A recent study suggests that people who stop using blockbuster GLP-1 drugs like Wegovy and Mounjaro can put back on shed pounds far faster than those who halt conventional diet and exercise regimens.
Published data in a leading health publication demonstrates that while overweight people frequently drop substantial amounts of their total mass while on the medication, the mass returns at an average rate of nearly a kilo each month after stopping.
"Users purchasing these drugs need to be aware of the risk of quick weight regain when the therapy is stopped," warns researcher Dr. Susan Jebb.
Such speed of recovery means a return to starting mass in about 18 months.
Comparing Therapies
The study, which examined dozens of trials involving thousands of participants, compared the outcomes of the injectable medications with conventional dieting.
Researchers point out that people who lose weight through dieting usually experience a slower creep back—around 100 grams monthly—post-intervention.
Understanding the Rapid Regain
Experts believe the mechanism of the injections accounts for the accelerated regain.
These medications imitate a body's own chemical called glucagon-like peptide-1, which moderates appetite.
"Artificially providing GLP-1 levels several times higher than normal might result in the system to produce less of its endogenous hormone, and may also lessen sensitivity to its effects," noted Dr. Adam Collins, a dietetics researcher.
"Stopping of this GLP-1 'fix' results in appetite is no longer kept in check, making overeating far more likely."
A Lifelong Issue?
Medical guidelines advise the injections for people with weight-linked medical conditions, alongside recommended diet and exercise modifications.
Many experts contend that, given the high risk of weight regain, the therapy is often life-long.
This perspective is reinforced by pharmaceutical companies, who state that the results "emphasize the long-term nature of excess weight," akin to managing conditions like diabetes.
Patient Experiences
People who have discontinued the medication explain a intense return of hunger.
"I experienced a trigger activating and I was suddenly ravenous," recalled an individual.
The struggle is worsened if individuals have not developed lasting dietary or behavioural changes during treatment.
Growing Interest
Survey data suggest that millions of adults in the UK have tried these injections in the last 12 months, with demand remaining high.
- Use is more common among women compared to men.
- The middle-aged demographic shows the highest usage rates.
- Many access the medications through private healthcare rather than public health services.
In conclusion, clinicians stress that while the jabs are effective agents for shedding pounds, they are not a standalone solution and maintained weight loss likely depends on combined behavioural changes.
