New research reveals that patients who stop using popular weight-loss injections like Mounjaro or Wegovy can put back on reduced body mass much more quickly than those who end conventional diet and exercise regimens.
Findings released in a leading health publication shows that while obese individuals often shed substantial amounts of their total mass while using the jabs, the mass comes back at an average rate of nearly a kilo each month once they quit.
"People purchasing these treatments must be aware of the risk of rapid weight regain when the medication concludes," warns expert Dr. Susan Jebb.
That rate of regain suggests a return to pre-treatment weight within about one and a half years.
Analyzing Therapies
The study, which reviewed 37 of studies involving thousands of participants, compared the effects of the injectable medications with conventional dieting.
Researchers point out that individuals who shed pounds through lifestyle changes alone typically have a slower creep back—around 0.1 kg a month—after stopping.
Understanding the Rapid Regain
Doctors believe the mode of action of the drugs is key to understanding the heightened rebound.
The injections imitate a natural hormone called GLP-1, which helps regulate feelings of fullness.
"Artificially providing GLP-1 concentrations several times higher than normal could lead to the system to produce less of its endogenous GLP-1, and could lessen sensitivity to its effects," said Dr. Adam Collins, a dietetics specialist.
"Discontinuation of this medication results in hunger is unsuppressed, making excessive eating much more probable."
A Chronic Issue?
Health authorities advise the jabs for individuals with obesity-related medical conditions, alongside prescribed diet and exercise modifications.
Professionals argue that, due to the high risk of weight regain, the therapy should be considered ongoing.
This perspective is echoed by drug manufacturers, who state that the findings "underscore the chronic nature of excess weight," similar to managing conditions like high blood pressure.
User Testimonies
People who have discontinued the jabs describe a intense return of appetite.
"I experienced something activating and you're instantly ravenous," recalled a patient.
The struggle is worsened if individuals have not adopted sustainable dietary or behavioural changes during therapy.
Growing Adoption
Recent estimates show that a significant number of adults in the UK have tried these injections in the last 12 months, with demand remaining high.
- Adoption is more common among females compared to men.
- The 40s and 50s demographic shows the highest usage rates.
- Many obtain the drugs through private prescriptions rather than public health services.
Ultimately, clinicians stress that while the jabs are effective agents for weight loss, they are not a magic solution and maintained weight loss hinges on combined lifestyle changes.
