Fresh analysis reveals that patients who come off popular GLP-1 drugs like Mounjaro or Wegovy can put back on lost weight at a significantly accelerated pace than those who halt traditional diet and exercise plans.
Published data in a leading health publication demonstrates that while obese individuals often shed a large proportion of their body weight while undergoing treatment, the weight comes back at an average rate of 0.8 kg per month once they quit.
"People purchasing these drugs should be cognizant of the risk of quick rebound weight gain when the treatment concludes," cautioned expert Dr. Susan Jebb.
Such speed of regain suggests a return to starting weight within about 18 months.
Analyzing Therapies
The study, which reviewed 37 of trials involving over 9,000 of patients, compared the results of these new drugs with older methods.
The team point out that individuals who lose weight through lifestyle changes alone usually see a more gradual weight regain—around 0.1 kg a month—after stopping.
The Reason for the Fast Regain
Experts propose the way of the jabs accounts for the accelerated weight return.
These medications imitate a body's own chemical called glucagon-like peptide-1, which moderates hunger.
"Artificially providing GLP-1 levels several times higher than the body's typical production might result in the body to produce less of its endogenous hormone, and could diminish sensitivity to its effects," said Dr. Adam Collins, a nutrition expert.
"Stopping of this GLP-1 'fix' leads to appetite is unsuppressed, making excessive eating much more probable."
An Ongoing Disease?
Medical guidelines recommend the jabs for individuals with obesity-related health risks, alongside recommended diet and exercise modifications.
A number of clinicians argue that, considering the likelihood of weight regain, the treatment should be considered long-term.
This view is echoed by drug manufacturers, who note that the findings "emphasize the persistent nature of excess weight," similar to managing conditions like high blood pressure.
User Testimonies
Users who have come off the jabs report a sudden return of hunger.
"It was like a switch activating and I was suddenly starving," recalled a patient.
The struggle is compounded if users have not established lasting lifestyle or habit changes during treatment.
Significant Use
Recent estimates show that millions of people in the UK have tried these injections in the last 12 months, with desire continuing to grow.
- 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 healthcare rather than the NHS.
Ultimately, clinicians emphasize that while the jabs are effective agents for shedding pounds, they are not a magic solution and maintained weight loss relies on combined lifestyle management.
