New research suggests that patients who stop using blockbuster slimming jabs like semaglutide or tirzepatide may regain lost weight at a significantly accelerated pace than those who end traditional diet and exercise programs.
Findings released in a prominent medical journal demonstrates that while overweight individuals can lose substantial amounts of their total mass while using the jabs, the weight returns at an average rate of nearly a kilo each month after stopping.
"Users using such drugs must be aware of the potential of quick rebound weight gain when the medication ends," stated researcher Dr. Susan Jebb.
Such speed of recovery suggests a return to starting mass within about one and a half years.
Analyzing Treatments
The study, which looked at 37 of studies involving over 9,000 of patients, contrasted the effects of GLP-1 agonists with conventional dieting.
Researchers point out that people who shed pounds through lifestyle changes alone usually have a slower creep back—approximately 0.1 kg a month—after stopping.
Understanding the Fast Rebound
Nutrition scientists propose the mode of action of the drugs accounts for the amplified weight return.
GLP-1 drugs copy a natural hormone called glucagon-like peptide-1, which helps regulate appetite.
"Sustained high doses of GLP-1 levels far above than normal may cause the body to generate a reduced amount of its own natural GLP-1, and could diminish sensitivity to its actions," said Dr. Adam Collins, a nutrition expert.
"Withdrawal of this medication means hunger is uncontrolled, making binge eating far more likely."
A Lifelong Issue?
Medical guidelines suggest the injections for people with weight-linked medical conditions, accompanied by recommended diet and exercise modifications.
Many experts contend that, due to the high risk of relapse, the therapy is often life-long.
This perspective is echoed by drug manufacturers, who state that the findings "highlight the chronic character of excess weight," comparing it to managing diseases like high blood pressure.
User Testimonies
People who have come off the jabs report a intense return of appetite.
"It was like a switch activating and you're instantly extremely hungry," said a patient.
This challenge is worsened if individuals have not established sustainable dietary or behavioural changes during treatment.
Significant Interest
Recent estimates suggest that millions of adults in the UK have tried these injections in the last 12 months, with interest remaining high.
- Use is greater among women than men.
- The middle-aged age group shows the greatest usage rates.
- Many access the drugs through private healthcare rather than the NHS.
Finally, researchers emphasize that while these medications are potent agents for weight loss, they are not a magic cure and long-term success likely depends on ongoing lifestyle management.
