Fresh analysis indicates that individuals who stop using popular slimming jabs like Wegovy and Mounjaro may regain reduced body mass much more quickly than those who end traditional diet and exercise programs.
Research printed in a major medical journal demonstrates that while overweight individuals can lose substantial amounts of their body weight while using the jabs, the mass comes back at an estimated rate of 0.8 kg per month upon discontinuation.
"People purchasing these medications need to be cognizant of the risk of rapid rebound weight gain when the therapy is stopped," warns researcher Dr. Susan Jebb.
This pace of regain implies a return to pre-treatment mass within about a year and a half.
Analyzing Therapies
The research, which looked at dozens of studies involving thousands of participants, contrasted the outcomes of GLP-1 agonists with conventional dieting.
Researchers emphasize that people who shed pounds through lifestyle changes alone typically experience a more gradual creep back—around 0.1 kg a month—after stopping.
The Reason for the Fast Regain
Experts suggest the mechanism of the drugs is key to understanding the heightened regain.
The injections imitate a body's own chemical called GLP-1, which moderates feelings of fullness.
"Sustained high doses of the hormone concentrations far above than the body's typical production may cause the body to generate a reduced amount of its endogenous hormone, and could lessen sensitivity to its actions," explained Dr. Adam Collins, a nutrition expert.
"Discontinuation of this medication means hunger is unsuppressed, making excessive eating far more likely."
An Ongoing Disease?
The NHS recommend the jabs for people with obesity-related medical conditions, accompanied by recommended diet and exercise modifications.
Many experts contend that, due to the high risk of weight regain, the treatment should be considered ongoing.
This view is supported by drug manufacturers, who note that the results "highlight the persistent character of obesity," comparing it to managing conditions like high blood pressure.
User Testimonies
People who have come off the medication describe a intense resurgence of hunger.
"I experienced a switch that goes on and you become starving," recalled one woman.
This challenge is exacerbated if individuals have not developed lasting dietary or behavioural changes during treatment.
Significant Adoption
Figures suggest that millions of adults in the UK have tried these injections in the last 12 months, with desire remaining high.
- Adoption is more common among females compared to males.
- The 40s and 50s age group shows the highest usage rates.
- A large proportion obtain the medications through private prescriptions rather than public health services.
Finally, researchers emphasize that while these medications are powerful tools for shedding pounds, they are not a magic fix and long-term success hinges on ongoing behavioural management.
