Fresh analysis reveals that people who discontinue blockbuster weight-loss injections like Wegovy and Mounjaro can put back on reduced body mass far faster than those who stop traditional diet and exercise programs.
Findings released in a major health publication points out that while overweight individuals frequently drop a large proportion of their body weight while using the jabs, the weight is regained at an average rate of 0.8 kg per month once they quit.
"Individuals purchasing such medications should be aware of the danger of fast rebound weight gain when the medication concludes," warns lead investigator Dr. Susan Jebb.
This pace of recovery implies a reversion to pre-treatment mass in about 18 months.
Weighing Therapies
The study, which examined dozens of studies involving over 9,000 of patients, contrasted the effects of GLP-1 agonists with other pills.
The team note that people who shed pounds through diet and exercise typically see a more gradual creep back—approximately 0.1 kg a month—after stopping.
The Reason for the Rapid Regain
Doctors suggest the mechanism of the jabs is key to understanding the amplified rebound.
These medications mimic a natural hormone called glucagon-like peptide-1, which helps regulate appetite.
"Artificially providing the hormone levels several times higher than the body's typical production might result in the system to produce less of its endogenous GLP-1, and could reduce responsiveness to its actions," noted Dr. Adam Collins, a dietetics expert.
"Discontinuation of this medication results in appetite is unsuppressed, making excessive eating much more probable."
An Ongoing Disease?
The NHS recommend the jabs for people with weight-linked health risks, alongside recommended lifestyle changes.
Many experts say that, due to the high risk of weight regain, the therapy might need to be life-long.
This perspective is reinforced by drug manufacturers, who note that the results "emphasize the persistent character of obesity," comparing it to managing conditions like diabetes.
User Testimonies
People who have discontinued the medication report a sudden resurgence of appetite.
"I experienced a trigger activating and I was suddenly extremely hungry," described a patient.
This challenge is compounded if patients have not established lasting lifestyle or habit modifications during treatment.
Significant Interest
Survey data show that a significant number of people in the UK have tried weight-loss jabs in the past year, with demand being substantial.
- Adoption is more common among women compared to males.
- The 40s and 50s demographic shows the greatest level of interest.
- Many obtain the drugs through private healthcare rather than the NHS.
Finally, clinicians caution that while GLP-1 drugs are powerful tools for shedding pounds, they are not a permanent fix and lasting health benefits relies on combined lifestyle management.
