Fresh analysis suggests that individuals who stop using blockbuster slimming jabs like Wegovy and Mounjaro can put back on reduced body mass at a significantly accelerated pace than those who stop conventional diet and exercise plans.
Published data in a leading medical journal shows that while overweight people can lose a large proportion of their total mass while undergoing treatment, the weight comes back at an average rate of nearly a kilo each month upon discontinuation.
"People buying these treatments should be aware of the risk of fast weight regain when the medication is stopped," stated researcher Dr. Susan Jebb.
This pace of regain means a return to pre-treatment mass in about one and a half years.
Comparing Treatments
The research, which examined dozens of trials involving over 9,000 of patients, compared the results of the injectable medications with older methods.
The team note that people who lose weight through dieting generally see a slower creep back—around 100 grams monthly—once they finish.
The Reason for the Quick Regain
Nutrition scientists propose the mode of action of the jabs explains the accelerated weight return.
These medications mimic a body's own chemical called GLP-1, which helps regulate appetite.
"Long-term administration of GLP-1 concentrations several times higher than normal may cause the body to generate a reduced amount of its endogenous hormone, and could lessen sensitivity to its actions," noted Dr. Adam Collins, a dietetics researcher.
"Stopping of this hormone supplement leads to appetite is unsuppressed, making excessive eating far more likely."
A Chronic Disease?
Medical guidelines advise the jabs for individuals with weight-linked medical conditions, alongside recommended lifestyle changes.
A number of clinicians say that, considering the likelihood of relapse, the therapy is often life-long.
This opinion is supported by pharmaceutical companies, who state that the findings "underscore the chronic nature of obesity," similar to managing conditions like hypertension.
User Testimonies
People who have come off the medication explain a intense return of cravings.
"It was like something flipping and you're instantly starving," described one woman.
The struggle is worsened if patients have not established permanent dietary or behavioural modifications during treatment.
Widespread Interest
Survey data suggest that millions of adults in the UK have used these injections in the past year, with desire being substantial.
- Use is more common among women than men.
- The middle-aged age group shows the highest level of interest.
- A large proportion access the drugs through private prescriptions rather than the NHS.
Ultimately, clinicians caution that while the jabs are effective tools for shedding pounds, they are not a permanent cure and long-term success hinges on integrated lifestyle support.
