A recent study indicates that patients who discontinue popular GLP-1 drugs like Mounjaro or Wegovy can put back on shed pounds far faster than those who end conventional lifestyle plans.
Research printed in a leading health publication shows that while obese individuals often shed about a fifth of their total mass while using the jabs, the mass is regained at an estimated rate of nearly a kilo each month once they quit.
"Individuals using such drugs need to be cognizant of the danger of fast rebound weight gain when the therapy concludes," warns researcher Dr. Susan Jebb.
This pace of regain means a reversion to original mass in about one and a half years.
Weighing Therapies
The analysis, which looked at 37 of trials involving over 9,000 of patients, contrasted the outcomes of GLP-1 agonists with conventional dieting.
Researchers point out that people who shed pounds through lifestyle changes alone typically have a slower weight regain—approximately 0.1 kg a month—post-intervention.
Explaining the Quick Rebound
Nutrition scientists believe the mechanism of the injections is key to understanding the amplified regain.
GLP-1 drugs mimic a natural hormone called GLP-1, which controls feelings of fullness.
"Sustained high doses of GLP-1 concentrations far above than the body's typical production may cause the body to generate a reduced amount of its endogenous GLP-1, and may also reduce responsiveness to its actions," noted Dr. Adam Collins, a dietetics specialist.
"Withdrawal of this GLP-1 'fix' means appetite is no longer kept in check, making binge eating far more likely."
A Lifelong Issue?
The NHS advise the jabs for people with weight-linked health risks, accompanied by prescribed lifestyle changes.
Professionals argue that, given the significant potential of relapse, the treatment might need to be long-term.
This perspective is supported by drug manufacturers, who note that the results "highlight the persistent character of obesity," similar to managing diseases like hypertension.
User Experiences
Individuals who have discontinued the jabs describe a sudden return of hunger.
"It felt as if a switch flipping and you're instantly extremely hungry," recalled one woman.
This difficulty is exacerbated if individuals have not adopted permanent lifestyle or habit changes during treatment.
Widespread Adoption
Survey data show that millions of people in the UK have tried weight-loss jabs in the last 12 months, with demand continuing to grow.
- Adoption is greater among women than males.
- The 40s and 50s age group shows the greatest level of interest.
- A large proportion obtain the drugs through private healthcare rather than the NHS.
Finally, clinicians caution that while these medications are potent agents for weight loss, they are not a standalone solution and maintained weight loss relies on integrated lifestyle changes.
