New research suggests that patients who discontinue blockbuster slimming jabs like Mounjaro or Wegovy tend to recover reduced body mass much more quickly than those who end conventional lifestyle programs.
Findings released in a major health publication shows that while overweight people can lose a large proportion of their body weight while undergoing treatment, the weight is regained at an estimated rate of nearly a kilo each month after stopping.
"Individuals buying these medications need to be aware of the potential of quick rebound weight gain when the therapy ends," warns lead investigator Dr. Susan Jebb.
Such speed of recovery suggests a reversion to original mass in about 18 months.
Analyzing Treatments
The analysis, which looked at dozens of studies involving over 9,000 of participants, contrasted the effects of the injectable medications with conventional dieting.
Scientists emphasize that people who shed pounds through dieting usually have a more gradual weight regain—approximately 100 grams monthly—post-intervention.
Understanding the Rapid Regain
Experts propose the mechanism of the injections accounts for the amplified rebound.
The injections mimic a natural hormone called glucagon-like peptide-1, which helps regulate feelings of fullness.
"Sustained high doses of GLP-1 concentrations several times higher than the body's typical production may cause the body to produce less of its endogenous GLP-1, and may also diminish responsiveness to its effects," said Dr. Adam Collins, a dietetics researcher.
"Stopping of this GLP-1 'fix' means hunger is unsuppressed, making overeating far more likely."
A Chronic Issue?
The NHS suggest the jabs for individuals with weight-linked health risks, accompanied by recommended diet and exercise modifications.
Professionals contend that, considering the high risk of weight regain, the treatment might need to be life-long.
This perspective is reinforced by drug manufacturers, who note that the results "underscore the chronic nature of obesity," similar to managing diseases like diabetes.
User Accounts
People who have stopped the jabs report a intense return of hunger.
"I experienced something activating and you become ravenous," described one woman.
This difficulty is worsened if patients have not developed lasting lifestyle or habit changes during treatment.
Significant Interest
Figures suggest that millions of people in the UK have tried these injections in the last 12 months, with desire continuing to grow.
- Adoption is higher among women than men.
- The 40s and 50s age group shows the greatest level of interest.
- A large proportion obtain the medications through private prescriptions rather than public health services.
Ultimately, experts caution that while these medications are effective agents for weight loss, they are not a standalone cure and lasting health benefits likely depends on ongoing lifestyle changes.
