A recent study reveals that patients who discontinue popular GLP-1 drugs like Mounjaro or Wegovy tend to recover reduced body mass much more quickly than those who end conventional lifestyle regimens.
Findings released in a leading health publication shows that while obese people often shed a large proportion of their total mass while on the medication, the weight returns at an estimated rate of nearly a kilo each month after stopping.
"Users purchasing these drugs should be cognizant of the potential of fast rebound weight gain when the treatment is stopped," warns expert Dr. Susan Jebb.
That rate of regain means a return to pre-treatment mass in about one and a half years.
Comparing Therapies
The study, which looked at 37 of trials involving thousands of patients, contrasted the results of these new drugs with other pills.
Scientists point out that people who lose weight through lifestyle changes alone typically experience a less rapid weight regain—perhaps 0.1 kg a month—after stopping.
Explaining the Rapid Rebound
Experts believe the mode of action of the jabs is key to understanding the accelerated weight return.
These medications copy a natural hormone called GLP-1, which controls hunger.
"Sustained high doses of the hormone concentrations several times higher than the body's typical production could lead to the body to produce less of its own natural hormone, and could diminish responsiveness to its actions," explained Dr. Adam Collins, a dietetics expert.
"Withdrawal of this hormone supplement leads to appetite is no longer kept in check, making excessive eating a significant risk."
An Ongoing Disease?
The NHS advise the injections for people with obesity-related health risks, alongside prescribed diet and exercise modifications.
Many experts argue that, due to the significant potential of relapse, the treatment might need to be long-term.
This view is echoed by drug manufacturers, who state that the results "highlight the long-term nature of obesity," similar to managing diseases like high blood pressure.
User Testimonies
Individuals who have discontinued the medication describe a intense resurgence of hunger.
"It was like a trigger activating and you're instantly starving," recalled one woman.
This difficulty is compounded if patients have not adopted lasting dietary or behavioural modifications during therapy.
Growing Use
Survey data suggest that millions of adults in the UK have used these injections in the last 12 months, with desire being substantial.
- Adoption is higher among females than males.
- The 40s and 50s age group shows the highest level of interest.
- Many access the medications through private prescriptions rather than public health services.
Ultimately, clinicians stress that while these medications are potent agents for shedding pounds, they are not a magic cure and maintained weight loss relies on ongoing lifestyle management.
