A recent study reveals that patients who stop using popular GLP-1 drugs like Mounjaro or Wegovy can put back on reduced body mass far faster than those who end conventional diet and exercise regimens.
Published data in a leading health publication shows that while overweight people frequently drop about a fifth of their body weight while undergoing treatment, the weight is regained at an average rate of 0.8 kg per month once they quit.
"Users using such treatments must be cognizant of the risk of rapid rebound weight gain when the treatment ends," warns expert Dr. Susan Jebb.
That rate of regain suggests a reversion to pre-treatment mass within about one and a half years.
Comparing Therapies
The study, which looked at dozens of studies involving over 9,000 of participants, contrasted the outcomes of these new drugs with older methods.
Researchers emphasize that individuals who shed pounds through lifestyle changes alone generally have a slower weight regain—approximately 0.1 kg a month—once they finish.
Understanding the Quick Regain
Doctors believe the way of the jabs accounts for the heightened rebound.
The injections mimic a body's own chemical called glucagon-like peptide-1, which moderates feelings of fullness.
"Artificially providing GLP-1 concentrations several times higher than normal may cause the system to produce less of its own natural hormone, and could diminish responsiveness to its actions," explained Dr. Adam Collins, a nutrition specialist.
"Discontinuation of this GLP-1 'fix' means hunger is unsuppressed, making overeating far more likely."
A Lifelong Disease?
Medical guidelines recommend the injections for people with weight-linked health risks, accompanied by recommended diet and exercise modifications.
A number of clinicians contend that, considering the significant potential of weight regain, the treatment is often long-term.
This perspective is echoed by pharmaceutical companies, who say that the results "underscore the long-term nature of excess weight," akin to managing conditions like high blood pressure.
User Accounts
Individuals who have discontinued the medication report a intense resurgence of cravings.
"It felt as if something that goes on and you become starving," described one woman.
This challenge is compounded if individuals have not developed sustainable lifestyle or habit modifications during therapy.
Significant Interest
Survey data indicate that a significant number of people in the UK have used weight-loss jabs in the last 12 months, with interest continuing to grow.
- Use is greater among women compared to males.
- The 40s and 50s demographic shows the greatest usage rates.
- A large proportion obtain the medications through private prescriptions rather than the NHS.
Ultimately, researchers stress that while these medications are effective tools for shedding pounds, they are not a magic solution and long-term success hinges on combined behavioural management.
