Fresh analysis indicates that individuals who stop using popular GLP-1 drugs like Mounjaro or Wegovy can put back on reduced body mass much more quickly than those who stop conventional diet and exercise regimens.
Published data in a prominent health publication points out that while overweight individuals frequently drop a large proportion of their body weight while undergoing treatment, the mass returns at an average rate of 0.8 kg per month after stopping.
"People buying such drugs should be informed of the danger of fast rebound weight gain when the medication concludes," cautioned expert Dr. Susan Jebb.
Such speed of recovery suggests a reversion to original mass within about a year and a half.
Analyzing Treatments
The research, which reviewed dozens of trials involving over 9,000 of participants, contrasted the outcomes of GLP-1 agonists with conventional dieting.
Researchers note that individuals who shed pounds through diet and exercise typically have a more gradual weight regain—perhaps 0.1 kg a month—once they finish.
The Reason for the Fast Rebound
Nutrition scientists suggest the mechanism of the jabs explains the heightened rebound.
The injections mimic a natural hormone called GLP-1, which helps regulate appetite.
"Artificially providing the hormone levels several times higher than the body's typical production might result in the system to produce less of its endogenous hormone, and could reduce responsiveness to its effects," noted Dr. Adam Collins, a dietetics expert.
"Discontinuation of this hormone supplement results in appetite is no longer kept in check, making excessive eating much more probable."
An Ongoing Disease?
Medical guidelines recommend the injections for individuals with obesity-related medical conditions, accompanied by recommended diet and exercise modifications.
A number of clinicians say that, considering the likelihood of relapse, the treatment might need to be long-term.
This view is supported by pharmaceutical companies, who state that the findings "emphasize the long-term nature of obesity," comparing it to managing diseases like diabetes.
User Testimonies
People who have come off the medication report a intense return of hunger.
"I experienced a switch that goes on and you become ravenous," said one woman.
The struggle is exacerbated if individuals have not adopted sustainable dietary or behavioural changes during therapy.
Widespread Adoption
Recent estimates indicate that millions of adults in the UK have tried these injections in the past year, with desire being substantial.
- Use is greater among women than males.
- The 40s and 50s age group shows the greatest level of interest.
- Many obtain the drugs through private prescriptions rather than the NHS.
Ultimately, clinicians stress that while GLP-1 drugs are powerful tools for weight loss, they are not a standalone fix and lasting health benefits hinges on combined behavioural changes.
