New research reveals that patients who come off popular GLP-1 drugs like Mounjaro or Wegovy can put back on lost weight far faster than those who stop conventional lifestyle regimens.
Findings released in a major medical journal points out that while obese individuals frequently drop a large proportion of their body weight while on the medication, the mass returns at an estimated rate of nearly a kilo each month upon discontinuation.
"People purchasing such treatments must be informed of the potential of rapid weight regain when the therapy concludes," cautioned researcher Dr. Susan Jebb.
Such speed of recovery means a reversion to starting weight in about one and a half years.
Analyzing Treatments
The study, which looked at 37 of trials involving thousands of participants, contrasted the results of these new drugs with other pills.
The team note that people who shed pounds through lifestyle changes alone typically see a slower creep back—around 100 grams monthly—once they finish.
Understanding the Rapid Regain
Nutrition scientists propose the way of the drugs explains the amplified weight return.
The injections copy a natural hormone called glucagon-like peptide-1, which moderates feelings of fullness.
"Sustained high doses of GLP-1 levels far above than normal could lead to the body to generate a reduced amount of its endogenous GLP-1, and may also diminish responsiveness to its effects," noted Dr. Adam Collins, a dietetics researcher.
"Stopping of this GLP-1 'fix' means appetite is no longer kept in check, making overeating much more probable."
A Lifelong Issue?
The NHS suggest the jabs for people with obesity-related health risks, accompanied by recommended lifestyle changes.
A number of clinicians argue that, due to the high risk of weight regain, the treatment is often long-term.
This view is supported by drug manufacturers, who state that the results "underscore the chronic character of excess weight," akin to managing conditions like high blood pressure.
User Testimonies
People who have stopped the medication describe a powerful resurgence of hunger.
"I experienced something flipping and you're instantly starving," recalled a patient.
This difficulty is compounded if individuals have not established permanent lifestyle or habit changes during therapy.
Growing Use
Survey data suggest that millions of people in the UK have tried these injections in the last 12 months, with desire being substantial.
- Use is more common among women than males.
- The 40s and 50s age group shows the highest usage rates.
- Many obtain the medications through private prescriptions rather than public health services.
In conclusion, experts caution that while the jabs are potent tools for weight loss, they are not a permanent fix and maintained weight loss likely depends on combined behavioural management.
