New research indicates that people who stop using blockbuster weight-loss injections like Mounjaro or Wegovy may regain reduced body mass much more quickly than those who end traditional lifestyle programs.
Research printed in a major health publication shows that while overweight people often shed substantial amounts of their total mass while undergoing treatment, the weight comes back at an average rate of nearly a kilo each month once they quit.
"Users buying these drugs should be cognizant of the risk of fast weight regain when the medication concludes," warns lead investigator Dr. Susan Jebb.
That rate of recovery implies a reversion to pre-treatment weight in about 18 months.
Analyzing Approaches
The study, which looked at 37 of trials involving over 9,000 of patients, compared the outcomes of these new drugs with older methods.
Scientists note that people who lose weight through dieting generally see a slower creep back—perhaps 100 grams monthly—post-intervention.
Explaining the Quick Regain
Experts propose the mode of action of the injections is key to understanding the accelerated rebound.
GLP-1 drugs mimic a natural hormone called glucagon-like peptide-1, which controls appetite.
"Artificially providing the hormone levels far above than the body's typical production might result in the body to produce less of its endogenous hormone, and could reduce responsiveness to its effects," noted Dr. Adam Collins, a nutrition specialist.
"Stopping of this hormone supplement means hunger is no longer kept in check, making binge eating much more probable."
A Chronic Disease?
The NHS advise the jabs for people with weight-linked medical conditions, accompanied by prescribed diet and exercise modifications.
Professionals say that, considering the high risk of relapse, the therapy should be considered long-term.
This view is echoed by drug manufacturers, who say that the findings "underscore the long-term character of excess weight," similar to managing conditions like diabetes.
Patient Testimonies
Users who have come off the medication report a intense resurgence of appetite.
"I experienced a switch that goes on and I was suddenly extremely hungry," said one woman.
The struggle is compounded if users have not adopted sustainable dietary or behavioural changes during therapy.
Growing Interest
Survey data indicate that millions of adults in the UK have tried weight-loss jabs in the past year, with interest being substantial.
- Adoption is more common among females than men.
- The 40s and 50s age group shows the highest usage rates.
- A large proportion access the drugs through private prescriptions rather than public health services.
Finally, clinicians stress that while the jabs are potent agents for weight loss, they are not a magic fix and maintained weight loss relies on integrated lifestyle changes.
