A recent study suggests that individuals who stop using blockbuster GLP-1 drugs like Mounjaro or Wegovy tend to recover reduced body mass far faster than those who halt conventional diet and exercise programs.
Research printed in a major medical journal points out that while overweight people frequently drop substantial amounts of their body weight while using the jabs, the weight is regained at an average rate of 0.8 kg per month once they quit.
"Individuals purchasing such treatments should be aware of the potential of rapid rebound weight gain when the therapy ends," warns expert Dr. Susan Jebb.
This pace of recovery means a return to pre-treatment weight in about 18 months.
Weighing Treatments
The analysis, which examined dozens of studies involving over 9,000 of patients, compared the effects of GLP-1 agonists with conventional dieting.
Researchers emphasize that individuals who lose weight through dieting usually experience a more gradual weight regain—approximately 100 grams monthly—post-intervention.
The Reason for the Fast Rebound
Doctors suggest the way of the injections explains the heightened regain.
GLP-1 drugs imitate a natural hormone called glucagon-like peptide-1, which moderates feelings of fullness.
"Sustained high doses of the hormone levels far above than the body's typical production could lead to the body to generate a reduced amount of its endogenous GLP-1, and may also reduce responsiveness to its actions," noted Dr. Adam Collins, a dietetics specialist.
"Withdrawal of this medication results in appetite is uncontrolled, making overeating much more probable."
A Chronic Disease?
Medical guidelines recommend the injections for individuals with obesity-related medical conditions, accompanied by recommended diet and exercise modifications.
A number of clinicians contend that, considering the high risk of weight regain, the therapy should be considered long-term.
This perspective is echoed by pharmaceutical companies, who say that the findings "underscore the chronic nature of obesity," akin to managing diseases like diabetes.
User Testimonies
People who have stopped the jabs explain a intense resurgence of hunger.
"It was like a trigger that goes on and you become starving," described one woman.
This difficulty is compounded if patients have not established permanent lifestyle or habit changes during therapy.
Growing Use
Figures suggest that millions of adults in the UK have tried these injections in the last 12 months, with demand being substantial.
- Use is greater among females than men.
- The 40s and 50s age group shows the greatest usage rates.
- Many obtain the medications through private prescriptions rather than the NHS.
Ultimately, experts stress that while the jabs are effective tools for shedding pounds, they are not a standalone cure and long-term success hinges on integrated lifestyle support.
