A recent study suggests that people who discontinue new weight-loss injections like Wegovy and Mounjaro can put back on shed pounds at a significantly accelerated pace than those who end traditional lifestyle regimens.
Findings released in a major medical journal shows that while obese individuals often shed substantial amounts of their body weight while undergoing treatment, the weight comes back at an estimated rate of 0.8 kg per month once they quit.
"Users buying such drugs need to be informed of the potential of quick weight regain when the medication is stopped," cautioned expert Dr. Susan Jebb.
That rate of regain suggests a reversion to original weight within about 18 months.
Analyzing Treatments
The analysis, which reviewed dozens of studies involving thousands of participants, contrasted the effects of GLP-1 agonists with older methods.
Scientists note that people who shed pounds through diet and exercise typically see a more gradual creep back—perhaps 100 grams monthly—once they finish.
Explaining the Quick Regain
Experts suggest the mechanism of the injections is key to understanding the accelerated weight return.
GLP-1 drugs mimic a body's own chemical called GLP-1, which helps regulate hunger.
"Sustained high doses of GLP-1 levels far above than the body's typical production may cause the system to produce less of its own natural hormone, and may also lessen sensitivity to its effects," explained Dr. Adam Collins, a nutrition expert.
"Discontinuation of this hormone supplement results in hunger is no longer kept in check, making overeating far more likely."
A Chronic Issue?
Health authorities recommend the jabs for people with obesity-related health risks, accompanied by recommended lifestyle changes.
A number of clinicians argue that, considering the significant potential of weight regain, the therapy might need to be life-long.
This perspective is reinforced by drug manufacturers, who say that the results "underscore the chronic nature of excess weight," similar to managing diseases like diabetes.
User Experiences
People who have stopped the jabs describe a powerful resurgence of cravings.
"It was like a trigger that goes on and I was suddenly extremely hungry," recalled a patient.
This challenge is worsened if patients have not adopted sustainable lifestyle or habit changes during treatment.
Growing Use
Figures suggest that a significant number of adults in the UK have tried weight-loss jabs in the last 12 months, with desire being substantial.
- Adoption is higher among females compared to men.
- The middle-aged demographic shows the highest usage rates.
- Many access the medications through private healthcare rather than public health services.
Ultimately, experts caution that while GLP-1 drugs are effective tools for shedding pounds, they are not a permanent cure and maintained weight loss hinges on ongoing lifestyle changes.
