A recent study suggests that patients who come off new slimming jabs like Wegovy and Mounjaro may regain shed pounds far faster than those who stop traditional lifestyle plans.
Findings released in a prominent health publication demonstrates that while obese individuals can lose a large proportion of their total mass while on the medication, the mass returns at an estimated rate of 0.8 kg per month after stopping.
"People purchasing such treatments must be informed of the danger of rapid rebound weight gain when the medication concludes," cautioned researcher Dr. Susan Jebb.
This pace of regain implies a return to original mass within about one and a half years.
Comparing Approaches
The research, which reviewed dozens of trials involving thousands of patients, contrasted the outcomes of GLP-1 agonists with older methods.
Scientists point out that individuals who shed pounds through diet and exercise typically see a slower weight regain—approximately 100 grams monthly—after stopping.
Understanding the Rapid Regain
Experts believe the mechanism of the drugs is key to understanding the heightened weight return.
GLP-1 drugs imitate a natural hormone called glucagon-like peptide-1, which helps regulate appetite.
"Artificially providing the hormone levels far above than the body's typical production may cause the body to generate a reduced amount of its own natural hormone, and may also lessen sensitivity to its effects," explained Dr. Adam Collins, a nutrition expert.
"Discontinuation of this GLP-1 'fix' leads to hunger is uncontrolled, making excessive eating much more probable."
A Lifelong Disease?
The NHS advise the injections for people with weight-linked medical conditions, accompanied by recommended lifestyle changes.
Many experts say that, given the significant potential of relapse, the therapy should be considered life-long.
This perspective is reinforced by pharmaceutical companies, who note that the results "underscore the long-term nature of excess weight," similar to managing diseases like diabetes.
Patient Accounts
People who have come off the medication describe a intense return of hunger.
"I experienced a switch activating and you're instantly starving," said a patient.
This challenge is compounded if patients have not adopted sustainable dietary or behavioural changes during treatment.
Significant Use
Survey data suggest that millions of people in the UK have tried these injections in the past year, with interest remaining high.
- Use is higher among females than men.
- The 40s and 50s age group shows the highest usage rates.
- Many obtain the medications through private healthcare rather than public health services.
Finally, experts emphasize that while these medications are powerful tools for weight loss, they are not a magic fix and lasting health benefits hinges on ongoing lifestyle changes.
