New research reveals that people who discontinue blockbuster slimming jabs like Mounjaro or Wegovy can put back on shed pounds far faster than those who end traditional diet and exercise plans.
Published data in a major medical journal demonstrates that while obese individuals can lose substantial amounts of their total mass while using the jabs, the mass returns at an average rate of 0.8 kg per month after stopping.
"Individuals buying these medications should be informed of the danger of rapid rebound weight gain when the treatment concludes," stated expert Dr. Susan Jebb.
This pace of recovery implies a reversion to original mass within about one and a half years.
Comparing Therapies
The research, which looked at dozens of trials involving over 9,000 of participants, compared the outcomes of the injectable medications with conventional dieting.
Researchers note that individuals who lose weight through diet and exercise typically see a less rapid weight regain—perhaps 100 grams monthly—post-intervention.
Explaining the Rapid Rebound
Nutrition scientists believe the way of the jabs explains the accelerated weight return.
The injections mimic a body's own chemical called GLP-1, which moderates hunger.
"Sustained high doses of the hormone concentrations far above than normal could lead to the body to produce less of its own natural hormone, and may also reduce sensitivity to its effects," noted Dr. Adam Collins, a dietetics researcher.
"Discontinuation of this hormone supplement results in hunger is unsuppressed, making overeating far more likely."
A Lifelong Issue?
The NHS suggest the injections for individuals with weight-linked medical conditions, accompanied by prescribed lifestyle changes.
Professionals argue that, due to the likelihood of weight regain, the treatment should be considered long-term.
This view is reinforced by drug manufacturers, who state that the results "highlight the chronic character of excess weight," akin to managing conditions like diabetes.
Patient Experiences
Users who have stopped the medication describe a intense resurgence of cravings.
"It felt as if a switch flipping and you become starving," said a patient.
The struggle is exacerbated if individuals have not developed sustainable dietary or behavioural changes during therapy.
Widespread Interest
Survey data indicate that millions of people in the UK have tried these injections in the past year, with desire continuing to grow.
- Adoption is higher among females compared to males.
- The 40s and 50s age group shows the greatest usage rates.
- A large proportion obtain the medications through private prescriptions rather than public health services.
Ultimately, clinicians caution that while the jabs are effective tools for shedding pounds, they are not a standalone cure and long-term success likely depends on ongoing behavioural support.
