Fresh analysis suggests that individuals who come off new GLP-1 drugs like Wegovy and Mounjaro may regain shed pounds much more quickly than those who end traditional lifestyle programs.
Published data in a major health publication demonstrates that while overweight people can lose substantial amounts of their body weight while using the jabs, the weight returns at an average rate of nearly a kilo each month once they quit.
"People buying such treatments need to be informed of the potential of fast rebound weight gain when the medication is stopped," stated researcher Dr. Susan Jebb.
This pace of recovery suggests a return to pre-treatment mass within about 18 months.
Weighing Therapies
The research, which reviewed dozens of studies involving thousands of patients, contrasted the results of the injectable medications with older methods.
Scientists note that people who lose weight through lifestyle changes alone usually see a more gradual weight regain—perhaps 100 grams monthly—post-intervention.
Understanding the Fast Regain
Nutrition scientists believe the way of the jabs is key to understanding the accelerated regain.
The injections imitate a body's own chemical called glucagon-like peptide-1, which helps regulate hunger.
"Sustained high doses of the hormone levels far above than normal might result in the body to produce less of its own natural hormone, and may also reduce responsiveness to its actions," noted Dr. Adam Collins, a nutrition expert.
"Discontinuation of this medication results in appetite is no longer kept in check, making overeating a significant risk."
A Chronic Disease?
The NHS advise the injections for people with weight-linked health risks, accompanied by prescribed diet and exercise modifications.
Professionals say that, considering the significant potential of relapse, the treatment might need to be ongoing.
This perspective is supported by drug manufacturers, who say that the findings "underscore the persistent character of excess weight," similar to managing diseases like diabetes.
User Accounts
Users who have come off the medication describe a sudden return of appetite.
"It felt as if something flipping and you're instantly extremely hungry," described an individual.
This challenge is compounded if patients have not developed permanent dietary or behavioural modifications during therapy.
Growing Adoption
Survey data indicate that a significant number of people in the UK have tried weight-loss jabs in the last 12 months, with desire remaining high.
- Adoption is more common among women than men.
- The middle-aged age group shows the greatest level of interest.
- A large proportion access the medications through private prescriptions rather than the NHS.
In conclusion, clinicians caution that while GLP-1 drugs are effective agents for weight loss, they are not a standalone solution and maintained weight loss likely depends on ongoing lifestyle management.
