A recent study suggests that patients who come off blockbuster slimming jabs like Wegovy and Mounjaro can put back on shed pounds much more quickly than those who halt traditional diet and exercise regimens.
Published data in a prominent health publication shows that while obese individuals frequently drop substantial amounts of their body weight while undergoing treatment, the mass returns at an average rate of nearly a kilo each month upon discontinuation.
"People buying these medications must be cognizant of the danger of rapid weight regain when the medication concludes," warns lead investigator Dr. Susan Jebb.
This pace of recovery means a reversion to pre-treatment mass within about 18 months.
Weighing Therapies
The analysis, which looked at 37 of studies involving thousands of participants, compared the effects of the injectable medications with older methods.
The team point out that people who shed pounds through lifestyle changes alone typically have a more gradual creep back—around 100 grams monthly—post-intervention.
Explaining the Quick Rebound
Nutrition scientists propose the way of the drugs is key to understanding the accelerated weight return.
The injections mimic a natural hormone called glucagon-like peptide-1, which controls appetite.
"Long-term administration of GLP-1 concentrations several times higher than the body's typical production might result in the body to produce less of its endogenous GLP-1, and may also reduce sensitivity to its actions," noted Dr. Adam Collins, a dietetics expert.
"Withdrawal of this GLP-1 'fix' results in hunger is uncontrolled, making overeating a significant risk."
An Ongoing Issue?
Health authorities suggest the injections for individuals with weight-linked health risks, accompanied by prescribed diet and exercise modifications.
A number of clinicians contend that, considering the high risk of relapse, the therapy should be considered life-long.
This view is reinforced by pharmaceutical companies, who note that the findings "highlight the chronic character of excess weight," akin to managing conditions like diabetes.
User Testimonies
Users who have discontinued the medication describe a intense resurgence of hunger.
"It was like a trigger activating and you're instantly starving," described a patient.
This difficulty is exacerbated if individuals have not established permanent dietary or behavioural changes during therapy.
Growing Use
Figures indicate that millions of people in the UK have used weight-loss jabs in the past year, with demand remaining high.
- Adoption is higher among females than men.
- The 40s and 50s age group shows the highest usage rates.
- Many access the medications through private healthcare rather than public health services.
In conclusion, experts stress that while these medications are effective tools for shedding pounds, they are not a standalone cure and long-term success hinges on combined behavioural support.
