New research indicates that patients who come off blockbuster slimming jabs like Wegovy and Mounjaro can put back on reduced body mass much more quickly than those who stop traditional diet and exercise plans.
Research printed in a prominent health publication demonstrates that while overweight individuals frequently drop about a fifth of their body weight while on the medication, the weight returns at an average rate of 0.8 kg per month after stopping.
"Users using such medications should be aware of the potential of fast rebound weight gain when the therapy concludes," warns expert Dr. Susan Jebb.
Such speed of recovery implies a reversion to pre-treatment weight in about one and a half years.
Analyzing Approaches
The study, which looked at dozens of studies involving thousands of participants, compared the outcomes of these new drugs with older methods.
Researchers note that individuals who shed pounds through diet and exercise typically have a less rapid creep back—perhaps 0.1 kg a month—once they finish.
The Reason for the Quick Regain
Nutrition scientists suggest the mechanism of the injections explains the accelerated rebound.
These medications copy a body's own chemical called GLP-1, which moderates feelings of fullness.
"Artificially providing GLP-1 levels far above than the body's typical production might result in the system to produce less of its endogenous GLP-1, and could lessen responsiveness to its actions," explained Dr. Adam Collins, a dietetics specialist.
"Stopping of this hormone supplement results in appetite is unsuppressed, making binge eating far more likely."
A Chronic Condition?
Medical guidelines suggest the jabs for individuals with weight-linked medical conditions, alongside recommended diet and exercise modifications.
A number of clinicians argue that, considering the significant potential of weight regain, the therapy should be considered ongoing.
This perspective is supported by drug manufacturers, who state that the results "underscore the long-term character of excess weight," akin to managing diseases like diabetes.
Patient Testimonies
Users who have come off the jabs explain a intense resurgence of hunger.
"It was like something activating and you're instantly starving," recalled an individual.
The struggle is compounded if users have not adopted permanent lifestyle or habit changes during therapy.
Growing Use
Survey data suggest that millions of adults in the UK have tried weight-loss jabs in the past year, with demand continuing to grow.
- Use is greater among women than men.
- The 40s and 50s demographic shows the greatest usage rates.
- Many obtain the drugs through private healthcare rather than the NHS.
Finally, clinicians emphasize that while the jabs are powerful tools for shedding pounds, they are not a magic solution and maintained weight loss relies on combined behavioural management.
