Fresh analysis suggests that people who discontinue blockbuster GLP-1 drugs like semaglutide or tirzepatide tend to recover lost weight far faster than those who stop conventional diet and exercise plans.
Findings released in a leading health publication shows that while obese people frequently drop about a fifth of their body weight while using the jabs, the mass returns at an average rate of nearly a kilo each month after stopping.
"Users buying such treatments must be aware of the potential of fast rebound weight gain when the treatment ends," stated researcher Dr. Susan Jebb.
This pace of regain means a return to original mass within about 18 months.
Comparing Approaches
The research, which examined dozens of studies involving over 9,000 of participants, contrasted the results of GLP-1 agonists with conventional dieting.
Scientists note that people who shed pounds through lifestyle changes alone generally experience a slower creep back—perhaps 100 grams monthly—post-intervention.
Understanding the Fast Rebound
Doctors believe the way of the drugs is key to understanding the heightened regain.
The injections mimic a natural hormone called GLP-1, which controls appetite.
"Sustained high doses of the hormone levels far above than normal might result in the body to produce less of its own natural GLP-1, and may also reduce sensitivity to its effects," noted Dr. Adam Collins, a dietetics expert.
"Stopping of this medication leads to appetite is uncontrolled, making binge eating a significant risk."
A Chronic Disease?
The NHS suggest the injections for individuals with weight-linked health risks, accompanied by prescribed diet and exercise modifications.
Professionals argue that, due to the significant potential of relapse, the treatment should be considered life-long.
This perspective is supported by pharmaceutical companies, who state that the findings "underscore the long-term nature of excess weight," comparing it to managing diseases like hypertension.
User Experiences
People who have come off the jabs explain a powerful resurgence of hunger.
"It felt as if something flipping and you become starving," said one woman.
This difficulty is worsened if users have not adopted sustainable lifestyle or habit changes during treatment.
Growing Adoption
Figures show that millions of adults in the UK have used these injections in the past year, with interest continuing to grow.
- Use is more common among females compared to males.
- The middle-aged demographic shows the greatest level of interest.
- A large proportion obtain the medications through private prescriptions rather than the NHS.
In conclusion, experts emphasize that while these medications are potent agents for weight loss, they are not a standalone cure and maintained weight loss hinges on ongoing lifestyle management.
