Fresh analysis suggests that individuals who come off blockbuster GLP-1 drugs like Mounjaro or Wegovy may regain reduced body mass much more quickly than those who halt traditional lifestyle plans.
Findings released in a prominent health publication demonstrates that while overweight people 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 after stopping.
"Individuals using these medications need to be aware of the danger of rapid rebound weight gain when the medication is stopped," warns lead investigator Dr. Susan Jebb.
Such speed of recovery means a reversion to original weight within about one and a half years.
Weighing Therapies
The study, which looked at 37 of trials involving over 9,000 of participants, compared the effects of these new drugs with older methods.
The team emphasize that people who lose weight through lifestyle changes alone generally experience a slower weight regain—approximately 100 grams monthly—once they finish.
Explaining the Quick Rebound
Nutrition scientists propose the way of the drugs is key to understanding the accelerated rebound.
These medications imitate a natural hormone called GLP-1, which moderates feelings of fullness.
"Sustained high doses of the hormone concentrations several times higher than normal may cause the system to produce less of its own natural hormone, and could lessen sensitivity to its actions," said Dr. Adam Collins, a nutrition specialist.
"Stopping of this medication means appetite is unsuppressed, making excessive eating much more probable."
A Lifelong Disease?
Medical guidelines suggest the jabs for individuals with obesity-related medical conditions, accompanied by prescribed lifestyle changes.
A number of clinicians contend that, considering the significant potential of relapse, the therapy might need to be life-long.
This view is supported by pharmaceutical companies, who note that the findings "underscore the persistent character of excess weight," comparing it to managing conditions like high blood pressure.
User Testimonies
Individuals who have stopped the medication report a powerful return of appetite.
"It felt as if a switch that goes on and you're instantly extremely hungry," said an individual.
The struggle is worsened if patients have not adopted permanent lifestyle or habit changes during therapy.
Significant Use
Survey data suggest that a significant number of people in the UK have used weight-loss jabs in the last 12 months, with demand being substantial.
- Adoption is higher among females compared to males.
- The 40s and 50s demographic shows the greatest level of interest.
- A large proportion obtain the medications through private prescriptions rather than the NHS.
Finally, clinicians stress that while the jabs are powerful agents for shedding pounds, they are not a permanent fix and maintained weight loss relies on ongoing lifestyle changes.
