Fresh analysis suggests that individuals who discontinue new slimming jabs like Wegovy and Mounjaro tend to recover shed pounds far faster than those who stop conventional lifestyle regimens.
Published data in a leading health publication demonstrates that while overweight individuals often shed about a fifth of their total mass while using the jabs, the weight is regained at an average rate of 0.8 kg per month once they quit.
"Individuals buying such treatments need to be aware of the danger of rapid weight regain when the medication concludes," stated expert Dr. Susan Jebb.
That rate of regain implies a return to pre-treatment mass in about 18 months.
Analyzing Approaches
The analysis, which reviewed 37 of trials involving over 9,000 of participants, contrasted the effects of the injectable medications with older methods.
The team emphasize that people who shed pounds through lifestyle changes alone generally have a more gradual creep back—approximately 100 grams monthly—after stopping.
Explaining the Fast Regain
Experts suggest the mode of action of the drugs is key to understanding the accelerated rebound.
The injections imitate a body's own chemical called GLP-1, which controls appetite.
"Sustained high doses of the hormone concentrations several times higher than normal might result in the system to produce less of its endogenous hormone, and may also lessen sensitivity to its actions," noted Dr. Adam Collins, a nutrition specialist.
"Stopping of this GLP-1 'fix' results in hunger is no longer kept in check, making binge eating much more probable."
A Chronic Disease?
The NHS suggest the injections for individuals with obesity-related medical conditions, accompanied by prescribed lifestyle changes.
Professionals argue that, given the high risk of relapse, the treatment might need to be long-term.
This opinion is supported by pharmaceutical companies, who say that the results "underscore the chronic nature of excess weight," similar to managing diseases like diabetes.
Patient Experiences
Individuals who have come off the medication describe a powerful resurgence of appetite.
"It was like a trigger that goes on and you're instantly starving," said a patient.
This difficulty is worsened if individuals have not established lasting dietary or behavioural changes during treatment.
Growing Use
Recent estimates show that a significant number of adults in the UK have used these injections in the last 12 months, with demand being substantial.
- Adoption is higher among women compared to males.
- The middle-aged demographic shows the highest level of interest.
- Many access the medications through private healthcare rather than the NHS.
In conclusion, clinicians emphasize that while these medications are powerful tools for weight loss, they are not a permanent cure and maintained weight loss relies on ongoing lifestyle changes.
