New research reveals that individuals who come off popular GLP-1 drugs like Wegovy and Mounjaro can put back on shed pounds far faster than those who end traditional diet and exercise regimens.
Findings released in a leading medical journal demonstrates that while overweight people can lose substantial amounts of their body weight while on the medication, the weight returns at an estimated rate of nearly a kilo each month upon discontinuation.
"Users using these treatments need to be cognizant of the danger of fast weight regain when the therapy is stopped," cautioned expert Dr. Susan Jebb.
This pace of recovery suggests a reversion to pre-treatment mass within about one and a half years.
Comparing Treatments
The study, which examined 37 of studies involving over 9,000 of patients, contrasted the results of these new drugs with older methods.
Scientists note that people who shed pounds through lifestyle changes alone typically have a slower creep back—around 100 grams monthly—once they finish.
Understanding the Fast Regain
Nutrition scientists suggest the mechanism of the jabs is key to understanding the heightened rebound.
The injections mimic a natural hormone called glucagon-like peptide-1, which controls appetite.
"Sustained high doses of the hormone concentrations far above than normal may cause the body to produce less of its endogenous GLP-1, and could diminish sensitivity to its effects," noted Dr. Adam Collins, a dietetics expert.
"Discontinuation of this medication leads to appetite is no longer kept in check, making excessive eating far more likely."
An Ongoing Disease?
The NHS recommend the jabs for individuals with obesity-related health risks, alongside recommended lifestyle changes.
Many experts say that, given the high risk of weight regain, the therapy is often life-long.
This perspective is echoed by drug manufacturers, who say that the results "underscore the persistent character of excess weight," similar to managing conditions like diabetes.
Patient Experiences
People who have come off the jabs report a sudden return of hunger.
"I experienced a trigger flipping and you're instantly starving," described one woman.
This difficulty is compounded if individuals have not adopted permanent lifestyle or habit modifications during treatment.
Growing Adoption
Survey data suggest that a significant number of people in the UK have used these injections in the past year, with interest being substantial.
- Adoption is higher among women compared to males.
- The 40s and 50s demographic shows the highest usage rates.
- A large proportion access the medications through private prescriptions rather than the NHS.
In conclusion, clinicians emphasize that while these medications are potent tools for weight loss, they are not a magic fix and lasting health benefits relies on integrated lifestyle support.
