A recent study indicates that individuals who discontinue popular slimming jabs like Mounjaro or Wegovy tend to recover reduced body mass much more quickly than those who halt conventional lifestyle programs.
Research printed in a leading medical journal demonstrates that while overweight individuals frequently drop a large proportion of their body weight while on the medication, the weight returns at an average rate of 0.8 kg per month upon discontinuation.
"Individuals purchasing such drugs need to be informed of the potential of rapid rebound weight gain when the medication ends," warns expert Dr. Susan Jebb.
This pace of regain implies a return to starting weight within about a year and a half.
Weighing Treatments
The research, which examined dozens of studies involving thousands of participants, compared the outcomes of these new drugs with other pills.
The team note that people who lose weight through dieting generally experience a slower weight regain—around 0.1 kg a month—once they finish.
Understanding the Rapid Regain
Nutrition scientists suggest the mode of action of the injections accounts for the accelerated regain.
The injections imitate a natural hormone called GLP-1, which controls hunger.
"Artificially providing GLP-1 levels several times higher than normal may cause the system to produce less of its own natural hormone, and could reduce sensitivity to its actions," explained Dr. Adam Collins, a nutrition expert.
"Withdrawal of this hormone supplement means appetite is unsuppressed, making binge eating much more probable."
A Chronic Issue?
The NHS advise the jabs for individuals with obesity-related health risks, accompanied by recommended diet and exercise modifications.
Professionals argue that, due to the likelihood of weight regain, the treatment should be considered long-term.
This view is echoed by drug manufacturers, who say that the findings "underscore the chronic character of excess weight," comparing it to managing conditions like high blood pressure.
User Accounts
Users who have come off the jabs describe a intense resurgence of appetite.
"It was like a trigger activating and you're instantly ravenous," described an individual.
This challenge is compounded if patients have not developed sustainable dietary or behavioural changes during therapy.
Growing Use
Survey data show that millions of adults in the UK have used weight-loss jabs in the past year, with desire remaining high.
- Use is more common among women compared to males.
- The 40s and 50s age group shows the highest level of interest.
- A large proportion access the drugs through private prescriptions rather than the NHS.
Ultimately, experts caution that while these medications are effective agents for shedding pounds, they are not a magic cure and long-term success relies on combined behavioural changes.
