A recent study reveals that individuals who discontinue new slimming jabs like Mounjaro or Wegovy can put back on lost weight much more quickly than those who halt conventional diet and exercise programs.
Published data in a major medical journal demonstrates that while obese individuals frequently drop about a fifth of their body weight while using the jabs, the weight comes back at an average rate of 0.8 kg per month once they quit.
"People buying such treatments must be cognizant of the potential of quick rebound weight gain when the medication is stopped," stated researcher Dr. Susan Jebb.
This pace of regain suggests a reversion to pre-treatment weight within about a year and a half.
Comparing Treatments
The research, which looked at 37 of studies involving over 9,000 of participants, contrasted the effects of GLP-1 agonists with conventional dieting.
Researchers note that individuals who shed pounds through dieting typically have a slower weight regain—around 100 grams monthly—post-intervention.
Understanding the Quick Regain
Doctors propose the mode of action of the drugs is key to understanding the heightened weight return.
GLP-1 drugs mimic a natural hormone called GLP-1, which helps regulate appetite.
"Long-term administration of GLP-1 concentrations several times higher than normal could lead to the body to generate a reduced amount of its endogenous GLP-1, and may also reduce sensitivity to its effects," explained Dr. Adam Collins, a nutrition researcher.
"Withdrawal of this hormone supplement results in appetite is no longer kept in check, making overeating much more probable."
A Lifelong Issue?
The NHS advise the injections for individuals with obesity-related medical conditions, alongside prescribed lifestyle changes.
Professionals contend that, due to the high risk of relapse, the therapy might need to be life-long.
This perspective is echoed by pharmaceutical companies, who state that the findings "highlight the chronic nature of obesity," akin to managing conditions like hypertension.
Patient Experiences
Individuals who have come off the medication explain a powerful return of appetite.
"I experienced something flipping and you're instantly starving," recalled an individual.
The struggle is compounded if users have not established lasting dietary or behavioural modifications during treatment.
Widespread Adoption
Survey data indicate that a significant number of people in the UK have used these injections in the past year, with demand remaining high.
- Use is higher among women than males.
- The 40s and 50s age group shows the highest level of interest.
- A large proportion obtain the drugs through private healthcare rather than the NHS.
In conclusion, clinicians caution that while the jabs are powerful tools for shedding pounds, they are not a magic cure and long-term success hinges on ongoing behavioural management.
