Fresh analysis indicates that individuals who come off new GLP-1 drugs like Mounjaro or Wegovy may regain shed pounds at a significantly accelerated pace than those who stop conventional diet and exercise programs.
Published data in a major health publication demonstrates that while overweight individuals often shed about a fifth of their body weight while using the jabs, the mass is regained at an estimated rate of nearly a kilo each month once they quit.
"Users buying such drugs need to be aware of the danger of rapid rebound weight gain when the therapy ends," cautioned expert Dr. Susan Jebb.
Such speed of regain suggests a return to pre-treatment weight in about a year and a half.
Analyzing Therapies
The study, which reviewed 37 of studies involving over 9,000 of patients, contrasted the results of GLP-1 agonists with other pills.
Scientists point out that people who shed pounds through diet and exercise usually have a less rapid creep back—approximately 0.1 kg a month—once they finish.
Explaining the Quick Rebound
Nutrition scientists suggest the way of the jabs explains the accelerated rebound.
GLP-1 drugs mimic a natural hormone called GLP-1, which helps regulate feelings of fullness.
"Long-term administration of GLP-1 levels far above than normal might result in the system to produce less of its own natural GLP-1, and may also lessen sensitivity to its actions," said Dr. Adam Collins, a dietetics expert.
"Withdrawal of this medication results in appetite is uncontrolled, making overeating far more likely."
A Lifelong Disease?
Medical guidelines advise the jabs for people with weight-linked health risks, alongside prescribed lifestyle changes.
Professionals contend that, considering the high risk of relapse, the treatment might need to be life-long.
This perspective is echoed by pharmaceutical companies, who note that the results "highlight the persistent nature of obesity," comparing it to managing conditions like high blood pressure.
Patient Testimonies
Individuals who have come off the medication explain a intense return of appetite.
"It was like something activating and you're instantly starving," described an individual.
This challenge is worsened if patients have not adopted permanent dietary or behavioural modifications during treatment.
Growing Adoption
Survey data suggest that millions of adults in the UK have used these injections in the last 12 months, with interest continuing to grow.
- Use is higher among women compared to males.
- The 40s and 50s demographic shows the highest level of interest.
- Many obtain the drugs through private prescriptions rather than public health services.
Finally, experts stress that while GLP-1 drugs are powerful tools for shedding pounds, they are not a magic fix and long-term success hinges on ongoing behavioural support.
