A recent study suggests that individuals who come off blockbuster weight-loss injections like Wegovy and Mounjaro may regain reduced body mass much more quickly than those who halt traditional lifestyle regimens.
Published data in a major medical journal demonstrates that while overweight individuals often shed about a fifth of their body weight while undergoing treatment, the weight returns at an estimated rate of 0.8 kg per month after stopping.
"Users buying such drugs should be informed of the risk of rapid rebound weight gain when the medication concludes," stated expert Dr. Susan Jebb.
This pace of recovery suggests a reversion to original weight in about 18 months.
Analyzing Approaches
The analysis, which reviewed dozens of trials involving thousands of participants, compared the outcomes of these new drugs with other pills.
The team point out that individuals who shed pounds through dieting usually experience a more gradual weight regain—approximately 100 grams monthly—after stopping.
Explaining the Fast Rebound
Doctors believe the way of the jabs is key to understanding the accelerated rebound.
GLP-1 drugs mimic a natural hormone called glucagon-like peptide-1, which moderates appetite.
"Sustained high doses of GLP-1 levels far above than the body's typical production may cause the body to produce less of its endogenous hormone, and may also diminish responsiveness to its actions," explained Dr. Adam Collins, a nutrition specialist.
"Withdrawal of this GLP-1 'fix' leads to hunger is unsuppressed, making excessive eating a significant risk."
A Lifelong Condition?
Health authorities recommend the injections for people with obesity-related health risks, accompanied by prescribed lifestyle changes.
Professionals say that, due to the high risk of weight regain, the therapy is often ongoing.
This perspective is reinforced by drug manufacturers, who say that the results "emphasize the long-term character of obesity," comparing it to managing diseases like diabetes.
User Accounts
Users who have discontinued the jabs explain a powerful return of appetite.
"It was like a trigger activating and you're instantly ravenous," described a patient.
The struggle is worsened if users have not developed lasting lifestyle or habit changes during therapy.
Widespread Interest
Survey data suggest that millions of adults in the UK have used weight-loss jabs in the last 12 months, with interest remaining high.
- Use is more common among women compared to males.
- The middle-aged age group shows the greatest usage rates.
- A large proportion obtain the medications through private healthcare rather than the NHS.
Ultimately, clinicians stress that while these medications are powerful tools for shedding pounds, they are not a standalone cure and maintained weight loss hinges on integrated behavioural management.
