Fresh analysis suggests that individuals who discontinue blockbuster GLP-1 drugs like Wegovy and Mounjaro can put back on shed pounds far faster than those who halt conventional lifestyle regimens.
Findings released in a leading medical journal demonstrates that while obese people often shed about a fifth of their body weight while on the medication, the mass is regained at an estimated rate of nearly a kilo each month upon discontinuation.
"Individuals buying these drugs need to be aware of the danger of quick rebound weight gain when the medication concludes," stated expert Dr. Susan Jebb.
This pace of regain suggests a reversion to original mass in about one and a half years.
Analyzing Therapies
The study, which looked at dozens of studies involving thousands of participants, compared the outcomes of these new drugs with older methods.
The team point out that individuals who shed pounds through dieting generally see a slower weight regain—perhaps 0.1 kg a month—post-intervention.
Explaining the Quick Regain
Experts believe the mechanism of the injections explains the heightened weight return.
GLP-1 drugs copy a natural hormone called glucagon-like peptide-1, which moderates hunger.
"Sustained high doses of the hormone concentrations far above than the body's typical production might result in the system to generate a reduced amount of its endogenous hormone, and could lessen sensitivity to its effects," explained Dr. Adam Collins, a dietetics expert.
"Withdrawal of this hormone supplement leads to hunger is unsuppressed, making overeating a significant risk."
A Chronic Issue?
The NHS suggest the injections for individuals with weight-linked health risks, accompanied by prescribed diet and exercise modifications.
Many experts argue that, given the significant potential of relapse, the therapy should be considered life-long.
This view is echoed by drug manufacturers, who note that the results "underscore the chronic nature of excess weight," akin to managing diseases like diabetes.
Patient Testimonies
People who have stopped the medication report a powerful return of cravings.
"It felt as if a switch activating and you become starving," recalled a patient.
This difficulty is compounded if patients have not developed sustainable lifestyle or habit changes during treatment.
Significant Adoption
Recent estimates show that millions of adults in the UK have used these injections in the last 12 months, with desire remaining high.
- Adoption is higher among females compared to males.
- The 40s and 50s age group shows the highest usage rates.
- A large proportion access the drugs through private healthcare rather than the NHS.
Ultimately, clinicians caution that while these medications are effective tools for shedding pounds, they are not a standalone cure and maintained weight loss likely depends on integrated lifestyle support.
