A recent study reveals that people who come off popular GLP-1 drugs like semaglutide or tirzepatide can put back on shed pounds much more quickly than those who halt conventional lifestyle regimens.
Published data in a major health publication demonstrates that while obese people frequently drop substantial amounts of their body weight while using the jabs, the mass is regained at an average rate of nearly a kilo each month after stopping.
"People using these drugs should be informed of the potential of quick rebound weight gain when the treatment concludes," cautioned researcher Dr. Susan Jebb.
That rate of regain suggests a return to starting weight within about 18 months.
Analyzing Treatments
The research, which examined dozens of trials involving thousands of participants, compared the effects of these new drugs with other pills.
Scientists emphasize that people who lose weight through dieting usually experience a less rapid creep back—perhaps 0.1 kg a month—post-intervention.
Explaining the Quick Regain
Experts propose the mechanism of the jabs is key to understanding the accelerated regain.
These medications copy a natural hormone called glucagon-like peptide-1, which moderates hunger.
"Sustained high doses of the hormone levels far above than the body's typical production might result in the body to produce less of its own natural hormone, and could reduce responsiveness to its effects," explained Dr. Adam Collins, a nutrition specialist.
"Stopping of this hormone supplement leads to appetite is uncontrolled, making overeating much more probable."
A Lifelong Disease?
Medical guidelines advise the injections for individuals with weight-linked medical conditions, accompanied by prescribed diet and exercise modifications.
Professionals argue that, considering the likelihood of relapse, the therapy is often ongoing.
This view is echoed by pharmaceutical companies, who say that the results "emphasize the long-term nature of obesity," comparing it to managing conditions like hypertension.
User Experiences
Users who have discontinued the medication report a intense return of cravings.
"I experienced a switch activating and I was suddenly starving," said a patient.
The struggle is exacerbated if patients have not adopted permanent dietary or behavioural changes during treatment.
Significant Adoption
Survey data show that millions of adults in the UK have tried these injections in the past year, with interest continuing to grow.
- Adoption is more common among females compared to men.
- The 40s and 50s demographic shows the greatest level of interest.
- Many access the drugs through private prescriptions rather than public health services.
Finally, experts stress that while the jabs are effective tools for weight loss, they are not a magic solution and maintained weight loss hinges on combined lifestyle changes.
