A recent study indicates that people who come off popular GLP-1 drugs like Wegovy and Mounjaro can put back on reduced body mass far faster than those who stop conventional lifestyle programs.
Findings released in a major medical journal shows that while obese people frequently drop a large proportion of their body weight while using the jabs, the mass comes back at an estimated rate of nearly a kilo each month after stopping.
"Individuals buying such medications should be cognizant of the danger of quick weight regain when the therapy is stopped," warns lead investigator Dr. Susan Jebb.
Such speed of recovery implies a return to starting weight within about a year and a half.
Analyzing Approaches
The analysis, which examined dozens of trials involving thousands of participants, contrasted the outcomes of these new drugs with older methods.
Scientists point out that individuals who shed pounds through lifestyle changes alone generally experience a slower weight regain—around 100 grams monthly—post-intervention.
The Reason for the Quick Regain
Doctors believe the mode of action of the drugs explains the amplified weight return.
The injections copy a natural hormone called glucagon-like peptide-1, which moderates hunger.
"Long-term administration of GLP-1 levels far above than the body's typical production may cause the body to produce less of its own natural GLP-1, and could reduce responsiveness to its actions," explained Dr. Adam Collins, a dietetics expert.
"Discontinuation of this hormone supplement results in appetite is no longer kept in check, making excessive eating far more likely."
A Lifelong Disease?
Medical guidelines recommend the injections for individuals with weight-linked medical conditions, accompanied by recommended diet and exercise modifications.
A number of clinicians say that, due to the significant potential of weight regain, the therapy should be considered life-long.
This opinion is echoed by pharmaceutical companies, who say that the findings "emphasize the chronic character of obesity," akin to managing conditions like high blood pressure.
Patient Experiences
Individuals who have come off the medication describe a intense resurgence of appetite.
"I experienced a trigger flipping and you become starving," described an individual.
This difficulty is exacerbated if users have not adopted sustainable lifestyle or habit changes during treatment.
Widespread Use
Figures indicate that a significant number of people in the UK have tried these injections in the past year, with desire being substantial.
- Adoption is more common among women than males.
- The middle-aged demographic shows the highest level of interest.
- Many access the medications through private prescriptions rather than the NHS.
Finally, researchers emphasize that while these medications are effective tools for weight loss, they are not a permanent fix and lasting health benefits likely depends on integrated behavioural changes.
