New research suggests that individuals who discontinue popular GLP-1 drugs like semaglutide or tirzepatide may regain lost weight much more quickly than those who halt conventional lifestyle programs.
Published data in a leading medical journal demonstrates that while overweight individuals frequently drop substantial amounts of their body weight while on the medication, the weight comes back at an estimated rate of nearly a kilo each month after stopping.
"Individuals using these treatments need to be cognizant of the risk of quick rebound weight gain when the medication is stopped," cautioned expert Dr. Susan Jebb.
This pace of recovery suggests a return to original weight within about 18 months.
Comparing Therapies
The study, which examined dozens of studies involving thousands of patients, compared the results of the injectable medications with older methods.
Scientists note that individuals who shed pounds through dieting generally have a less rapid weight regain—around 100 grams monthly—once they finish.
Explaining the Fast Rebound
Experts suggest the mode of action of the jabs explains the amplified weight return.
These medications imitate a natural hormone called glucagon-like peptide-1, which helps regulate appetite.
"Artificially providing GLP-1 concentrations far above than the body's typical production may cause the body to generate a reduced amount of its own natural hormone, and may also diminish sensitivity to its effects," explained Dr. Adam Collins, a dietetics researcher.
"Stopping of this GLP-1 'fix' results in appetite is no longer kept in check, making binge eating much more probable."
A Lifelong Condition?
Medical guidelines advise the injections for people with obesity-related health risks, accompanied by recommended lifestyle changes.
Many experts argue that, considering the likelihood of relapse, the therapy should be considered ongoing.
This perspective is echoed by drug manufacturers, who state that the findings "underscore the persistent nature of obesity," comparing it to managing conditions like hypertension.
User Accounts
People who have come off the jabs describe a intense return of cravings.
"It felt as if a switch activating and I was suddenly starving," recalled an individual.
The struggle is compounded if individuals have not established lasting dietary or behavioural modifications during treatment.
Significant Interest
Recent estimates suggest that millions of people in the UK have used weight-loss jabs in the past year, with demand being substantial.
- Use is higher among women compared to men.
- The middle-aged demographic shows the greatest usage rates.
- Many obtain the drugs through private prescriptions rather than public health services.
Finally, experts emphasize that while the jabs are effective tools for weight loss, they are not a magic solution and long-term success relies on ongoing lifestyle management.
