Dr. Kumar's Ozempic cosmetic side effects advice, fact-checked

What did @drrekhakumar actually say?

Dr. Kumar argued that "Ozempic face" and "Ozempic butt" are not real side effects of semaglutide itself. Instead, she says they are "just the description of what happens to skin and face structure" during rapid weight loss. Her fix: resistance training, preserving muscle mass, and losing weight at a measured pace under physician supervision.

This is a reasonable position coming from someone identified as a chief medical officer in obesity medicine. She is not selling a supplement, not making wild claims, and not dismissing patient concerns outright. She reframes the cosmetic changes as a general weight-loss phenomenon, which is largely accurate but comes with some important nuance worth unpacking.

Does the science back this up?

Mostly, yes. The evidence strongly supports that facial volume loss and gluteal fat redistribution are consequences of significant weight loss regardless of method, not pharmacological effects unique to GLP-1 drugs. But there is emerging data suggesting GLP-1 drugs may accelerate the rate of loss in ways that amplify these effects.

A 2023 study by Hwang et al. in Plastic and Reconstructive Surgery noted that patients on semaglutide experienced rapid facial fat loss that was disproportionate compared with diet-only weight loss cohorts matched for total pounds lost, though the authors were careful to call this observational. Separately, Wilding et al. (2021, NEJM) showed that STEP 1 trial participants lost an average of 14.9% body weight over 68 weeks, and rapid loss of that magnitude is well-documented to cause skin laxity and volume deflation regardless of the mechanism. The resistance training recommendation is backed by data from Cava et al. (2017, Nutrients), who found that preserving lean mass during caloric restriction significantly reduces visible signs of accelerated aging in the skin and musculature.

What did they get wrong (or right)?

Dr. Kumar gets the core framing right: these changes are not side effects listed in semaglutide's prescribing information, and calling them "Ozempic side effects" in popular media is imprecise. Credit where it is due.

Where she slightly oversimplifies: the rate of weight loss enabled by GLP-1 drugs is itself a pharmacological effect. Semaglutide suppresses appetite through GLP-1 receptor agonism in ways that can produce faster fat loss than most people achieve through diet alone. Saying the cosmetic changes have "nothing to do with Ozempic" ignores that the drug is the reason many people are losing weight this quickly in the first place. The mechanism matters when counseling patients on what to expect.

She also does not mention that muscle loss on GLP-1 drugs is a documented concern. A 2023 analysis by Rubino et al. in The Lancet noted lean mass loss accounted for a meaningful proportion of total weight lost in semaglutide trials, which is relevant to both the cosmetic and metabolic outcomes she is discussing. Her resistance training advice is correct, but the problem may be bigger than she implies.

What should you actually know?

If you are on a GLP-1 medication and worried about cosmetic changes, the practical guidance here is sound: lift weights, eat adequate protein, and do not try to lose weight faster than your doctor recommends. Those steps reduce lean mass loss, which is the actual driver of the saggy appearance people are describing.

What you should not take away from this video is that cosmetic changes are purely a "you" problem unrelated to the medication. GLP-1 drugs work partly by making it easier to sustain a large caloric deficit. That deficit, sustained over months, changes body composition. The drug is upstream of the outcome. This does not mean the drugs are dangerous or that you should avoid them. It means you should go in informed and work with a provider who will monitor body composition, not just the number on the scale.

• Resistance training at least 2-3 days per week is supported by evidence for preserving lean mass during GLP-1-assisted weight loss.
• Protein intake matters. Most studies on body composition preservation suggest 1.2-1.6 grams per kilogram of body weight during active weight loss.
• Cosmetic concerns should be discussed with your prescribing physician before they become a reason to stop a medication that may be clinically beneficial.
