Fresh analysis indicates that people who stop using new GLP-1 drugs like Mounjaro or Wegovy can put back on shed pounds at a significantly accelerated pace than those who end conventional diet and exercise programs.
Published data in a prominent health publication points out that while overweight 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 after stopping.
"People purchasing such treatments must be aware of the potential of quick rebound weight gain when the treatment ends," stated researcher Dr. Susan Jebb.
That rate of regain suggests a reversion to pre-treatment mass within about a year and a half.
Analyzing Therapies
The research, which reviewed dozens of studies involving thousands of patients, compared the effects of GLP-1 agonists with older methods.
Scientists point out that individuals who lose weight through dieting typically have a more gradual weight regain—around 0.1 kg a month—post-intervention.
Explaining the Rapid Rebound
Nutrition scientists believe the mechanism of the injections accounts for the heightened regain.
These medications copy a body's own chemical called GLP-1, which controls feelings of fullness.
"Long-term administration of the hormone concentrations several times higher than the body's typical production might result in the body to produce less of its endogenous GLP-1, and may also diminish sensitivity to its effects," noted Dr. Adam Collins, a dietetics specialist.
"Discontinuation of this hormone supplement results in appetite is no longer kept in check, making excessive eating much more probable."
A Lifelong Condition?
Health authorities suggest the injections for people with obesity-related health risks, accompanied by prescribed lifestyle changes.
Professionals say that, considering the likelihood of weight regain, the therapy might need to be long-term.
This perspective is echoed by pharmaceutical companies, who state that the findings "emphasize the long-term character of excess weight," comparing it to managing diseases like high blood pressure.
User Experiences
Users who have come off the medication report a intense resurgence of appetite.
"It was like a trigger that goes on and you're instantly starving," recalled one woman.
The struggle is worsened if users have not established sustainable lifestyle or habit modifications during therapy.
Significant Use
Figures suggest that millions of people in the UK have used weight-loss jabs in the past year, with demand remaining high.
- Adoption is greater among females than males.
- The 40s and 50s age group shows the greatest usage rates.
- Many obtain the medications through private healthcare rather than public health services.
Finally, clinicians caution that while these medications are potent agents for weight loss, they are not a standalone solution and maintained weight loss hinges on combined behavioural changes.
