Fresh analysis indicates that people who discontinue blockbuster slimming jabs like Wegovy and Mounjaro may regain shed pounds much more quickly than those who halt traditional diet and exercise regimens.
Findings released in a major medical journal shows that while obese individuals can lose about a fifth of their body weight while using the jabs, the mass is regained at an average rate of 0.8 kg per month upon discontinuation.
"Individuals purchasing such treatments should be informed of the potential of rapid weight regain when the medication concludes," stated lead investigator Dr. Susan Jebb.
This pace of regain implies a reversion to starting weight in about one and a half years.
Analyzing Therapies
The study, which looked at dozens of studies involving thousands of patients, contrasted the results of the injectable medications with other pills.
Scientists emphasize that people who lose weight through lifestyle changes alone usually experience a slower creep back—approximately 100 grams monthly—once they finish.
Understanding the Fast Regain
Doctors believe the way of the jabs is key to understanding the heightened rebound.
The injections copy a body's own chemical called GLP-1, which helps regulate feelings of fullness.
"Long-term administration of GLP-1 concentrations several times higher than normal may cause the body to produce less of its own natural hormone, and may also lessen responsiveness to its effects," noted Dr. Adam Collins, a dietetics expert.
"Discontinuation of this GLP-1 'fix' results in hunger is uncontrolled, making overeating a significant risk."
An Ongoing Condition?
The NHS suggest the injections for individuals with weight-linked health risks, accompanied by recommended lifestyle changes.
A number of clinicians argue that, due to the likelihood of relapse, the therapy might need to be ongoing.
This opinion is echoed by drug manufacturers, who say that the results "underscore the chronic nature of obesity," comparing it to managing conditions like diabetes.
User Experiences
Users who have come off the jabs describe a sudden return of appetite.
"I experienced something that goes on and you're instantly ravenous," recalled an individual.
This challenge is compounded if users have not adopted permanent lifestyle or habit changes during therapy.
Significant Use
Figures show that a significant number of adults in the UK have tried weight-loss jabs in the last 12 months, with demand being substantial.
- Use is more common among women compared to men.
- The 40s and 50s demographic shows the highest usage rates.
- Many access the drugs through private healthcare rather than public health services.
Ultimately, clinicians caution that while these medications are powerful tools for shedding pounds, they are not a magic solution and lasting health benefits relies on combined lifestyle management.
