A recent study suggests that people who discontinue blockbuster GLP-1 drugs like Wegovy and Mounjaro can put back on lost weight at a significantly accelerated pace than those who end conventional diet and exercise programs.
Research printed in a leading health publication points out that while overweight people frequently drop about a fifth of their body weight while using the jabs, the weight comes back at an average rate of nearly a kilo each month after stopping.
"People buying such drugs need to be cognizant of the potential of quick rebound weight gain when the therapy ends," warns lead investigator Dr. Susan Jebb.
This pace of recovery implies a return to starting mass in about 18 months.
Comparing Approaches
The analysis, which looked at dozens of trials involving thousands of patients, contrasted the results of the injectable medications with conventional dieting.
Scientists emphasize that individuals who lose weight through dieting generally experience a more gradual weight regain—approximately 100 grams monthly—once they finish.
Explaining the Rapid Regain
Nutrition scientists propose the mechanism of the drugs explains the accelerated weight return.
GLP-1 drugs copy a natural hormone called glucagon-like peptide-1, which helps regulate appetite.
"Sustained high doses of the hormone levels far above than normal may cause the system to generate a reduced amount of its endogenous GLP-1, and may also diminish responsiveness to its actions," explained Dr. Adam Collins, a nutrition researcher.
"Discontinuation of this GLP-1 'fix' means appetite is no longer kept in check, making excessive eating far more likely."
A Lifelong Issue?
Medical guidelines suggest the jabs for people with weight-linked medical conditions, accompanied by prescribed diet and exercise modifications.
A number of clinicians say that, given the likelihood of relapse, the treatment should be considered life-long.
This view is reinforced by pharmaceutical companies, who say that the findings "highlight the long-term character of excess weight," similar to managing diseases like diabetes.
User Testimonies
People who have come off the medication explain a intense return of cravings.
"I experienced something flipping and I was suddenly starving," said an individual.
The struggle is worsened if users have not established lasting dietary or behavioural modifications during treatment.
Growing Use
Recent estimates suggest that millions of people in the UK have tried weight-loss jabs in the past year, with desire being substantial.
- Adoption is higher among women than males.
- The middle-aged age group shows the greatest usage rates.
- Many obtain the drugs through private prescriptions rather than the NHS.
Ultimately, clinicians stress that while the jabs are potent agents for weight loss, they are not a magic fix and long-term success likely depends on integrated behavioural management.
