Fresh analysis suggests that patients who come off blockbuster weight-loss injections like Wegovy and Mounjaro tend to recover lost weight at a significantly accelerated pace than those who stop conventional lifestyle programs.
Published data in a leading medical journal demonstrates that while obese individuals can lose substantial amounts of their total mass while using the jabs, the mass comes back at an estimated rate of 0.8 kg per month upon discontinuation.
"Individuals using these treatments must be cognizant of the risk of fast weight regain when the treatment concludes," warns expert Dr. Susan Jebb.
This pace of regain suggests a return to pre-treatment weight in about one and a half years.
Comparing Treatments
The analysis, which reviewed 37 of studies involving over 9,000 of participants, contrasted the results of GLP-1 agonists with other pills.
Scientists emphasize that individuals who shed pounds through dieting usually have a more gradual creep back—approximately 0.1 kg a month—after stopping.
Understanding the Rapid Regain
Experts believe the mechanism of the drugs explains the accelerated weight return.
These medications copy a natural hormone called glucagon-like peptide-1, which helps regulate feelings of fullness.
"Sustained high doses of GLP-1 levels several times higher than normal might result in the system to produce less of its own natural hormone, and may also lessen sensitivity to its effects," said Dr. Adam Collins, a nutrition researcher.
"Discontinuation of this medication results in hunger is uncontrolled, making overeating a significant risk."
A Chronic Condition?
Medical guidelines suggest the jabs for people with weight-linked health risks, accompanied by recommended lifestyle changes.
Professionals contend that, due to the significant potential of relapse, the treatment is often ongoing.
This opinion is echoed by pharmaceutical companies, who say that the results "highlight the long-term nature of obesity," akin to managing conditions like high blood pressure.
Patient Experiences
People who have discontinued the medication explain a powerful return of appetite.
"I experienced something activating and I was suddenly extremely hungry," described one woman.
The struggle is exacerbated if individuals have not established lasting lifestyle or habit modifications during treatment.
Significant Use
Survey data show that millions of people in the UK have tried these injections in the last 12 months, with demand being substantial.
- Use is greater among females compared to males.
- The 40s and 50s demographic shows the greatest usage rates.
- Many obtain the drugs through private prescriptions rather than the NHS.
In conclusion, researchers stress that while the jabs are powerful agents for weight loss, they are not a standalone solution and long-term success relies on ongoing lifestyle changes.
