Publicly doctors say all of the things you'd expect a group with heavy state and federal scrutiny to say about weight loss drugs such as Ozempic and Wegovy but privately they say things like 'people will be on it for the rest of their lives.'

Because a drug does not change lifestyle. To reduce risk of obesity co-morbidities, losing weight is the best way, but it can be daunting. If it took you five years to put on 20 pounds by eating too much, it will take you five years to lose it by reducing the same amount of calories you ate to get there. It can be miserable if your mindset isn't correct. Products like GLP-1s simply make you uninterested in eating. They are a great way to drop weight quickly, and if you then stay at an energy-balance plateau, where your metabolism and exercise levels are, you will be fine. If you go right back to eating half a pizza or the Whole Foods Organic Big Caesar Salad, your fat will return.

GLP-1s have been around long enough that there is good data and a new paper did a systematic review and meta‑analysis of 48 studies, including 36 randomized controlled trials, and then six clinical trials, comprised of over 3,200 humans, that followed people for up to a year were used to  
model the trajectory of weight regain beyond that.

Their model believes that people who stop taking the drugs regain weight rapidly, up to 60 percent of it, and then plateau at 75 percent of the original weight loss.  If you are a 200-pound man and lost 10 pounds, keeping two pounds off and gaining Ozempic Face is probably not worth the money you spent, but if you are at 300 and lost 80, you are a lot less likely to regain 60 of that back and even 20 pounds less is a sharp upward curve in lowered risk factors.


Fitted trajectories of weight regain following cessation of glucagon-like peptide 1 receptor agonists (GLP-1RAs), based on clinical trial data. Regression was conducted with an exponential recovery function. Semaglutide was given in STEP 1, STEP 4, and STEP 10; tirzepatide was given in SURMOUNT-1 and SURMOUNT-4; liraglutide was given in SCALE Obesity. The black line indicates the pooled fitted trajectory.

These are population-level statistics that got fed up into a computer simulation. Like BMI or any other epidemiological claim, such as salt recommendations or beliefs about so-called "ultra-processed" foods, it may have zero clinical relevance to you. If you take them and kickstart your health by losing weight and like how you look and feel, you may not go back to previous eating habits you had when you were young.

If your doctor says try it, do so. 

Some food consumption is behavioral - maybe you like watching movies and got used to eating a bag of Doritos so you associate good movies with delicious snacks - and while you were on the weight-loss drugs your brain reset previous those psychological appetite hooks.

The best way to mitigate risk of weight regain is to also exercise. You will see less weight loss, because muscle weighs a lot more than fat, but muscle burns energy while fat just lays there, so you can then have some pizza without any risk at all. If you only 'lost' 10 pounds because you lost 20 in fat and added 10 in muscle, you will look and feel good.
