Fresh analysis suggests that people who come off blockbuster GLP-1 drugs like Wegovy and Mounjaro may regain shed pounds much more quickly than those who stop traditional diet and exercise programs.
Published data in a prominent medical journal demonstrates that while overweight individuals can lose about a fifth of their total mass while using the jabs, the weight returns at an estimated rate of 0.8 kg per month upon discontinuation.
"Individuals purchasing these drugs need to be informed of the risk of fast rebound weight gain when the medication concludes," warns lead investigator Dr. Susan Jebb.
That rate of recovery means a reversion to pre-treatment mass within about one and a half years.
Weighing Approaches
The analysis, which examined 37 of studies involving over 9,000 of patients, contrasted the effects of GLP-1 agonists with other pills.
The team emphasize that people who shed pounds through dieting generally experience a slower weight regain—perhaps 100 grams monthly—once they finish.
Understanding the Quick Regain
Nutrition scientists propose the mode of action of the drugs accounts for the heightened regain.
GLP-1 drugs imitate a body's own chemical called GLP-1, which moderates appetite.
"Artificially providing the hormone levels far above than the body's typical production may cause the system to generate a reduced amount of its own natural GLP-1, and could lessen sensitivity to its effects," said Dr. Adam Collins, a nutrition expert.
"Discontinuation of this GLP-1 'fix' results in appetite is unsuppressed, making excessive eating far more likely."
A Lifelong Disease?
Health authorities suggest the injections for individuals with obesity-related medical conditions, alongside prescribed diet and exercise modifications.
Professionals argue that, considering the likelihood of relapse, the therapy should be considered long-term.
This view is reinforced by drug manufacturers, who state that the findings "highlight the chronic character of excess weight," comparing it to managing diseases like hypertension.
Patient Experiences
Individuals who have come off the medication report a intense return of appetite.
"It was like a switch flipping and you become starving," described an individual.
This challenge is exacerbated if patients have not adopted permanent lifestyle or habit modifications during treatment.
Significant Use
Recent estimates suggest that a significant number of adults in the UK have tried these injections in the last 12 months, with desire remaining high.
- Use is higher among women compared to males.
- The 40s and 50s age group shows the greatest usage rates.
- A large proportion obtain the drugs through private healthcare rather than public health services.
In conclusion, experts emphasize that while these medications are potent agents for shedding pounds, they are not a magic cure and long-term success hinges on combined lifestyle management.
