Fresh analysis reveals that people who discontinue popular slimming jabs like Wegovy and Mounjaro can put back on shed pounds at a significantly accelerated pace than those who end conventional lifestyle plans.
Research printed in a leading health publication demonstrates that while overweight people frequently drop about a fifth of their body weight while using the jabs, the mass is regained at an average rate of nearly a kilo each month upon discontinuation.
"People buying such medications must be informed of the danger of fast rebound weight gain when the treatment ends," stated researcher Dr. Susan Jebb.
Such speed of regain means a return to pre-treatment mass within about one and a half years.
Comparing Approaches
The research, which looked at 37 of studies involving thousands of patients, compared the effects of the injectable medications with conventional dieting.
Scientists note that people who shed pounds through lifestyle changes alone typically see a slower weight regain—around 100 grams monthly—once they finish.
Understanding the Rapid Regain
Nutrition scientists suggest the mechanism of the jabs explains the amplified regain.
These medications imitate a body's own chemical called glucagon-like peptide-1, which moderates feelings of fullness.
"Long-term administration of GLP-1 levels far above than normal might result in the body to generate a reduced amount of its own natural hormone, and could diminish sensitivity to its actions," noted Dr. Adam Collins, a nutrition expert.
"Discontinuation of this hormone supplement means appetite is unsuppressed, making excessive eating far more likely."
A Chronic Condition?
Health authorities suggest the injections for individuals with obesity-related medical conditions, alongside recommended diet and exercise modifications.
Professionals contend that, due to the likelihood of weight regain, the therapy is often ongoing.
This view is supported by pharmaceutical companies, who note that the results "highlight the chronic character of obesity," comparing it to managing conditions like hypertension.
Patient Testimonies
Users who have stopped the jabs explain a intense return of appetite.
"It was like a switch flipping and you become starving," recalled an individual.
The struggle is exacerbated if users have not developed sustainable lifestyle or habit changes during therapy.
Significant Interest
Survey data show that a significant number of adults in the UK have used weight-loss jabs in the past year, with interest remaining high.
- Use is higher among women than men.
- The 40s and 50s age group shows the greatest usage rates.
- A large proportion obtain the drugs through private healthcare rather than the NHS.
Ultimately, clinicians stress that while these medications are potent agents for shedding pounds, they are not a permanent fix and lasting health benefits likely depends on ongoing behavioural support.
