A recent study reveals that people who discontinue blockbuster GLP-1 drugs like Wegovy and Mounjaro may regain reduced body mass at a significantly accelerated pace than those who halt traditional lifestyle regimens.
Published data in a prominent health publication demonstrates that while obese individuals frequently drop a large proportion of their body weight while undergoing treatment, the mass returns at an average rate of 0.8 kg per month after stopping.
"People using these drugs need to be aware of the danger of rapid rebound weight gain when the medication is stopped," warns lead investigator Dr. Susan Jebb.
Such speed of recovery implies a return to original weight within about 18 months.
Comparing Treatments
The study, which examined dozens of trials involving over 9,000 of patients, compared the effects of GLP-1 agonists with older methods.
Researchers note that individuals who shed pounds through dieting typically have a more gradual creep back—perhaps 100 grams monthly—after stopping.
Understanding the Quick Regain
Doctors suggest the mechanism of the jabs explains the heightened regain.
GLP-1 drugs mimic a natural hormone called GLP-1, which moderates hunger.
"Long-term administration of the hormone levels several times higher than the body's typical production may cause the system to generate a reduced amount of its own natural GLP-1, and may also diminish sensitivity to its effects," noted Dr. Adam Collins, a dietetics specialist.
"Discontinuation of this medication leads to hunger is no longer kept in check, making overeating a significant risk."
An Ongoing Issue?
Health authorities recommend the jabs for individuals with obesity-related medical conditions, alongside recommended lifestyle changes.
Many experts say that, considering the likelihood of weight regain, the therapy might need to be life-long.
This view is reinforced by drug manufacturers, who note that the findings "highlight the persistent nature of excess weight," similar to managing conditions like high blood pressure.
User Accounts
Users who have stopped the medication report a powerful resurgence of cravings.
"It was like a switch flipping and you're instantly extremely hungry," recalled an individual.
The struggle is compounded if users have not developed permanent dietary or behavioural changes during therapy.
Significant Use
Figures indicate that millions of adults in the UK have tried these injections in the past year, with demand continuing to grow.
- Adoption is greater among women than males.
- The 40s and 50s age group shows the highest usage rates.
- Many obtain the medications through private prescriptions rather than the NHS.
In conclusion, experts caution that while GLP-1 drugs are powerful tools for shedding pounds, they are not a permanent cure and long-term success likely depends on combined lifestyle changes.
