A recent study suggests that individuals who stop using popular weight-loss injections like semaglutide or tirzepatide may regain shed pounds far faster than those who stop traditional lifestyle plans.
Research printed in a major medical journal demonstrates that while overweight people can lose substantial amounts of their total mass while undergoing treatment, the mass is regained at an estimated rate of 0.8 kg per month upon discontinuation.
"Users buying these medications need to be aware of the risk of fast rebound weight gain when the medication ends," warns expert Dr. Susan Jebb.
Such speed of regain implies a return to starting mass in about a year and a half.
Weighing Therapies
The research, which looked at dozens of studies involving over 9,000 of participants, compared the outcomes of GLP-1 agonists with conventional dieting.
Researchers note that individuals who shed pounds through diet and exercise typically have a more gradual creep back—around 100 grams monthly—once they finish.
The Reason for the Rapid Rebound
Nutrition scientists propose the mode of action of the injections is key to understanding the accelerated weight return.
The injections mimic a natural hormone called GLP-1, which helps regulate appetite.
"Long-term administration of GLP-1 concentrations far above than normal may cause the body to generate a reduced amount of its own natural hormone, and could reduce responsiveness to its actions," noted Dr. Adam Collins, a nutrition researcher.
"Stopping of this medication means appetite is uncontrolled, making excessive eating far more likely."
An Ongoing Condition?
Health authorities recommend the injections for people with weight-linked medical conditions, accompanied by prescribed diet and exercise modifications.
Professionals contend that, considering the high risk of weight regain, the therapy might need to be life-long.
This opinion is reinforced by pharmaceutical companies, who say that the findings "underscore the long-term nature of excess weight," similar to managing diseases like high blood pressure.
User Testimonies
Users who have discontinued the medication describe a intense resurgence of hunger.
"I experienced something that goes on and you're instantly extremely hungry," described an individual.
This difficulty is worsened if individuals have not developed sustainable lifestyle or habit modifications during treatment.
Growing Interest
Figures indicate that millions of people in the UK have tried these injections in the past year, with interest remaining high.
- Use is more common among women compared to males.
- The middle-aged age group shows the highest usage rates.
- Many obtain the drugs through private healthcare rather than the NHS.
Ultimately, clinicians stress that while these medications are powerful agents for shedding pounds, they are not a magic solution and long-term success likely depends on combined lifestyle management.
