Diabetologia, The Journal of Hepatology, and Obesity Facts.
A Metabolic Condition
In the EASD meeting session, Dr. Gastaldelli discussed the reasons for, and implications of, shifting the name from nonalcoholic fatty liver disease (NAFLD) to MASLD.
“The name change focuses on the fact that this is a metabolic disease, while NAFLD had no mention of this and was considered stigmatizing by patients, especially in relation to the words ‘fatty’ and ‘nonalcoholic,’” she said.
According to the guidelines, MASLD is defined as liver steatosis in the presence of one or more cardiometabolic risk factor(s) and the absence of excess alcohol intake.
MASLD has become the most common chronic liver disease and includes isolated steatosis, metabolic dysfunction-associated steatohepatitis (MASH, previously NASH), MASH-related fibrosis, and cirrhosis.
In the overarching group of steatotic liver disease, a totally new intermediate category has been added: MASLD with moderate (increased) alcohol intake (MetALD), which represents MASLD in people who consume greater amounts of alcohol per week (140-350 g/week and 210-420 g/week for women and men, respectively).
The change in the nomenclature has been incremental and regional, Dr. Gastaldelli said. “The definition first changed from NAFLD to MAFLD, which recognizes the importance of metabolism in the pathophysiology of this disease but does not take into account alcohol intake. MAFLD is still used in Asia, Australasia, and North Africa, while Europe and the Americas have endorsed MASLD.”
Case-Finding and Diagnosis
Identifying MASLD cases in people at risk remains incidental, largely because it is a silent disease and is symptom-free until it becomes severe, said Dr. Gastaldelli.
The guideline recognizes that individuals with type 2 diabetes or obesity with additional metabolic risk factor(s) are at a higher risk for MASLD with fibrosis and progression to MASH.
Assessment strategies for severe liver fibrosis in MASLD include the use of noninvasive tests in people who have cardiometabolic risk factors, abnormal liver enzymes, and/or radiological signs of hepatic steatosis, particularly in the presence of type 2 diabetes or obesity or in the presence of one or more metabolic risk factors.
Dr. Gastaldelli noted that type 2 diabetes, metabolic syndrome, and obesity, including abdominal obesity identified by large waist circumference, are the major risk factors and should be warning signs.
“We need to consider abdominal obesity too — we’ve published data in relatively lean people, body mass index < 25, with MASH but without diabetes. Most of the patients accumulated fat viscerally and in the liver and had hypertriglyceridemia and hypercholesterolemia,” she said.
“The guidelines reflect this because the definition of MASLD includes steatosis plus at least one metabolic factor — waist circumference, for example, which is related to visceral fat, hyperlipidemia, or hyperglycemia. Of note, in both pharmacological and diet-induced weight loss, the decrease in liver fat was associated with the decrease in visceral fat.”
The noninvasive biomarker test, Fibrosis-4 (FIB-4) may be used to assess the risk for liver fibrosis. The FIB-4 index is calculated using a patient’s age and results of three blood tests — aspartate aminotransferase, alanine aminotransferase, and platelet count.
Advanced fibrosis (grade F3-F4) “is a major risk factor for severe outcomes,” said Dr. Gastaldelli. A FIB-4 test result below 1.3 indicates low risk for advanced liver fibrosis, 1.30-2.67 indicates intermediate risk, and above 2.67 indicates high risk.
“When fibrosis increases, then liver enzymes increase and the platelets decrease,” said Dr. Gastaldelli. “It is not a perfect tool, and we need to add in age because at a young age, it is prone to false negatives and when very old — false positives. It’s important to take a global view, especially if the patient has persistent high liver enzymes, but FIB-4 is low.”
“And if they have more than one metabolic risk factor, proceed with more tests, for example, transient elastography,” she advised. Imaging techniques such as transient elastography may rule out or rule in advanced fibrosis, which is predictive of liver-related outcomes.
“However, imaging techniques only diagnose steatosis and fibrosis, and right now, MASH can only be diagnosed with liver biopsy because we do not have any markers of liver inflammation and ballooning. In the future, noninvasive tests based on imaging and blood tests will be used to identify patients with MASH,” she added.
Management of MASLD — Lifestyle and Treatment
“Pharmacological treatments are designed for [patients] with MASH and fibrosis grade F2 or F3, but not MASLD,” Dr. Gastaldelli said. As such, lifestyle interventions are the mainstay of management — including weight loss, dietary changes, physical exercise, and low to no alcohol consumption. “Eating good-quality food and reducing calories are both important because the metabolism responds differently to different nutrients,” Dr. Gastaldelli said.
“In particular, the guidelines advise dietary management because some foods carry liver toxicity, for example, sugary foods with sucrose/fructose especially,” she said, adding that, “complex carbohydrates are less harmful than refined carbohydrates. Processed foods should be avoided if possible because they contain sugars, [as well as] saturated fats and hydrogenated fat, which is particularly bad for the liver. Olive oil is better than butter or margarine, which are rich in saturated fat, and fish and white meat are preferable.”
She added that a diet to help manage type 2 diabetes was not so dissimilar because sugar again needs to be reduced.
If a patient has severe obesity (and MASLD), data show that bariatric surgery is beneficial. “It not only helps weight loss, but it improves liver histology and has been shown to improve or resolve type 2 diabetes and reduce CVD risk. Importantly, regarding fibrosis, nutritional management after the bariatric surgery is the most important thing,” said Dr. Gastaldelli.
Optimal management of comorbidities — including the use of incretin-based therapies such as semaglutide or tirzepatide for type 2 diabetes or obesity, if indicated — is advised, according to the guidelines.
Glucagon-like peptide 1 receptor agonists (GLP-1 RAs) have been shown to have a beneficial effect on MASH, said Dr. Gastaldelli. “They have not shown effectiveness in the resolution of fibrosis, but this might take longer to manifest. However, if the medication is started early enough, it may prevent severe fibrosis. Significant weight loss, both with lifestyle and pharmacological treatment, should lead to an improvement in the liver too.”
There are currently no drugs available in Europe for the treatment of noncirrhotic MASH and severe fibrosis (stage ≥ 2). Resmetirom is the first approved MASH-targeted treatment in noncirrhotic MASH and significant liver fibrosis, with histological effectiveness on steatohepatitis and fibrosis, together with an acceptable safety and tolerability profile, but, for the moment, this agent is only available in United States.
Finally, turning to MASH-related cirrhosis, the guidelines advise adaptations of metabolic drugs, nutritional counseling, and surveillance for portal hypertension and hepatocellular carcinoma, as well as liver transplantation in decompensated cirrhosis.
After the session, this news organization spoke to Tushy Kailayanathan, MBBS BSc, medical director of the liver MRI company, Perspectum, who reviewed the limitations of the FIB-4 test. The FIB-4 test identifies those with advanced fibrosis in the liver, for example, patients with hepatitis C, she noted; however, “it performs worse in type 2 diabetic patients and in the elderly. There is little clinical guidance on the adjustment of FIB-4 thresholds needed for these high cardiometabolic risk groups. The priority patients are missed by FIB-4 because those individuals with early and active disease may not yet have progressed to advanced disease detected by FIB-4.”
These individuals are exactly those amenable to primary care prevention strategies, said Dr. Kailayanathan. Because of the nature of early and active liver disease in patients with high cardiometabolic risk, it would make sense to shift some diagnostic protocols into primary care.
“These individuals are exactly those amenable to primary care prevention strategies at annual diabetic review because they are likely to have modifiable cardiometabolic risk factors such as metabolic syndrome and would benefit from lifestyle and therapeutic intervention, including GLP-1 RAs and SGLT2is [sodium-glucose cotransporter-2 inhibitors],” she said. “Case-finding and detection of early-stage MASLD is a priority in diabetics, and there is an unmet need for accurate biomarkers to measure liver fat and inflammation early.”

FROM EASD 2024
Doctors Seek Additional Obesity Training in Wake of Obesity Patient Boom
Gitanjali Srivastava, MD, professor of medicine, pediatrics, and surgery, and medical director of obesity medicine at Vanderbilt University School of Medicine in Nashville, Tennessee, was nearly 10 years into practicing pediatric medicine when she graduated from the obesity medicine fellowship at Massachusetts General Hospital in Boston in 2013. “We were the very first sort of fellows to speak of then; there were no standards or curriculum,” she said.
Obesity was already epidemic, but stigma and bias were still pervasive in the medical community and within the public. After graduating, Dr. Srivastava spent months vying for a position with hospital CEOs. She traveled across the country explaining the specialty and its value, going into detail about the budget, business model, space requirement, and revenue potential of obesity medicine.
Today marks a very different era.
Obesity medicine is exploding. Patients are spilling into doctors’ offices looking for obesity treatment. Healthcare systems are seeking out obesity specialists and building metabolic health centers. Next month, another 2115 doctors from primary care, surgery, orthopedics, pediatrics, fertility, endocrinology, and beyond will sit for the 2024 exam. The once niche specialty is quickly becoming intertwined with most of modern medicine.
The Need to Treat
It’s no mystery that the rapid expansion of obesity medicine coincides with the US Food and Drug Administration’s approval of GLP-1 injections. The drugs’ radical weight loss properties have captured headlines and driven up patient demand. Meanwhile, doctors are finally able to offer effective treatment for a disease that affects 40% of US adults.
“We are finally treating it as a chronic disease, not as a lifestyle,” said Marcio Griebeler, MD, director of the obesity medicine fellowship at the Cleveland Clinic. And “I think it’s fulfilling for physicians,” he said.
For so long, the advice for obesity was about lifestyle. Move more, eat less, and harness willpower, “which really is a fallacy,” said Kimberly Gudzune, MD, MPH, an obesity medicine specialist and chief medical officer for the American Board of Obesity Medicine (ABOM) Foundation. For people with obesity, “your brain is operating differently,” she said. “Your body really is set up to work against you.”
Brianna Johnson-Rabbett, MD, medical director of the ABOM, told this news organization that with the advent of GLP-1s, “there’s a clearer recognition that obesity is a disease that needs to be treated like other diseases.” Some of that is thanks to clinical trial data showing that just as with other diseases such as high blood pressure or diabetes, obesity can be treated with medication and it resurges when the medication is stopped, she said.
Doctors don’t have to go looking for patients with obesity, dr. Griebeler added. Now that treatment options exist, they’re showing up in droves at the doctor’s office — all the doctors’ offices. In primary care, endocrinology, surgery, pediatrics — a wide variety of doctors are being asked about obesity drugs, Dr. Griebeler noted.
And while doctors are often just as excited as patients about the potential for treatment, many find themselves under-equipped when it comes to obesity. “More physicians are ... recognizing the value in treating this, and some are realizing, “Oh gosh, I never learned how to do this,” said Dr. Gudzune.
Information Patients Have Been Waiting For
Medical training has traditionally devoted minimal, if any, curriculum to obesity and metabolism. “To be honest, we didn’t really cover this at all in my training,” said Nina Paddu, MD, obesity medicine specialist at Maimonides Medical Center in New York City who finished her training only 2 years ago. “The guidance even in residency was ‘let’s send them to nutrition’ and ‘recommend exercising.’ ”
In addition to the medical education gap, until recently there was a “paucity of robust evidence,” Dr. Srivastava said. Leaders in the field wanted to establish standards and guidelines, but there wasn’t enough strong evidence on obesity and its treatments to build them, she said.
Only in the last 5 years or so has the evidence-based understanding of obesity’s pathophysiology truly accelerated: The brain’s driving roles, its interplay with hormones, and its interactions with other diseases. “We are just at the cusp of understanding all the different factors,” Dr. Gudzune said.
But already endocrinologists, surgeons, fertility specialists, gynecologists, and oncologists, to name a few, see the critical overlap with their own field. “Conditions were once suspected of being intertwined [with obesity], and now we have data to connect them,” Dr. Srivastava said. For example, there’s now data connecting semaglutide to a 20% reduction in cardiovascular events for people with obesity. That’s a game changer for multiple specialties, she told this news organization.
Getting Trained in Obesity Management
The recent uptick in obesity insights and increased patient need has doctors from every career stage seeking additional training.
The ABOM offers two board certification pathways: 60 hours of CME credits or a 12-month fellowship. Both paths require doctors to pass the board’s exam.
Many doctors incorporate the training into their existing practice. The CME credit pathway, especially, is designed to help get doctors up to speed without requiring them to upend their lives for a fellowship.
Dr. Srivastava said that the fellowship is more consuming and immersive. While it’s often younger doctors just out of training who apply to fellowship, every year, “I’m astonished at the number of talented physicians with clinical and research experience who want to immerse themselves in a fellowship experience.”
Some doctors return to their previous specialties after fellowship. But many will go on to take obesity medicine–specific roles or set aside clinic hours for obesity medicine. Their credentials are “really attractive to institutions, especially those looking to open up obesity medicine or weight management programs,” said Dr. Srivastava.
Dr. Paddu, who finished her obesity medicine fellowship this year, said there are a variety of obesity medicine jobs to choose from — far different from Dr. Srivastava’s job search 15 years ago. Dr. Paddu’s new role combines 2 days of primary care with 2 days devoted to obesity medicine and 1 day each week set aside for administrative work so she can build up the hospital’s new metabolic health clinic.
Still Not Enough Obesity Specialists
As with all things, rapid growth requires careful oversight. “Part of the responsibility of the board is to think critically of how the field is growing” and conduct ongoing monitoring, Dr. Gudzune said.
This is also why the board’s credentials are time-limited and must be recertified, Dr. Johnson-Rabbett added.
But even with the rise in certified doctors and obesity medicine positions, the 8263 doctors certified by ABOM are only a tiny fraction of US physicians. As a result, there’s genuine likelihood that many patients seeking GLP-1s or other obesity treatment don’t yet have access to the holistic care they need. Plus, doctors may still not have obesity expertise within their networks.
“The field has grown rapidly, but it’s still such a small field relative to the patient need,” said Dr. Gudzune.

Gitanjali Srivastava, MD, professor of medicine, pediatrics, and surgery, and medical director of obesity medicine at Vanderbilt University School of Medicine in Nashville, Tennessee, was nearly 10 years into practicing pediatric medicine when she graduated from the obesity medicine fellowship at Massachusetts General Hospital in Boston in 2013. “We were the very first sort of fellows to speak of then; there were no standards or curriculum,” she said.
Obesity was already epidemic, but stigma and bias were still pervasive in the medical community and within the public. After graduating, Dr. Srivastava spent months vying for a position with hospital CEOs. She traveled across the country explaining the specialty and its value, going into detail about the budget, business model, space requirement, and revenue potential of obesity medicine.

Popular Weight Loss Drugs Now for Patients With Cancer?
Demand for new weight loss drugs has surged over the past few years.
Led by the antiobesity drugs semaglutide (Wegovy) and tirzepatide (Zepbound), these popular medications — more commonly known as glucagon-like peptide 1 (GLP-1) agonists — have become game changers for shedding excess pounds.
Aside from obesity indications, both drugs have been approved to treat type 2 diabetes under different brand names and have a growing list of other potential benefits, such as reducing inflammation and depression.
While there’s limited data to support the use of GLP-1 agonists for weight loss in cancer, some oncologists have begun carefully integrating the antiobesity agents into care and studying their effects in this patient population.
The reason: Research suggests that obesity can reduce the effectiveness of cancer therapies, especially in patients with breast cancer, and can increase the risk for treatment-related side effects.
The idea is that managing patients’ weight will improve their cancer outcomes, explained Lajos Pusztai, MD, PhD, a breast cancer specialist and professor of medicine at Yale School of Medicine in New Haven, Connecticut.
Although Dr. Pusztai and his oncology peers at Yale don’t yet use GPL-1 agonists, Neil Iyengar, MD, and colleagues have begun doing so to help some patients with breast cancer manage their weight. Dr. Iyengar estimates that a few hundred — almost 40% — of his patients are on the antiobesity drugs.
“For a patient who has really tried to reduce their weight and who is in the obese range, that’s where I think the use of these medications can be considered,” said Dr. Iyengar, a breast cancer oncologist at Memorial Sloan Kettering Cancer Center in New York City.
Why GLP-1s in Cancer?
GLP-1 is a hormone that the small intestine releases after eating. GLP-1 agonists work by mimicking GLP-1 to trigger the release of insulin and reduce the production of glucagon — two processes that help regulate blood sugar.
These agents, such as Wegovy (or Ozempic when prescribed for diabetes), also slow gastric emptying and can make people feel fuller longer.
Zebound (or Mounjaro for type 2 diabetes) is considered a dual GLP-1 and glucose-dependent insulinotropic polypeptide agonist, which may enhance its weight loss benefits.
In practice, however, these drugs can increase nausea and vomiting from chemotherapy, so Dr. Iyengar typically has patients use them afterwards, during maintenance treatment.
Oncologists don’t prescribe the drugs themselves but instead refer patients to endocrinologists or weight management centers that then write the prescriptions. Taking these drugs involves weekly subcutaneous injections patients can administer themselves.
Endocrinologist Emily Gallagher, MD, PhD, of Mount Sinai Hospital in New York City, estimates she has prescribed the antiobesity drugs to a few hundred patients with cancer and, like Dr. Iyengar, uses the drugs during maintenance treatment with hormone therapy for breast cancer. She also has used these agents in patients with prostate and endometrial cancers and has found the drugs can help counter steroid weight gain in multiple myeloma.
But, to date, the evidence for using GPL-1 agonists in cancer remains limited and the practice has not yet become widespread.
Research largely comes down to a few small retrospective studies in patients with breast cancer receiving aromatase inhibitors. Although no safety issues have emerged so far, these initial reports suggest that the drugs lead to significantly less weight loss in patients with cancer compared to the general population.
Dr. Iyengar led one recent study, presented at the 2024 annual meeting of the American Society of Clinical Oncology, in which he and his team assessed outcomes in 75 women with breast cancer who received a GLP-1 agonist. Almost 80% of patients had diabetes, and 60% received hormone therapy, most commonly an aromatase inhibitor. Patients’ median body mass index (BMI) at baseline was 34 kg/m2 (range, 23-50 kg/m2).
From baseline, patients lost 6.2 kg, on average, or about 5% of their total body weight, 12 months after initiating GLP-1 therapy.
In contrast, phase 3 trials show much higher mean weight loss — about two times — in patients without cancer.
Another recent study also reported modest weight loss results in patients with breast cancer undergoing endocrine therapy. The researchers reported that, at 12 months, Wegovy led to 4.34% reduction in BMI, compared with a 14% change reported in the general population. Zebound, however, was associated with a 2.31% BMI increase overall — though some patients did experience a decrease — compared with a 15% reduction in the general population.
“These findings indicate a substantially reduced weight loss efficacy in breast cancer patients on endocrine therapy compared to the general population,” the authors concluded.
It’s unclear why the drugs appear to not work as well in patients with cancer. It’s possible that hormone therapy or metabolic changes interfere with their effectiveness, given that some cancer therapies lead to weight gain. Steroids and hormone therapies, for instance, often increase appetite, and some treatments can slow patients’ metabolism or lead to fatigue, which can make it harder to exercise.
Patients with cancer may need a higher dose of GLP-1 agonists to achieve similar weight loss to the general population, Dr. Iyengar noted.
However, Dr. Gallagher said, in her own experience, she hasn’t found the drugs to be less effective in patients with cancer, especially the newer agents, like Wegovy and Zepbound.
As for safety, Wegovy and Zepbound both carry a black box warning for thyroid C-cell tumors, including medullary thyroid carcinoma. (Recent research, however, has found that GLP-1 agonists do not increase thyroid cancer risk).
These antiobesity agents are also contraindicated in patients with a personal or family history of medullary thyroid carcinoma and in patients who have multiple endocrine neoplasia syndrome type 2, which is associated with medullary thyroid carcinoma.
Dr. Gallagher hasn’t seen any secondary tumors — thyroid or otherwise — in her patients with cancer, but she follows the labeling contraindications. Dr. Iyengar also noted that more recent and larger data sets have shown no impact on this risk, which may not actually exist, he said
Dr. Gallagher remains cautious about using GPL-1 agonists in patients who have had bariatric surgery because these agents can compound the slower gastric emptying and intestinal transit from surgery, potentially leading to gastrointestinal obstructions.
Looking ahead, GPL-1 manufacturers are interested in adding cancer indications to the drug labeling. Both Dr. Iyengar and Dr. Gallagher said their institutions are in talks with companies to participate in large, multicenter, global phase 3 trials.
Dr. Iyengar welcomes the efforts, not only to test the effectiveness of GPL-1 agonists in oncology but also to “nail down” their safety in cancer.
“I don’t think that there’s mechanistically anything that’s particularly worrisome,” and current observations suggest that these drugs are likely to be safe, Dr. Iyengar said. Even so, “GLP-1 agonists do a lot of things that we don’t fully understand yet.”
The bigger challenge, Dr. Iyengar noted, is that companies will have to show a sizable benefit to using these drugs in patients with cancer to get the Food and Drug Administration’s approval. And to move the needle on cancer-specific outcomes, these antiobesity drugs will need to demonstrate significant, durable weight loss in patients with cancer.
But if these drugs can do that, “I think it’s going to be one of the biggest advances in medicine and oncology given the obesity and cancer epidemic,” Dr. Iyengar said.
Dr. Iyengar has adviser and/or researcher ties with companies that make or are developing GPL-1 agonists, including AstraZeneca, Novartis, Gilead, and Pfizer. Dr. Gallagher is a consultant for Novartis, Flare Therapeutics, Reactive Biosciences, and Seagen.

Led by the antiobesity drugs semaglutide (Wegovy) and tirzepatide (Zepbound), these popular medications — more commonly known as glucagon-like peptide 1 (GLP-1) agonists — have become game changers for shedding excess pounds.
Aside from obesity indications, both drugs have been approved to treat type 2 diabetes under different brand names and have a growing list of other potential benefits, such as reducing inflammation and depression.
While there’s limited data to support the use of GLP-1 agonists for weight loss in cancer, some oncologists have begun carefully integrating the antiobesity agents into care and studying their effects in this patient population.
The reason: Research suggests that obesity can reduce the effectiveness of cancer therapies, especially in patients with breast cancer, and can increase the risk for treatment-related side effects.
The idea is that managing patients’ weight will improve their cancer outcomes, explained Lajos Pusztai, MD, PhD, a breast cancer specialist and professor of medicine at Yale School of Medicine in New Haven, Connecticut.
Although Dr. Pusztai and his oncology peers at Yale don’t yet use GPL-1 agonists, Neil Iyengar, MD, and colleagues have begun doing so to help some patients with breast cancer manage their weight. Dr. Iyengar estimates that a few hundred — almost 40% — of his patients are on the antiobesity drugs.
“For a patient who has really tried to reduce their weight and who is in the obese range, that’s where I think the use of these medications can be considered,” said Dr. Iyengar, a breast cancer oncologist at Memorial Sloan Kettering Cancer Center in New York City.
Why GLP-1s in Cancer?
GLP-1 is a hormone that the small intestine releases after eating. GLP-1 agonists work by mimicking GLP-1 to trigger the release of insulin and reduce the production of glucagon — two processes that help regulate blood sugar.
These agents, such as Wegovy (or Ozempic when prescribed for diabetes), also slow gastric emptying and can make people feel fuller longer.
Zebound (or Mounjaro for type 2 diabetes) is considered a dual GLP-1 and glucose-dependent insulinotropic polypeptide agonist, which may enhance its weight loss benefits.
In practice, however, these drugs can increase nausea and vomiting from chemotherapy, so Dr. Iyengar typically has patients use them afterwards, during maintenance treatment.
Oncologists don’t prescribe the drugs themselves but instead refer patients to endocrinologists or weight management centers that then write the prescriptions. Taking these drugs involves weekly subcutaneous injections patients can administer themselves.
Endocrinologist Emily Gallagher, MD, PhD, of Mount Sinai Hospital in New York City, estimates she has prescribed the antiobesity drugs to a few hundred patients with cancer and, like Dr. Iyengar, uses the drugs during maintenance treatment with hormone therapy for breast cancer. She also has used these agents in patients with prostate and endometrial cancers and has found the drugs can help counter steroid weight gain in multiple myeloma.
But, to date, the evidence for using GPL-1 agonists in cancer remains limited and the practice has not yet become widespread.
Research largely comes down to a few small retrospective studies in patients with breast cancer receiving aromatase inhibitors. Although no safety issues have emerged so far, these initial reports suggest that the drugs lead to significantly less weight loss in patients with cancer compared to the general population.
Dr. Iyengar led one recent study, presented at the 2024 annual meeting of the American Society of Clinical Oncology, in which he and his team assessed outcomes in 75 women with breast cancer who received a GLP-1 agonist. Almost 80% of patients had diabetes, and 60% received hormone therapy, most commonly an aromatase inhibitor. Patients’ median body mass index (BMI) at baseline was 34 kg/m2 (range, 23-50 kg/m2).
From baseline, patients lost 6.2 kg, on average, or about 5% of their total body weight, 12 months after initiating GLP-1 therapy.
In contrast, phase 3 trials show much higher mean weight loss — about two times — in patients without cancer.
Another recent study also reported modest weight loss results in patients with breast cancer undergoing endocrine therapy. The researchers reported that, at 12 months, Wegovy led to 4.34% reduction in BMI, compared with a 14% change reported in the general population. Zebound, however, was associated with a 2.31% BMI increase overall — though some patients did experience a decrease — compared with a 15% reduction in the general population.
“These findings indicate a substantially reduced weight loss efficacy in breast cancer patients on endocrine therapy compared to the general population,” the authors concluded.
It’s unclear why the drugs appear to not work as well in patients with cancer. It’s possible that hormone therapy or metabolic changes interfere with their effectiveness, given that some cancer therapies lead to weight gain. Steroids and hormone therapies, for instance, often increase appetite, and some treatments can slow patients’ metabolism or lead to fatigue, which can make it harder to exercise.
Patients with cancer may need a higher dose of GLP-1 agonists to achieve similar weight loss to the general population, Dr. Iyengar noted.
However, Dr. Gallagher said, in her own experience, she hasn’t found the drugs to be less effective in patients with cancer, especially the newer agents, like Wegovy and Zepbound.
As for safety, Wegovy and Zepbound both carry a black box warning for thyroid C-cell tumors, including medullary thyroid carcinoma. (Recent research, however, has found that GLP-1 agonists do not increase thyroid cancer risk).
These antiobesity agents are also contraindicated in patients with a personal or family history of medullary thyroid carcinoma and in patients who have multiple endocrine neoplasia syndrome type 2, which is associated with medullary thyroid carcinoma.
Dr. Gallagher hasn’t seen any secondary tumors — thyroid or otherwise — in her patients with cancer, but she follows the labeling contraindications. Dr. Iyengar also noted that more recent and larger data sets have shown no impact on this risk, which may not actually exist, he said
Dr. Gallagher remains cautious about using GPL-1 agonists in patients who have had bariatric surgery because these agents can compound the slower gastric emptying and intestinal transit from surgery, potentially leading to gastrointestinal obstructions.
Looking ahead, GPL-1 manufacturers are interested in adding cancer indications to the drug labeling. Both Dr. Iyengar and Dr. Gallagher said their institutions are in talks with companies to participate in large, multicenter, global phase 3 trials.
Dr. Iyengar welcomes the efforts, not only to test the effectiveness of GPL-1 agonists in oncology but also to “nail down” their safety in cancer.
“I don’t think that there’s mechanistically anything that’s particularly worrisome,” and current observations suggest that these drugs are likely to be safe, Dr. Iyengar said. Even so, “GLP-1 agonists do a lot of things that we don’t fully understand yet.”
The bigger challenge, Dr. Iyengar noted, is that companies will have to show a sizable benefit to using these drugs in patients with cancer to get the Food and Drug Administration’s approval. And to move the needle on cancer-specific outcomes, these antiobesity drugs will need to demonstrate significant, durable weight loss in patients with cancer.
But if these drugs can do that, “I think it’s going to be one of the biggest advances in medicine and oncology given the obesity and cancer epidemic,” Dr. Iyengar said.
Dr. Iyengar has adviser and/or researcher ties with companies that make or are developing GPL-1 agonists, including AstraZeneca, Novartis, Gilead, and Pfizer. Dr. Gallagher is a consultant for Novartis, Flare Therapeutics, Reactive Biosciences, and Seagen.

Five Essential Nutrients for Patients on GLP-1s
Fatigue, nausea, acid reflux, muscle loss, and the dreaded “Ozempic face” are side effects from using glucagon-like peptide 1 (GLP-1) receptor agonists (RAs) such as semaglutide or the dual glucose-dependent insulinotropic polypeptide (GIP)/GLP-1 RA tirzepatide to control blood sugar and promote weight loss.
But what I’ve learned from working with hundreds of patients on these medications, and others, is that most (if not all) of these side effects can be minimized by ensuring proper nutrition.
Setting patients up for success requires dietary education and counseling, along with regular monitoring to determine any nutritional deficiencies. Although adequate intake of all the macro and micronutrients is obviously important,
Protein
My patients are probably sick of hearing me talk about protein, but without the constant reinforcement, many of them wouldn’t consume enough of this macronutrient to maintain their baseline lean body mass. The recommended dietary allowance (RDA) for protein (0.8 g/kg bodyweight) doesn’t cut it, especially for older, obese patients, who need closer to 1.0-1.2 g/kg bodyweight to maintain their muscle mass. For example, for a 250-lb patient, I would recommend 114-136 g protein per day. This is equivalent to roughly 15 oz of cooked animal protein. It’s important to note, though, that individuals with kidney disease must limit their protein intake to 0.6-0.8 g/kg bodyweight per day, to avoid overtaxing their kidneys. In this situation, the benefit of increased protein intake does not outweigh the risk of harming the kidneys.
It’s often challenging for patients with suppressed appetites to even think about eating a large hunk of meat or fish, let alone consume it. Plus, eating more than 3-4 oz of protein in one meal can make some patients extremely uncomfortable, owing to the medication’s effect on gastric emptying. This means that daily protein intake must be spread out over multiple mini-meals.
For patients who need more than 100 g of protein per day, protein powders and premade protein shakes can provide 20-30 g protein to fill in the gaps. Although I always try to promote food first, protein supplements have been game changers for my patients, especially those who find solid food less appealing on the medication, or those who avoid animal protein.
Clinicians should have their patients monitor changes in their lean body mass using a dual-energy x-ray absorptiometry scan or a bioelectrical impedance scale; this can be a helpful tool in assessing whether protein intake is sufficient.
Fiber
Even my most knowledgeable and compliant patients will experience some constipation. Generally speaking, when you eat less, you will have fewer bowel movements. Combine that with delayed gastric emptying and reduced fiber intake, and you have a perfect storm. Many patients are simply not able to get in the recommended 25-35 g fiber per day through food, because fibrous foods are filling. If they are prioritizing the protein in their meal, they will not have enough room for all the vegetables on their plate.
To ensure that patients are getting sufficient fiber, clinicians should push consumption of certain vegetables and fruits, such as carrots, broccoli, Brussels sprouts, raspberries, blackberries, and apples, as well as beans and legumes. (Salads are great, but greens like spinach are not as fibrous as one might think.) If the fruit and veggie intake isn’t up to par, a fiber supplement such as psyllium husk can provide an effective boost.
Vitamin B12
Use of these medications is associated with a reduction in vitamin B12 levels, in part because delayed gastric emptying may affect B12 absorption. Low dietary intake of B12 while on the medications can also be to blame, though. The best food sources are animal proteins, so if possible, patients should prioritize having fish, lean meat, eggs, and dairy daily.
Vegetarians and vegans, who are at an increased risk for deficiency, can incorporate nutritional yeast, an excellent source of vitamin B12, into their daily routine. It is beneficial for patients to get blood work periodically to check on B12 status, because insufficient B12 can contribute to the fatigue patients experience while on the medication.
Calcium
Individuals should have calcium on their radar, because weight loss is associated with a decrease in bone mineral density. Adequate intake of the mineral is crucial for optimal bone health, particularly among postmenopausal women and those who are at risk of developing osteoporosis. The RDA for calcium is 1000-1200 mg/d, which an estimated 50% of obese individuals do not take in.
Although dairy products are well-known for being rich in calcium, there are other great sources. Dark green leafy vegetables, such as cooked collard greens and spinach, provide nearly 300 mg per cup. Tofu and sardines are also calcium powerhouses. Despite the plethora of calcium-rich foods, however, some patients may need a calcium supplement.
Vitamin D
Vitamin D deficiency or insufficiency is common among individuals with obesity, so even before these patients start the medications, supplementation may be warranted. The vitamin’s role in promoting calcium absorption, as well as in bone remodeling, make adequate intake essential for patients experiencing significant weight loss.
Clinicians should emphasize regular consumption of fatty fish, such as salmon, as well as eggs, mushrooms, and vitamin D–fortified milks. But unfortunately, that’s where the list of vitamin D–rich foods ends, so taking a vitamin D supplement will be necessary for many patients.
Regularly monitoring patients on GLP-1 RAs through blood work to check vitamin levels and body composition analysis can be helpful in assessing nutritional status while losing weight. Clinicians can also encourage their patients to work with a registered dietitian who is familiar with these medications, so they can develop optimal eating habits throughout their health journey.

Walking App Works Only if Users Think It Does
TOPLINE:
Apps designed to increase physical activity may be useful in increasing daily step counts for users who believe the intervention beneficial, but not for those who do not. The app’s effectiveness is notably influenced by how users perceive its utility.
METHODOLOGY:
- Researchers conducted a randomized controlled trial from February 2021 to May 2022 to evaluate the effectiveness of SNapp, an adaptive app designed to promote walking through tailored coaching content.
- Overall, 176 adults (76% women; mean age, 56 years) were randomly assigned to use the app plus tailored coaching content (SNapp group; n = 87) or only the step counter app (control group; n = 89).
- SNapp’s coaching content provided personalized feedback on step counts and recommendations for increasing walking, while also considering individual preferences for behavior change techniques.
- The primary outcome was the daily step count recorded by the app, which was updated on an hourly basis in a database over an intervention period of 12 months.
- Perceptions of ease of use and usefulness were assessed to determine their effect on the effectiveness of the app.
TAKEAWAY:
- Intervention group participants used the app nearly 30% of days, while those using the app alone showed almost identical use.
- The SNapp intervention did not significantly affect the step counts on average over time (B, −202.30; 95% CI, −889.7 to 485.1).
- Perceived usefulness significantly moderated the intervention effect of SNapp (B, 344.38; 90% CI, 40.4-648.3), but perceived ease of use did not (B, 38.60; 90% CI, −276.5 to 353.7).
- Among participants with a high perceived usefulness, the SNapp group had a higher median step count than the control group (median difference, 1260 steps; 90% CI, −3243.7 to 1298.2); however, this difference was not statistically significant.
IN PRACTICE:
“This study shows that perceived usefulness is also an important factor influencing behavioral effects. Hence, it is essential for apps to be perceived as useful to effectively improve users’ activity levels,” the authors wrote.
SOURCE:
The study was led by Anne L. Vos, PhD, of the Amsterdam School of Communication Research at the University of Amsterdam, in the Netherlands. It was published online on September 16, 2024, in the American Journal of Preventive Medicine.
LIMITATIONS:
The study’s recruitment strategy primarily attracted highly educated individuals, limiting generalizability. The app’s accuracy in measuring steps could be improved, as it sometimes underestimated step counts. Researchers also were unable to check if participants read messages from coaches.
DISCLOSURES:
The study was supported by grants from the Dutch Heart Foundation and the Netherlands Organisation for Health Research and Development. No relevant conflicts of interest were disclosed by the authors.

AACR Cancer Progress Report: Big Strides and Big Gaps
The AACR’s 216-page report — an annual endeavor now in its 14th year — focused on the “tremendous” strides made in cancer care, prevention, and early detection and highlighted areas where more research and attention are warranted.
One key area is funding. For the first time since 2016, federal funding for the National Institutes of Health (NIH) and National Cancer Institute (NCI) decreased in the past year. The cuts followed nearly a decade of funding increases that saw the NIH budget expand by nearly $15 billion, and that allowed for a “rapid pace and broad scope” of advances in cancer, AACR’s chief executive officer Margaret Foti, MD, PhD, said during a press briefing.
These recent cuts “threaten to curtail the medical progress seen in recent years and stymie future advancements,” said Dr. Foti, who called on Congress to commit to funding cancer research at significant and consistent levels to “maintain the momentum of progress against cancer.”
Inside the Report: Big Progress
Overall, advances in prevention, early detection, and treatment have helped catch more cancers earlier and save lives.
According to the AACR report, the age-adjusted overall cancer death rate in the United States fell by 33% between 1991 and 2021, meaning about 4.1 million cancer deaths were averted. The overall cancer death rate for children and adolescents has declined by 24% in the past 2 decades. The 5-year relative survival rate for children diagnosed with cancer in the US has improved from 58% for those diagnosed in the mid-1970s to 85% for those diagnosed between 2013 and 2019.
The past fiscal year has seen many new approvals for cancer drugs, diagnostics, and screening tests. From July 1, 2023, to June 30, 2024, the Food and Drug Administration (FDA) approved 15 new anticancer therapeutics, as well as 15 new indications for previously approved agents, one new imaging agent, several artificial intelligence (AI) tools to improve early cancer detection and diagnosis, and two minimally invasive tests for assessing inherited cancer risk or early cancer detection, according to the report.
“Cancer diagnostics are becoming more sophisticated,” AACR president Patricia M. LoRusso, DO, PhD, said during the briefing. “New technologies, such as spatial transcriptomics, are helping us study tumors at a cellular level, and helping to unveil things that we did not initially even begin to understand or think of. AI-based approaches are beginning to transform cancer detection, diagnosis, clinical decision-making, and treatment response monitoring.”
The report also highlights the significant progress in many childhood and adolescent/young adult cancers, Dr. LoRusso noted. These include FDA approvals for two new molecularly targeted therapeutics: tovorafenib for children with certain types of brain tumor and repotrectinib for children with a wide array of cancer types that have a specific genetic alteration known as NTRK gene fusion. It also includes an expanded approval for eflornithine to reduce the risk for relapse in children with high-risk neuroblastoma.
“Decades — decades — of basic research discoveries, have led to these clinical breakthroughs,” she stressed. “These gains against cancer are because of the rapid progress in our ability to decode the cancer genome, which has opened new and innovative avenues for drug development.”
The Gaps
Even with progress in cancer prevention, early detection, and treatment, cancer remains a significant issue.
“In 2024, it is estimated that more than 2 million new cases of cancer will be diagnosed in the United States. More than 611,000 people will die from the disease,” according to the report.
The 2024 report shows that incidence rates for some cancers are increasing in the United States, including vaccine-preventable cancers such as human papillomavirus (HPV)–associated oral cancers and, in young adults, cervical cancers. A recent analysis also found that overall cervical cancer incidence among women aged 30-34 years increased by 2.5% a year between 2012 and 2019.
Furthermore, despite clear evidence demonstrating that the HPV vaccine reduces cervical cancer incidence, uptake has remained poor, with only 38.6% of US children and adolescents aged 9-17 years receiving at least one dose of the vaccine in 2022.
Early-onset cancers are also increasing. Rates of breast, colorectal, and other cancers are on the rise in adults younger than 50 years, the report noted.
The report also pointed to data that 40% of all cancer cases in the United States can be attributed to preventable factors, such as smoking, excess body weight, and alcohol. However, our understanding of these risk factors has improved. Excessive levels of alcohol consumption have, for instance, been shown to increase the risk for six different types of cancer: certain types of head and neck cancer, esophageal squamous cell carcinoma, and breast, colorectal, liver, and stomach cancers.
Financial toxicity remains prevalent as well.
The report explains that financial hardship following a cancer diagnosis is widespread, and the effects can last for years. In fact, more than 40% of patients can spend their entire life savings within the first 2 years of cancer treatment. Among adult survivors of childhood cancers, 20.7% had trouble paying their medical bills, 29.9% said they had been sent to debt collection for unpaid bills, 14.1% had forgone medical care, and 26.8% could not afford nutritious meals.
For young cancer survivors, the lifetime costs associated with a diagnosis of cancer are substantial, reaching an average of $259,324 per person.
On a global level, it is estimated that from 2020 to 2050, the cumulative economic burden of cancer will be $25.2 trillion.
The Path Forward
Despite these challenges, Dr. LoRusso said, “it is unquestionable that we are in a time of unparalleled opportunities in cancer research.
“I am excited about what the future holds for cancer research, and especially for patient care,” she said.
However, funding commitments are needed to avoid impeding this momentum and losing a “talented and creative young workforce” that has brought new ideas and new technologies to the table.
Continued robust funding will help “to markedly improve cancer care, increase cancer survivorship, spur economic growth, and maintain the United States’ position as the global leader in science and medical research,” she added.
The AACR report specifically calls on Congress to:
- Appropriate at least $51.3 billion in fiscal year 2025 for the base budget of the NIH and at least $7.934 billion for the NCI.
- Provide $3.6 billion in dedicated funding for Cancer Moonshot activities through fiscal year 2026 in addition to other funding, consistent with the President’s fiscal year 2025 budget.
- Appropriate at least $472.4 million in fiscal year 2025 for the CDC’s Division of Cancer Prevention to support comprehensive cancer control, central cancer registries, and screening and awareness programs for specific cancers.
- Allocate $55 million in funding for the Oncology Center of Excellence at FDA in fiscal year 2025 to provide regulators with the staff and tools necessary to conduct expedited review of cancer-related medical products.
By working together with Congress and other stakeholders, “we will be able to accelerate the pace of progress and make major strides toward the lifesaving goal of preventing and curing all cancers at the earliest possible time,” Dr. Foti said. “I believe if we do that ... one day we will win this war on cancer.”

The AACR’s 216-page report — an annual endeavor now in its 14th year — focused on the “tremendous” strides made in cancer care, prevention, and early detection and highlighted areas where more research and attention are warranted.
