Fresh analysis indicates that patients who stop using popular weight-loss injections like semaglutide or tirzepatide tend to recover shed pounds much more quickly than those who halt traditional diet and exercise plans.
Research printed in a prominent health publication demonstrates that while overweight people can lose about a fifth of their total mass while undergoing treatment, the weight is regained at an estimated rate of nearly a kilo each month once they quit.
"People purchasing such drugs should be informed of the potential of rapid rebound weight gain when the medication ends," stated researcher Dr. Susan Jebb.
Such speed of regain means a reversion to original weight within about one and a half years.
Weighing Therapies
The study, which looked at 37 of trials involving thousands of patients, contrasted the outcomes of the injectable medications with other pills.
Scientists emphasize that people who lose weight through dieting typically experience a slower creep back—around 100 grams monthly—once they finish.
The Reason for the Quick Rebound
Experts suggest the mechanism of the drugs accounts for the amplified weight return.
These medications mimic a body's own chemical called glucagon-like peptide-1, which moderates appetite.
"Sustained high doses of GLP-1 levels far above than the body's typical production could lead to the body to generate a reduced amount of its own natural GLP-1, and could diminish sensitivity to its actions," explained Dr. Adam Collins, a dietetics researcher.
"Stopping of this medication leads to hunger is no longer kept in check, making binge eating far more likely."
A Chronic Disease?
Health authorities advise the injections for individuals with obesity-related medical conditions, alongside prescribed lifestyle changes.
Professionals say that, considering the significant potential of weight regain, the therapy might need to be life-long.
This perspective is echoed by drug manufacturers, who state that the findings "highlight the persistent nature of excess weight," similar to managing diseases like high blood pressure.
Patient Testimonies
Users who have come off the medication report a powerful resurgence of cravings.
"It felt as if something flipping and you're instantly starving," said an individual.
The struggle is worsened if individuals have not developed lasting dietary or behavioural changes during therapy.
Growing Use
Survey data show that a significant number of people in the UK have tried these injections in the past year, with interest remaining high.
- Use is more common among females than males.
- The middle-aged age group shows the highest usage rates.
- A large proportion obtain the drugs through private healthcare rather than public health services.
Ultimately, clinicians stress that while the jabs are effective agents for shedding pounds, they are not a magic solution and lasting health benefits relies on integrated lifestyle management.
