A recent study indicates that individuals who stop using popular weight-loss injections like Wegovy and Mounjaro tend to recover reduced body mass much more quickly than those who end conventional lifestyle regimens.
Published data in a major medical journal shows that while overweight people can lose 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 after stopping.
"Users purchasing these treatments must be informed of the risk of fast rebound weight gain when the medication concludes," stated expert Dr. Susan Jebb.
That rate of regain suggests a return to pre-treatment weight in about 18 months.
Analyzing Treatments
The study, which examined dozens of studies involving thousands of patients, contrasted the outcomes of the injectable medications with other pills.
The team note that individuals who shed pounds through lifestyle changes alone generally have a more gradual creep back—perhaps 100 grams monthly—once they finish.
Explaining the Quick Regain
Doctors propose the way of the drugs explains the accelerated rebound.
These medications imitate a natural hormone called GLP-1, which moderates appetite.
"Long-term administration of the hormone concentrations several times higher than normal could lead to the body to generate a reduced amount of its endogenous hormone, and could lessen responsiveness to its effects," explained Dr. Adam Collins, a nutrition expert.
"Stopping of this medication results in hunger is no longer kept in check, making overeating a significant risk."
An Ongoing Issue?
Medical guidelines recommend the injections for individuals with weight-linked health risks, accompanied by recommended lifestyle changes.
A number of clinicians argue that, given the significant potential of relapse, the therapy should be considered ongoing.
This opinion is echoed by pharmaceutical companies, who say that the results "underscore the long-term character of obesity," comparing it to managing diseases like diabetes.
Patient Testimonies
People who have stopped the jabs describe a powerful resurgence of appetite.
"It felt as if something activating and you become ravenous," described a patient.
This difficulty is compounded if individuals have not developed permanent dietary or behavioural modifications during therapy.
Significant Interest
Figures indicate that millions of adults in the UK have used weight-loss jabs in the past year, with desire remaining high.
- Adoption is greater among women compared to males.
- The 40s and 50s age group shows the highest level of interest.
- Many access the drugs through private prescriptions rather than the NHS.
Ultimately, researchers emphasize that while the jabs are powerful tools for shedding pounds, they are not a standalone cure and long-term success relies on integrated behavioural changes.
