Fresh analysis suggests that individuals who come off popular GLP-1 drugs like Wegovy and Mounjaro can put back on lost weight far faster than those who halt traditional diet and exercise plans.
Published data in a leading health publication shows that while overweight individuals can lose substantial amounts of their body weight while undergoing treatment, the mass comes back at an average rate of 0.8 kg per month once they quit.
"Individuals buying these treatments need to be cognizant of the danger of quick weight regain when the treatment is stopped," warns lead investigator Dr. Susan Jebb.
Such speed of regain implies a reversion to starting mass in about one and a half years.
Weighing Therapies
The study, which examined 37 of studies involving thousands of participants, compared the effects of GLP-1 agonists with conventional dieting.
The team point out that people who lose weight through lifestyle changes alone usually experience a slower creep back—around 100 grams monthly—post-intervention.
Understanding the Rapid Regain
Doctors believe the way of the injections accounts for the accelerated weight return.
These medications copy a natural hormone called glucagon-like peptide-1, which helps regulate appetite.
"Artificially providing the hormone levels several times higher than the body's typical production could lead to the system to generate a reduced amount of its own natural hormone, and may also reduce sensitivity to its actions," said Dr. Adam Collins, a dietetics specialist.
"Withdrawal of this GLP-1 'fix' means hunger is no longer kept in check, making excessive eating far more likely."
A Lifelong Condition?
The NHS recommend the injections for people with obesity-related medical conditions, accompanied by prescribed diet and exercise modifications.
A number of clinicians argue that, due to the high risk of weight regain, the treatment should be considered long-term.
This view is reinforced by drug manufacturers, who state that the findings "underscore the persistent character of excess weight," akin to managing conditions like diabetes.
User Testimonies
People who have stopped the jabs explain a intense resurgence of appetite.
"It felt as if something flipping and I was suddenly starving," recalled an individual.
This challenge is compounded if individuals have not developed permanent lifestyle or habit modifications during therapy.
Growing Interest
Figures suggest that millions of people in the UK have tried weight-loss jabs in the last 12 months, with interest continuing to grow.
- Adoption is higher among women than men.
- The 40s and 50s demographic shows the highest usage rates.
- A large proportion obtain the medications through private prescriptions rather than the NHS.
In conclusion, researchers emphasize that while the jabs are effective tools for weight loss, they are not a standalone fix and long-term success likely depends on combined lifestyle management.
