New research suggests that people who discontinue popular GLP-1 drugs like Wegovy and Mounjaro can put back on reduced body mass at a significantly accelerated pace than those who halt conventional lifestyle plans.
Published data in a major medical journal demonstrates that while obese individuals often shed a large proportion of their total mass while using the jabs, the weight is regained at an estimated rate of 0.8 kg per month once they quit.
"People using these medications must be cognizant of the danger of rapid rebound weight gain when the treatment ends," stated expert Dr. Susan Jebb.
This pace of regain suggests a return to starting mass within about a year and a half.
Comparing Therapies
The research, which examined 37 of studies involving thousands of patients, contrasted the results of the injectable medications with older methods.
The team emphasize that individuals who lose weight through dieting usually have a slower creep back—perhaps 100 grams monthly—after stopping.
The Reason for the Rapid Rebound
Experts propose the mode of action of the injections explains the accelerated weight return.
The injections mimic a natural hormone called GLP-1, which controls hunger.
"Sustained high doses of GLP-1 concentrations far above than the body's typical production may cause the body to generate a reduced amount of its endogenous hormone, and may also reduce responsiveness to its effects," said Dr. Adam Collins, a nutrition researcher.
"Discontinuation of this GLP-1 'fix' results in hunger is no longer kept in check, making binge eating much more probable."
An Ongoing Disease?
Health authorities advise the jabs for individuals with weight-linked medical conditions, accompanied by recommended diet and exercise modifications.
A number of clinicians contend that, considering the likelihood of relapse, the treatment might need to be long-term.
This view is reinforced by drug manufacturers, who say that the results "underscore the persistent nature of excess weight," similar to managing conditions like high blood pressure.
User Experiences
People who have come off the medication describe a powerful resurgence of cravings.
"I experienced a switch activating and you're instantly extremely hungry," recalled one woman.
The struggle is compounded if individuals have not developed sustainable lifestyle or habit modifications during treatment.
Significant Interest
Survey data show that a significant number of adults in the UK have tried weight-loss jabs in the past year, with interest continuing to grow.
- Use is greater among females than men.
- The middle-aged demographic shows the greatest usage rates.
- Many access the medications through private prescriptions rather than the NHS.
In conclusion, researchers emphasize that while these medications are powerful agents for shedding pounds, they are not a permanent fix and long-term success relies on integrated behavioural changes.
