A recent study reveals that people who come off new weight-loss injections like Wegovy and Mounjaro tend to recover reduced body mass far faster than those who halt conventional lifestyle regimens.
Published data in a major health publication demonstrates that while obese people frequently drop about a fifth of their body weight while using the jabs, the mass comes back at an estimated rate of 0.8 kg per month once they quit.
"Individuals purchasing these medications must be informed of the danger of fast rebound weight gain when the treatment ends," warns lead investigator Dr. Susan Jebb.
That rate of regain implies a return to starting weight in about one and a half years.
Analyzing Therapies
The analysis, which examined dozens of trials involving thousands of participants, contrasted the outcomes of the injectable medications with conventional dieting.
Researchers note that people who shed pounds through dieting generally have a less rapid creep back—around 100 grams monthly—after stopping.
Explaining the Quick Rebound
Doctors suggest the mechanism of the jabs explains the heightened regain.
These medications mimic a natural hormone called GLP-1, which controls hunger.
"Artificially providing the hormone concentrations far above than normal may cause the body to produce less of its own natural GLP-1, and may also lessen responsiveness to its actions," explained Dr. Adam Collins, a nutrition specialist.
"Stopping of this GLP-1 'fix' results in hunger is unsuppressed, making overeating far more likely."
An Ongoing Condition?
Health authorities recommend the injections for people with weight-linked medical conditions, alongside recommended diet and exercise modifications.
Professionals contend that, due to the likelihood of relapse, the treatment should be considered long-term.
This view is supported by pharmaceutical companies, who say that the results "underscore the chronic nature of excess weight," akin to managing conditions like high blood pressure.
Patient Testimonies
People who have discontinued the jabs explain a intense return of hunger.
"It was like a switch that goes on and I was suddenly ravenous," recalled a patient.
This challenge is worsened if patients have not adopted permanent dietary or behavioural modifications during treatment.
Widespread Use
Survey data show that millions of people in the UK have tried weight-loss jabs in the last 12 months, with desire being substantial.
- Adoption is more common among women than males.
- The middle-aged age group shows the greatest level of interest.
- A large proportion obtain the medications through private healthcare rather than the NHS.
Finally, researchers stress that while the jabs are powerful agents for weight loss, they are not a permanent fix and lasting health benefits hinges on ongoing behavioural management.
