A recent study indicates that people who come off popular slimming jabs like Wegovy and Mounjaro tend to recover shed pounds much more quickly than those who halt conventional lifestyle regimens.
Research printed in a prominent medical journal shows that while obese individuals frequently drop a large proportion of their body weight while using the jabs, the mass is regained at an estimated rate of nearly a kilo each month once they quit.
"People buying such drugs should be cognizant of the risk of rapid rebound weight gain when the medication ends," warns researcher Dr. Susan Jebb.
This pace of recovery means a return to original weight within about a year and a half.
Weighing Treatments
The analysis, which examined 37 of trials involving thousands of patients, compared the effects of the injectable medications with other pills.
Researchers note that people who shed pounds through lifestyle changes alone usually have a more gradual creep back—approximately 0.1 kg a month—post-intervention.
The Reason for the Fast Rebound
Doctors believe the way of the jabs explains the amplified rebound.
The injections copy a natural hormone called glucagon-like peptide-1, which helps regulate feelings of fullness.
"Artificially providing the hormone concentrations several times higher than normal may cause the body to produce less of its endogenous hormone, and may also lessen responsiveness to its actions," said Dr. Adam Collins, a dietetics researcher.
"Discontinuation of this GLP-1 'fix' leads to hunger is uncontrolled, making overeating far more likely."
An Ongoing Issue?
Health authorities recommend the injections for people with obesity-related health risks, alongside recommended lifestyle changes.
A number of clinicians argue that, given the likelihood of relapse, the therapy might need to be life-long.
This opinion is reinforced by drug manufacturers, who state that the findings "underscore the chronic nature of obesity," comparing it to managing diseases like diabetes.
Patient Accounts
Users who have discontinued the medication report a sudden return of hunger.
"It was like a switch flipping and I was suddenly extremely hungry," said a patient.
This challenge is exacerbated if patients have not developed sustainable lifestyle or habit modifications during treatment.
Widespread Adoption
Survey data show that a significant number of people in the UK have used these injections in the last 12 months, with desire remaining high.
- Adoption is more common among females than males.
- The 40s and 50s demographic shows the greatest level of interest.
- A large proportion access the medications through private healthcare rather than the NHS.
Ultimately, researchers stress that while these medications are potent agents for shedding pounds, they are not a magic cure and lasting health benefits relies on combined behavioural management.
