Understanding weight regain after stopping GLP-1 agonists
When patients discontinue GLP-1 receptor agonists like Mounjaro and Wegovy, weight regain is frequently observed. This phenomenon has been well-documented in clinical trials and real-world studies.
Why Does Weight Come Back?
The primary reason for weight regain lies in how GLP-1 agonists function. These medications work by:
*Modulating appetite-regulating hormones.
*Lowering the body’s weight set point.
*Enhancing satiety and reducing caloric intake.
When treatment stops, these hormonal changes often reverse. As a result, hunger increases, and the body’s natural weight regulation mechanisms resume, often leading to significant weight regain.
Clinical Evidence:
*In the STEP 1 trial, participants who stopped taking semaglutide regained approximately two-thirds of the weight they had lost within a year.
*The SURMOUNT-4 study revealed similar trends with Mounjaro, showing a 14% weight regain within a year of discontinuation.
*These studies highlight the chronic nature of obesity and the challenges of sustaining weight loss once pharmacological support is withdrawn.

The science behind weight regain and maintenance

Hormonal Changes and Set Points
GLP-1 agonists significantly influence the brain’s appetite centers by mimicking the hormone glucagon-like peptide-1 (GLP-1). This helps reduce appetite and increase feelings of fullness. Discontinuing the medication means that these appetite-suppressing signals weaken, leading to increased food cravings.
Additionally, cardiometabolic improvements seen during treatment often revert, including:
*Elevated blood pressure.
*Increased glucose levels.
*Higher cholesterol markers.
Why Lifestyle Alone May Not Be Enough
Weight regain isn’t solely due to lifestyle lapses. The body’s biological drive to restore its previous weight can be powerful. Therefore, combining lifestyle changes with continued medical support is crucial for many patients.
