Fresh analysis suggests that people who stop using popular weight-loss injections like Wegovy and Mounjaro may regain lost weight far faster than those who halt traditional diet and exercise regimens.
Research printed in a prominent health publication shows that while obese people frequently drop a large proportion of their total mass while on the medication, the weight comes back at an estimated rate of 0.8 kg per month after stopping.
"Individuals purchasing these treatments should be cognizant of the danger of rapid rebound weight gain when the treatment concludes," stated expert Dr. Susan Jebb.
This pace of regain means a return to starting mass in about a year and a half.
Comparing Treatments
The study, which looked at dozens of studies involving over 9,000 of patients, compared the effects of GLP-1 agonists with conventional dieting.
The team note that people who shed pounds through lifestyle changes alone typically experience a less rapid creep back—around 100 grams monthly—post-intervention.
Understanding the Fast Regain
Nutrition scientists suggest the mode of action of the jabs is key to understanding the heightened rebound.
GLP-1 drugs copy a natural hormone called GLP-1, which moderates hunger.
"Sustained high doses of GLP-1 concentrations several times higher than the body's typical production may cause the system to generate a reduced amount of its own natural GLP-1, and could reduce sensitivity to its actions," said Dr. Adam Collins, a dietetics researcher.
"Withdrawal of this GLP-1 'fix' leads to appetite is uncontrolled, making overeating much more probable."
A Chronic Condition?
Health authorities suggest the injections for individuals with weight-linked health risks, accompanied by recommended diet and exercise modifications.
Professionals argue that, due to the significant potential of relapse, the therapy is often ongoing.
This perspective is supported by pharmaceutical companies, who say that the findings "emphasize the persistent nature of obesity," comparing it to managing diseases like high blood pressure.
User Experiences
Individuals who have discontinued the medication report a powerful return of appetite.
"It was like a trigger flipping and I was suddenly extremely hungry," described one woman.
The struggle is exacerbated if users have not developed permanent lifestyle or habit modifications during therapy.
Widespread Adoption
Survey data suggest that a significant number of people in the UK have tried weight-loss jabs in the past year, with desire being substantial.
- Use is greater among females compared to men.
- The middle-aged demographic shows the greatest usage rates.
- A large proportion obtain the medications through private prescriptions rather than the NHS.
In conclusion, researchers emphasize that while these medications are powerful tools for shedding pounds, they are not a standalone cure and long-term success likely depends on ongoing lifestyle support.
