A recent study indicates that individuals who discontinue popular GLP-1 drugs like Wegovy and Mounjaro can put back on shed pounds at a significantly accelerated pace than those who stop traditional lifestyle regimens.
Published data in a leading medical journal points out that while overweight individuals often shed a large proportion of their total mass while on the medication, the weight is regained at an average rate of 0.8 kg per month once they quit.
"Individuals purchasing such medications should be aware of the risk of quick rebound weight gain when the treatment ends," stated researcher Dr. Susan Jebb.
This pace of regain suggests a reversion to starting mass within about a year and a half.
Analyzing Approaches
The analysis, which looked at dozens of studies involving over 9,000 of patients, compared the outcomes of GLP-1 agonists with other pills.
Scientists emphasize that people who shed pounds through lifestyle changes alone typically see a less rapid creep back—around 0.1 kg a month—once they finish.
The Reason for the Rapid Rebound
Nutrition scientists propose the mode of action of the jabs is key to understanding the amplified weight return.
These medications mimic a body's own chemical called GLP-1, which controls appetite.
"Long-term administration of GLP-1 concentrations far above than normal might result in the system to produce less of its endogenous hormone, and may also lessen responsiveness to its effects," said Dr. Adam Collins, a nutrition specialist.
"Discontinuation of this hormone supplement means hunger is no longer kept in check, making excessive eating a significant risk."
An Ongoing Condition?
The NHS recommend the injections for individuals with weight-linked health risks, alongside recommended lifestyle changes.
A number of clinicians say that, considering the likelihood of relapse, the therapy is often ongoing.
This view is supported by drug manufacturers, who say that the findings "highlight the persistent nature of excess weight," akin to managing conditions like diabetes.
User Accounts
Individuals who have come off the medication describe a intense resurgence of hunger.
"I experienced something flipping and you're instantly starving," said a patient.
This difficulty is compounded if users have not adopted permanent dietary or behavioural changes during therapy.
Growing Use
Recent estimates show that a significant number of adults in the UK have used weight-loss jabs in the past year, with interest remaining high.
- Use is greater among women than males.
- The 40s and 50s age group shows the greatest level of interest.
- Many access the medications through private healthcare rather than the NHS.
Ultimately, clinicians caution that while the jabs are powerful tools for shedding pounds, they are not a magic fix and lasting health benefits likely depends on combined lifestyle support.
