Fresh analysis reveals that individuals who discontinue blockbuster weight-loss injections like Mounjaro or Wegovy can put back on reduced body mass far faster than those who stop traditional lifestyle plans.
Findings released in a major medical journal shows that while overweight individuals can lose about a fifth of their total mass while undergoing treatment, the weight comes back at an average rate of nearly a kilo each month upon discontinuation.
"People purchasing such medications must be cognizant of the potential of rapid rebound weight gain when the treatment ends," stated expert Dr. Susan Jebb.
This pace of recovery implies a return to original weight within about 18 months.
Comparing Treatments
The research, which examined 37 of trials involving thousands of participants, contrasted the results of GLP-1 agonists with conventional dieting.
The team emphasize that individuals who shed pounds through lifestyle changes alone usually have a less rapid creep back—perhaps 0.1 kg a month—after stopping.
Explaining the Fast Rebound
Nutrition scientists propose the mode of action of the injections is key to understanding the amplified regain.
These medications copy a body's own chemical called glucagon-like peptide-1, which moderates hunger.
"Artificially providing the hormone levels several times higher than normal could lead to the body to generate a reduced amount of its own natural GLP-1, and could diminish sensitivity to its effects," noted Dr. Adam Collins, a dietetics specialist.
"Discontinuation of this medication results in hunger is no longer kept in check, making binge eating much more probable."
An Ongoing Condition?
Health authorities recommend the injections for individuals with obesity-related health risks, accompanied by prescribed diet and exercise modifications.
Professionals argue that, due to the significant potential of relapse, the treatment should be considered long-term.
This opinion is echoed by drug manufacturers, who state that the results "emphasize the persistent nature of excess weight," similar to managing conditions like diabetes.
Patient Experiences
Users who have stopped the jabs report a intense return of cravings.
"It felt as if something that goes on and you're instantly extremely hungry," recalled one woman.
This difficulty is compounded if individuals have not developed sustainable dietary or behavioural modifications during therapy.
Growing Adoption
Recent estimates suggest that a significant number of people in the UK have used weight-loss jabs in the past year, with desire continuing to grow.
- Adoption is more common among women compared to men.
- The middle-aged age group shows the greatest usage rates.
- A large proportion access the medications through private prescriptions rather than public health services.
Finally, experts emphasize that while GLP-1 drugs are effective tools for weight loss, they are not a magic fix and lasting health benefits likely depends on combined lifestyle changes.
