Fresh analysis reveals that individuals who discontinue popular slimming jabs like Wegovy and Mounjaro tend to recover lost weight far faster than those who stop conventional diet and exercise regimens.
Research printed in a prominent medical journal points out that while obese individuals can lose a large proportion of their total mass while undergoing treatment, the mass comes back at an estimated rate of nearly a kilo each month upon discontinuation.
"Users using these drugs should be aware of the risk of rapid rebound weight gain when the medication is stopped," cautioned expert Dr. Susan Jebb.
Such speed of recovery means a return to original weight in about 18 months.
Comparing Therapies
The study, which examined 37 of studies involving thousands of participants, contrasted the results of GLP-1 agonists with conventional dieting.
Scientists note that individuals who lose weight through diet and exercise typically see a slower creep back—approximately 0.1 kg a month—after stopping.
Explaining the Rapid Regain
Nutrition scientists propose the mechanism of the injections is key to understanding the heightened weight return.
These medications copy a body's own chemical called glucagon-like peptide-1, which helps regulate appetite.
"Sustained high doses of GLP-1 levels far above than normal may cause the system to generate a reduced amount of its endogenous GLP-1, and could lessen responsiveness to its actions," explained Dr. Adam Collins, a nutrition specialist.
"Discontinuation of this medication results in appetite is no longer kept in check, making overeating a significant risk."
A Lifelong Disease?
The NHS recommend the injections for individuals with weight-linked medical conditions, alongside prescribed diet and exercise modifications.
A number of clinicians say that, considering the significant potential of weight regain, the therapy should be considered ongoing.
This perspective is reinforced by drug manufacturers, who say that the results "emphasize the long-term character of excess weight," similar to managing conditions like diabetes.
Patient Testimonies
People who have stopped the medication report a intense return of appetite.
"It felt as if a trigger activating and I was suddenly starving," described one woman.
This challenge is worsened if patients have not established sustainable lifestyle or habit modifications during therapy.
Growing Interest
Survey data indicate that a significant number of people in the UK have tried these injections in the past year, with demand remaining high.
- Adoption is greater among females compared to males.
- The 40s and 50s age group shows the greatest level of interest.
- Many access the drugs through private prescriptions rather than public health services.
Ultimately, clinicians caution that while the jabs are effective agents for shedding pounds, they are not a magic fix and lasting health benefits hinges on combined behavioural support.
