Fresh analysis reveals that individuals who come off new GLP-1 drugs like Wegovy and Mounjaro can put back on reduced body mass much more quickly than those who halt traditional lifestyle programs.
Published data in a leading medical journal demonstrates that while obese individuals frequently drop substantial amounts of their total mass while undergoing treatment, the mass comes back at an estimated rate of nearly a kilo each month after stopping.
"People using these medications should be aware of the danger of rapid rebound weight gain when the medication ends," cautioned researcher Dr. Susan Jebb.
That rate of regain suggests a return to original mass in about a year and a half.
Analyzing Approaches
The analysis, which reviewed 37 of studies involving over 9,000 of participants, contrasted the outcomes of the injectable medications with older methods.
Researchers note that individuals who shed pounds through diet and exercise usually experience a slower weight regain—approximately 100 grams monthly—once they finish.
Explaining the Fast Regain
Experts believe the mechanism of the injections is key to understanding the accelerated rebound.
The injections mimic a natural hormone called GLP-1, which helps regulate appetite.
"Artificially providing GLP-1 levels far above than the body's typical production could lead to the body to produce less of its own natural hormone, and may also lessen responsiveness to its actions," noted Dr. Adam Collins, a nutrition specialist.
"Withdrawal of this medication results in appetite is uncontrolled, making overeating a significant risk."
A Lifelong Condition?
The NHS recommend the injections for individuals with obesity-related health risks, accompanied by prescribed diet and exercise modifications.
A number of clinicians say that, considering the high risk of weight regain, the therapy might need to be ongoing.
This perspective is echoed by drug manufacturers, who note that the results "highlight the persistent character of obesity," comparing it to managing conditions like diabetes.
Patient Testimonies
Individuals who have come off the jabs report a intense resurgence of cravings.
"I experienced a trigger activating and you're instantly starving," recalled one woman.
This difficulty is exacerbated if users have not developed lasting lifestyle or habit modifications during treatment.
Widespread Use
Survey data show that a significant number of adults in the UK have tried weight-loss jabs in the last 12 months, with interest continuing to grow.
- Use is more common among women compared to males.
- The 40s and 50s demographic shows the highest level of interest.
- A large proportion obtain the drugs through private prescriptions rather than public health services.
Ultimately, clinicians emphasize that while the jabs are powerful tools for weight loss, they are not a magic fix and maintained weight loss likely depends on integrated lifestyle management.
