Fresh analysis indicates that patients who come off popular slimming jabs like semaglutide or tirzepatide can put back on shed pounds at a significantly accelerated pace than those who halt traditional diet and exercise plans.
Findings released in a leading medical journal demonstrates that while obese people can lose substantial amounts of their total mass while undergoing treatment, the weight is regained at an average rate of 0.8 kg per month once they quit.
"People using such medications should be informed of the risk of fast weight regain when the medication is stopped," stated researcher Dr. Susan Jebb.
Such speed of recovery suggests a reversion to pre-treatment mass in about 18 months.
Analyzing Therapies
The research, which examined dozens of studies involving thousands of participants, contrasted the results of GLP-1 agonists with conventional dieting.
Scientists note that individuals who lose weight through diet and exercise typically have a less rapid weight regain—approximately 0.1 kg a month—after stopping.
Explaining the Fast Regain
Nutrition scientists suggest the way of the drugs is key to understanding the accelerated rebound.
The injections imitate a body's own chemical called GLP-1, which moderates appetite.
"Long-term administration of GLP-1 levels far above than the body's typical production may cause the system to produce less of its own natural GLP-1, and could reduce responsiveness to its actions," explained Dr. Adam Collins, a nutrition specialist.
"Withdrawal of this GLP-1 'fix' results in appetite is unsuppressed, making binge eating far more likely."
A Lifelong Disease?
Health authorities advise the injections for individuals with obesity-related health risks, alongside recommended lifestyle changes.
A number of clinicians argue that, due to the likelihood of weight regain, the therapy is often life-long.
This perspective is supported by pharmaceutical companies, who note that the results "emphasize the long-term nature of excess weight," similar to managing conditions like high blood pressure.
User Accounts
People who have come off the jabs report a powerful return of appetite.
"It felt as if a switch activating and I was suddenly starving," recalled an individual.
This difficulty is worsened if users have not developed sustainable lifestyle or habit changes during therapy.
Significant Adoption
Figures indicate that a significant number of people in the UK have used weight-loss jabs in the last 12 months, with interest continuing to grow.
- Use is more common among women than men.
- The middle-aged demographic shows the highest usage rates.
- Many obtain the medications through private prescriptions rather than the NHS.
Finally, clinicians stress that while these medications are potent agents for shedding pounds, they are not a magic cure and lasting health benefits likely depends on combined lifestyle changes.
