In short
Weight regain is the return of lost weight, driven by hormones that defend the body’s previous weight and by a lower energy use after weight loss. One year after stopping semaglutide, people in the STEP 1 extension regained two thirds of the weight they had lost. Weight regain reflects a chronic disease, not a lack of discipline.
Condition Overview
What is weight regain?
Weight regain is regaining weight after a successful loss, typically within 1 to 5 years. Weight regain is common with every treatment: diet, exercise, medicines, balloons and, less often, surgery.
Why does weight come back after weight loss?
Weight comes back because the body defends a set point of fat mass. After weight loss, hunger hormones rise, fullness hormones fall and energy use drops beyond what the lower weight explains. About 300 minutes of moderate activity a week, 5 hours, counter these effects, according to clinical guidance.
What happens after stopping weight loss injections?
After stopping weekly semaglutide 2.4 mg, participants in the STEP 1 extension regained two thirds of their weight loss within 1 year: from a loss of 17.3 percent at week 68 to a net loss of 5.6 percent at week 120 (Diabetes, Obesity and Metabolism, 2022). Blood pressure, blood sugar and blood fats moved back towards baseline as well.
Who keeps weight off?
People who keep weight off share regular self-weighing, a larger early weight loss, regular follow-up, a reduced-calorie diet and about 1 hour of activity a day. Resistance training and enough protein preserve muscle, which protects energy use.
Weight regain in Dubai and the UAE
Why is keeping weight off harder in the UAE?
The national UAE health survey 2024 to 2025 found obesity in 22.4 percent of adults, more than 1 in 5, high blood pressure in 25.9 percent, raised blood sugar in 12.5 percent and too little physical activity in 59.1 percent (MOHAP survey, reported by WAM).
Summer heat limits outdoor activity for months, so the activity plan moves indoors or to early mornings.
Dr Felix treats within the scope of his Dubai Health Authority licence. When a case needs a specialist view, for example suspected Cushing’s syndrome, a severe eating disorder or weight loss surgery, the decision is made together with an endocrinologist, psychiatrist or bariatric surgeon.

Why Early Treatment Can Matter
Acting early on weight regain stops a small regain before it becomes a full return, and a maintenance plan before stopping a medicine prevents much of the rebound.
