New research reveals that patients who come off popular weight-loss injections like Mounjaro or Wegovy can put back on reduced body mass far faster than those who end conventional lifestyle plans.
Findings released in a leading medical journal points out that while obese people frequently drop substantial amounts of their total mass while using the jabs, the mass is regained at an average rate of 0.8 kg per month once they quit.
"Users buying these treatments need to be aware of the danger of fast weight regain when the medication is stopped," stated lead investigator Dr. Susan Jebb.
Such speed of regain suggests a reversion to starting mass within about 18 months.
Analyzing Treatments
The analysis, which examined dozens of trials involving over 9,000 of participants, contrasted the outcomes of GLP-1 agonists with older methods.
Scientists emphasize that people who shed pounds through diet and exercise usually have a more gradual weight regain—around 0.1 kg a month—after stopping.
Explaining the Rapid Rebound
Nutrition scientists propose the mode of action of the injections explains the accelerated regain.
The injections imitate a natural hormone called glucagon-like peptide-1, which helps regulate hunger.
"Sustained high doses of the hormone concentrations several times higher than normal may cause the system to produce less of its endogenous GLP-1, and may also diminish sensitivity to its actions," said Dr. Adam Collins, a nutrition expert.
"Stopping of this hormone supplement results in hunger is no longer kept in check, making excessive eating far more likely."
A Lifelong Condition?
Medical guidelines recommend the injections for individuals with weight-linked health risks, alongside prescribed lifestyle changes.
Professionals argue that, considering the likelihood of weight regain, the therapy is often life-long.
This opinion is supported by drug manufacturers, who note that the results "underscore the persistent character of excess weight," akin to managing diseases like diabetes.
User Experiences
Individuals who have discontinued the jabs report a powerful resurgence of cravings.
"I experienced a switch flipping and you're instantly ravenous," said an individual.
This difficulty is exacerbated if individuals have not adopted sustainable lifestyle or habit changes during treatment.
Growing Use
Survey data suggest that millions of adults in the UK have tried weight-loss jabs in the last 12 months, with demand continuing to grow.
- Adoption is more common among women than males.
- The 40s and 50s demographic shows the highest level of interest.
- A large proportion access the drugs through private healthcare rather than the NHS.
Ultimately, clinicians caution that while the jabs are powerful tools for shedding pounds, they are not a permanent fix and maintained weight loss likely depends on combined lifestyle management.
