A recent study indicates that individuals who discontinue popular GLP-1 drugs like semaglutide or tirzepatide tend to recover reduced body mass at a significantly accelerated pace than those who end traditional diet and exercise plans.
Published data in a leading medical journal demonstrates that while obese people often shed substantial amounts of their body weight while using the jabs, the weight returns at an estimated rate of nearly a kilo each month once they quit.
"Users buying these medications should be cognizant of the potential of rapid rebound weight gain when the therapy ends," stated expert Dr. Susan Jebb.
That rate of recovery means a return to pre-treatment mass within about one and a half years.
Analyzing Treatments
The study, which reviewed 37 of trials involving thousands of patients, compared the effects of GLP-1 agonists with other pills.
Scientists point out that people who lose weight through diet and exercise usually see a less rapid weight regain—around 0.1 kg a month—post-intervention.
The Reason for the Fast Rebound
Doctors propose the mode of action of the jabs is key to understanding the accelerated regain.
These medications mimic a natural hormone called glucagon-like peptide-1, which controls feelings of fullness.
"Artificially providing the hormone concentrations several times higher than normal may cause the body to produce less of its endogenous hormone, and could reduce responsiveness to its effects," said Dr. Adam Collins, a dietetics expert.
"Stopping of this hormone supplement leads to appetite is unsuppressed, making overeating far more likely."
A Lifelong Disease?
Health authorities recommend the jabs for individuals with obesity-related health risks, accompanied by recommended lifestyle changes.
A number of clinicians say that, due to the significant potential of relapse, the therapy should be considered ongoing.
This opinion is echoed by pharmaceutical companies, who state that the results "emphasize the persistent nature of obesity," comparing it to managing conditions like hypertension.
User Accounts
Users who have stopped the jabs explain a powerful return of appetite.
"It was like a trigger that goes on and I was suddenly starving," said an individual.
This difficulty is compounded if individuals have not developed permanent lifestyle or habit modifications during therapy.
Widespread Interest
Figures suggest that a significant number of people in the UK have tried these injections in the last 12 months, with demand continuing to grow.
- Use is greater among women compared to males.
- The 40s and 50s age group shows the greatest level of interest.
- A large proportion access the drugs through private prescriptions rather than the NHS.
Finally, researchers caution that while the jabs are powerful tools for shedding pounds, they are not a permanent solution and lasting health benefits likely depends on combined lifestyle support.
