Fresh analysis indicates that patients who come off blockbuster slimming jabs like Mounjaro or Wegovy tend to recover reduced body mass far faster than those who stop conventional diet and exercise plans.
Published data in a prominent medical journal points out that while obese individuals can lose substantial amounts of their total mass while using the jabs, the weight comes back at an average rate of 0.8 kg per month upon discontinuation.
"Users purchasing such medications need to be informed of the risk of rapid weight regain when the treatment ends," warns expert Dr. Susan Jebb.
That rate of recovery means a return to pre-treatment mass in about one and a half years.
Comparing Approaches
The analysis, which looked at dozens of trials involving thousands of participants, compared the outcomes of GLP-1 agonists with conventional dieting.
Researchers note that individuals who lose weight through lifestyle changes alone typically experience a more gradual creep back—around 0.1 kg a month—after stopping.
Explaining the Rapid Regain
Doctors believe the way of the injections is key to understanding the amplified rebound.
The injections mimic a natural hormone called GLP-1, which moderates appetite.
"Sustained high doses of the hormone levels several times higher than normal could lead to the body to produce less of its endogenous hormone, and may also lessen sensitivity to its actions," explained Dr. Adam Collins, a dietetics researcher.
"Discontinuation of this hormone supplement means appetite is no longer kept in check, making binge eating much more probable."
A Lifelong Condition?
The NHS recommend 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 should be considered long-term.
This perspective is echoed by drug manufacturers, who state that the findings "highlight the persistent nature of excess weight," similar to managing diseases like hypertension.
User Experiences
Individuals who have discontinued the jabs report a powerful resurgence of appetite.
"It was like a switch activating and you're instantly extremely hungry," said an individual.
The struggle is exacerbated if individuals have not developed sustainable lifestyle or habit modifications during treatment.
Widespread Adoption
Recent estimates indicate that millions of people in the UK have used these injections in the past year, with demand remaining high.
- Use is greater among females compared to males.
- The 40s and 50s demographic shows the highest usage rates.
- A large proportion access the medications through private prescriptions rather than public health services.
Ultimately, clinicians stress that while the jabs are effective tools for shedding pounds, they are not a permanent fix and lasting health benefits likely depends on ongoing lifestyle changes.
