A recent study suggests that patients who discontinue popular slimming jabs like Wegovy and Mounjaro may regain lost weight far faster than those who halt traditional diet and exercise programs.
Published data in a leading health publication demonstrates that while overweight individuals often shed a large proportion of their body weight while undergoing treatment, the weight is regained at an average rate of nearly a kilo each month after stopping.
"People using these medications need to be cognizant of the danger of quick rebound weight gain when the medication ends," cautioned expert Dr. Susan Jebb.
This pace of regain means a reversion to pre-treatment mass within about one and a half years.
Weighing Treatments
The study, which examined dozens of trials involving thousands of participants, contrasted the effects of GLP-1 agonists with conventional dieting.
Scientists emphasize that individuals who shed pounds through dieting usually see a less rapid creep back—approximately 100 grams monthly—once they finish.
Understanding the Rapid Rebound
Nutrition scientists suggest the mechanism of the drugs explains the heightened regain.
These medications copy a natural hormone called glucagon-like peptide-1, which moderates hunger.
"Sustained high doses of the hormone levels far above than the body's typical production could lead to the system to produce less of its endogenous hormone, and may also lessen responsiveness to its effects," noted Dr. Adam Collins, a nutrition researcher.
"Stopping of this medication results in hunger is unsuppressed, making overeating far more likely."
A Lifelong Disease?
Medical guidelines recommend the jabs for individuals with weight-linked medical conditions, accompanied by recommended diet and exercise modifications.
Many experts say that, given the high risk of relapse, the therapy should be considered long-term.
This perspective is reinforced by drug manufacturers, who state that the findings "emphasize the long-term nature of obesity," akin to managing diseases like hypertension.
User Experiences
Users who have come off the medication explain a powerful return of hunger.
"It was like a switch that goes on and you become ravenous," described an individual.
This difficulty is compounded if patients have not established sustainable lifestyle or habit changes during treatment.
Growing Use
Recent estimates show that millions of adults in the UK have used weight-loss jabs in the past year, with interest remaining high.
- Adoption is greater among women than men.
- The 40s and 50s age group shows the greatest level of interest.
- A large proportion obtain the drugs through private prescriptions rather than public health services.
Finally, researchers caution that while the jabs are potent agents for weight loss, they are not a standalone cure and maintained weight loss likely depends on integrated lifestyle support.
