New research reveals that patients who discontinue blockbuster GLP-1 drugs like Wegovy and Mounjaro may regain shed pounds at a significantly accelerated pace than those who stop conventional lifestyle programs.
Research printed in a prominent medical journal points out that while overweight individuals can lose substantial amounts of their total mass while on the medication, the mass is regained at an average rate of nearly a kilo each month once they quit.
"Users purchasing such drugs must be aware of the potential of rapid rebound weight gain when the therapy concludes," stated expert Dr. Susan Jebb.
This pace of regain suggests a return to original mass within about one and a half years.
Analyzing Approaches
The research, which looked at dozens of studies involving thousands of participants, compared the results of the injectable medications with conventional dieting.
The team point out that individuals who lose weight through dieting generally see a more gradual creep back—approximately 0.1 kg a month—after stopping.
The Reason for the Fast Regain
Experts suggest the mode of action of the injections is key to understanding the heightened weight return.
These medications copy a natural hormone called GLP-1, which helps regulate appetite.
"Sustained high doses of GLP-1 concentrations several times higher than normal may cause the system to produce less of its own natural GLP-1, and could diminish responsiveness to its actions," noted Dr. Adam Collins, a dietetics researcher.
"Withdrawal of this GLP-1 'fix' leads to hunger is uncontrolled, making binge eating far more likely."
A Lifelong Disease?
The NHS advise the jabs for individuals with weight-linked medical conditions, accompanied by prescribed diet and exercise modifications.
A number of clinicians say that, considering the high risk of weight regain, the therapy should be considered ongoing.
This view is supported by pharmaceutical companies, who note that the findings "underscore the chronic character of excess weight," comparing it to managing diseases like diabetes.
Patient Experiences
Individuals who have stopped the jabs report a sudden resurgence of cravings.
"It was like a trigger activating and I was suddenly starving," recalled an individual.
The struggle is worsened if users have not adopted permanent lifestyle or habit modifications during therapy.
Growing Interest
Figures indicate that millions of adults in the UK have tried these injections in the last 12 months, with interest being substantial.
- Adoption is more common among women than males.
- The 40s and 50s demographic shows the highest level of interest.
- Many obtain the drugs through private healthcare rather than public health services.
Finally, experts stress that while the jabs are effective agents for weight loss, they are not a permanent solution and long-term success relies on integrated behavioural support.
