New Studies Confirm Weight Regain After GLP-1 Treatment Ends

For millions of patients, GLP-1 medications like Ozempic, Wegovy, and Zepbound have offered a miraculous solution to obesity. However, a comprehensive new analysis led by the University of Oxford delivers a sobering warning: the benefits are largely temporary unless patients commit to the drugs for life.

Researchers reviewed data from 37 studies involving over 9,000 participants and found that stopping these medications triggers a swift reversal of progress,. On average, patients are projected to return to their pre-treatment weight within just 1.7 years of ceasing the medication. Vital improvements in heart health, such as blood pressure and cholesterol levels, are expected to disappear even faster, returning to baseline levels within 1.4 years.

The study highlights that weight returns more aggressively after stopping drugs than after ending behavioral diet programs. While general weight-loss drugs saw a regain of roughly one pound per month, patients stopping potent GLP-1s like semaglutide (Ozempic) and tirzepatide (Zepbound) regained weight nearly twice as fast, averaging 1.8 pounds per month.

Why the rapid rebound? Biologically, the body reacts to the weight loss as a "deficiency," ramping up the hunger hormone ghrelin while the metabolic rate drops. Behaviorally, patients on these drugs may lose weight without developing the dietary "skills" required to keep it off, unlike those in lifestyle programs.

The implications are significant for healthcare systems and patients alike. In Denmark, real-world data shows that 52% of users quit Wegovy within a year, often due to high costs or side effects. With out-of-pocket costs exceeding $4,000 annually for some, indefinite treatment is financially unsustainable for many.

As lead author Dr. Sam West notes, these findings do not suggest the medicines fail, but rather that obesity is a chronic, relapsing condition requiring long-term management rather than a short-term fix,. Experts now suggest that unless patients are prepared for a lifetime prescription or alternative interventions like bariatric surgery, the weight—and its associated health risks—will likely return.
