Fresh analysis reveals that people who come off blockbuster GLP-1 drugs like Wegovy and Mounjaro may regain shed pounds far faster than those who halt conventional lifestyle plans.
Findings released in a prominent health publication demonstrates that while overweight people often shed a large proportion of their body weight while using the jabs, the mass comes back at an estimated rate of nearly a kilo each month once they quit.
"Users buying such medications should be informed of the danger of rapid weight regain when the therapy ends," cautioned lead investigator Dr. Susan Jebb.
That rate of recovery implies a reversion to pre-treatment mass within about a year and a half.
Weighing Therapies
The analysis, which reviewed 37 of studies involving over 9,000 of participants, compared the results of GLP-1 agonists with older methods.
The team emphasize that individuals who lose weight through lifestyle changes alone usually experience a more gradual weight regain—approximately 100 grams monthly—post-intervention.
The Reason for the Fast Rebound
Doctors propose the mode of action of the drugs accounts for the heightened rebound.
These medications imitate a natural hormone called glucagon-like peptide-1, which controls hunger.
"Sustained high doses of the hormone concentrations several times higher than the body's typical production may cause the body to produce less of its own natural hormone, and may also lessen sensitivity to its actions," said Dr. Adam Collins, a dietetics expert.
"Stopping of this medication leads to hunger is uncontrolled, making binge eating far more likely."
A Lifelong Issue?
The NHS suggest the injections for individuals with weight-linked health risks, accompanied by prescribed diet and exercise modifications.
Many experts argue that, given the high risk of weight regain, the therapy is often ongoing.
This perspective is echoed by drug manufacturers, who note that the findings "highlight the persistent character of obesity," akin to managing conditions like hypertension.
Patient Experiences
People who have discontinued the jabs explain a intense return of cravings.
"It was like a trigger activating and I was suddenly starving," said a patient.
The struggle is worsened if users have not developed lasting dietary or behavioural modifications during therapy.
Widespread Use
Survey data suggest that millions of people in the UK have tried these injections in the last 12 months, with demand remaining high.
- Use is greater among women than males.
- The 40s and 50s demographic shows the greatest usage rates.
- A large proportion access the drugs through private healthcare rather than public health services.
In conclusion, clinicians caution that while the jabs are effective tools for shedding pounds, they are not a permanent cure and long-term success hinges on integrated lifestyle changes.
