Fresh analysis suggests that individuals who stop using new slimming jabs like Mounjaro or Wegovy tend to recover lost weight at a significantly accelerated pace than those who halt conventional lifestyle plans.
Published data in a major medical journal points out that while obese people can lose a large proportion of their total mass while using the jabs, the mass comes back at an average rate of 0.8 kg per month after stopping.
"Users buying such drugs should be cognizant of the risk of rapid weight regain when the medication is stopped," stated expert Dr. Susan Jebb.
This pace of regain implies a return to original weight in about 18 months.
Analyzing Treatments
The research, which examined dozens of trials involving over 9,000 of patients, compared the outcomes of GLP-1 agonists with conventional dieting.
Researchers note that individuals who shed pounds through lifestyle changes alone typically experience a less rapid creep back—approximately 0.1 kg a month—once they finish.
Understanding the Quick Rebound
Doctors suggest the mechanism of the drugs accounts for the accelerated rebound.
The injections imitate a body's own chemical called glucagon-like peptide-1, which controls hunger.
"Sustained high doses of GLP-1 levels several times higher than the body's typical production could lead to the system to produce less of its endogenous hormone, and could reduce sensitivity to its actions," said Dr. Adam Collins, a nutrition specialist.
"Discontinuation of this hormone supplement leads to appetite is unsuppressed, making binge eating much more probable."
A Chronic Condition?
The NHS recommend the injections for individuals with weight-linked health risks, accompanied by prescribed diet and exercise modifications.
Many experts say that, given the high risk of weight regain, the therapy is often long-term.
This view is reinforced by drug manufacturers, who state that the results "emphasize the persistent nature of obesity," akin to managing conditions like diabetes.
Patient Accounts
People who have discontinued the medication explain a intense resurgence of hunger.
"It was like something that goes on and you become ravenous," said one woman.
This challenge is worsened if individuals have not adopted permanent lifestyle or habit changes during therapy.
Widespread Interest
Figures show that millions of adults in the UK have used these injections in the last 12 months, with interest remaining high.
- Adoption is greater among females than men.
- The 40s and 50s age group shows the highest level of interest.
- A large proportion obtain the drugs through private healthcare rather than the NHS.
In conclusion, clinicians caution that while these medications are potent tools for weight loss, they are not a permanent fix and maintained weight loss hinges on integrated behavioural changes.
