A recent study reveals that individuals who come off new slimming jabs like Wegovy and Mounjaro can put back on lost weight at a significantly accelerated pace than those who end conventional diet and exercise regimens.
Findings released in a prominent health publication shows that while obese individuals often shed a large proportion of their body weight while undergoing treatment, the mass is regained at an average rate of 0.8 kg per month upon discontinuation.
"Individuals buying these medications need to be cognizant of the danger of rapid rebound weight gain when the treatment ends," warns lead investigator Dr. Susan Jebb.
This pace of recovery implies a reversion to original weight in about one and a half years.
Weighing Approaches
The analysis, which looked at 37 of trials involving thousands of patients, contrasted the outcomes of GLP-1 agonists with conventional dieting.
Scientists note that individuals who lose weight through lifestyle changes alone typically have a slower creep back—perhaps 0.1 kg a month—after stopping.
Explaining the Fast Regain
Doctors suggest the mode of action of the injections is key to understanding the accelerated regain.
GLP-1 drugs copy a body's own chemical called GLP-1, which moderates appetite.
"Long-term administration of GLP-1 concentrations several times higher than the body's typical production may cause the system to produce less of its endogenous GLP-1, and could diminish sensitivity to its actions," noted Dr. Adam Collins, a dietetics researcher.
"Discontinuation of this hormone supplement means hunger is no longer kept in check, making excessive eating a significant risk."
An Ongoing Condition?
Health authorities advise the injections for individuals with weight-linked medical conditions, alongside recommended lifestyle changes.
Many experts argue that, due to the likelihood of weight regain, the therapy might need to be ongoing.
This view is supported by pharmaceutical companies, who state that the findings "underscore the chronic nature of obesity," similar to managing diseases like diabetes.
Patient Experiences
Users who have come off the jabs describe a intense return of hunger.
"It was like a trigger activating and I was suddenly ravenous," recalled one woman.
The struggle is worsened if patients have not established sustainable lifestyle or habit changes during therapy.
Widespread Use
Figures suggest that a significant number of people in the UK have used weight-loss jabs in the past year, with demand being substantial.
- Adoption is more common among females than men.
- The 40s and 50s demographic shows the highest usage rates.
- A large proportion obtain the drugs through private healthcare rather than public health services.
Finally, clinicians caution that while the jabs are powerful agents for shedding pounds, they are not a standalone cure and maintained weight loss likely depends on combined lifestyle support.
