A recent study suggests that patients who stop using popular weight-loss injections like Wegovy and Mounjaro tend to recover lost weight much more quickly than those who halt conventional lifestyle programs.
Research printed in a leading health publication points out that while obese individuals often shed about a fifth of their total mass while using the jabs, the mass is regained at an estimated rate of 0.8 kg per month upon discontinuation.
"People using such drugs should be informed of the risk of rapid weight regain when the therapy concludes," stated lead investigator Dr. Susan Jebb.
That rate of regain suggests a return to original mass within about one and a half years.
Weighing Therapies
The analysis, which examined dozens of trials involving over 9,000 of participants, compared the effects of the injectable medications with conventional dieting.
Scientists note that individuals who lose weight through lifestyle changes alone usually see a more gradual creep back—around 0.1 kg a month—after stopping.
Explaining the Rapid Rebound
Experts propose the mode of action of the drugs accounts for the accelerated weight return.
These medications imitate a body's own chemical called GLP-1, which controls appetite.
"Artificially providing GLP-1 levels far above than the body's typical production might result in the body to produce less of its endogenous GLP-1, and may also diminish responsiveness to its effects," explained Dr. Adam Collins, a dietetics researcher.
"Discontinuation of this medication leads to hunger is uncontrolled, making overeating much more probable."
A Lifelong Issue?
Medical guidelines recommend the jabs for individuals with weight-linked health risks, accompanied by recommended diet and exercise modifications.
A number of clinicians say that, given the likelihood of weight regain, the treatment is often life-long.
This perspective is echoed by pharmaceutical companies, who note that the results "underscore the long-term character of obesity," comparing it to managing conditions like high blood pressure.
Patient Testimonies
Users who have stopped the medication report a sudden return of cravings.
"I experienced something flipping and I was suddenly starving," recalled a patient.
This challenge is compounded if individuals have not developed sustainable lifestyle or habit changes during treatment.
Significant Adoption
Survey data indicate that millions of adults in the UK have used these injections in the past year, with interest being substantial.
- Use is more common among females compared to men.
- The 40s and 50s demographic shows the highest level of interest.
- A large proportion obtain the medications through private healthcare rather than the NHS.
In conclusion, experts emphasize that while these medications are potent tools for shedding pounds, they are not a standalone fix and long-term success relies on ongoing behavioural management.
