A recent study indicates that patients who discontinue new GLP-1 drugs like semaglutide or tirzepatide can put back on lost weight far faster than those who end traditional diet and exercise plans.
Findings released in a major medical journal demonstrates that while overweight individuals frequently drop a large proportion of their total mass while on the medication, the weight is regained at an estimated rate of 0.8 kg per month upon discontinuation.
"Individuals buying such drugs must be aware of the risk of fast rebound weight gain when the treatment concludes," stated expert Dr. Susan Jebb.
That rate of recovery implies a return to original weight within about one and a half years.
Weighing Approaches
The study, which looked at dozens of studies involving thousands of patients, compared the results of the injectable medications with other pills.
Researchers point out that people who lose weight through dieting usually see a more gradual weight regain—around 100 grams monthly—once they finish.
The Reason for the Quick Rebound
Experts believe the way of the drugs is key to understanding the amplified rebound.
GLP-1 drugs copy a body's own chemical called glucagon-like peptide-1, which moderates appetite.
"Artificially providing the hormone levels several times higher than the body's typical production may cause the body to produce less of its endogenous GLP-1, and could reduce responsiveness to its actions," explained Dr. Adam Collins, a dietetics specialist.
"Withdrawal of this hormone supplement means appetite is unsuppressed, making excessive eating a significant risk."
A Lifelong Disease?
Health authorities recommend the injections for individuals with weight-linked medical conditions, alongside prescribed diet and exercise modifications.
Many experts contend that, given the significant potential of weight regain, the treatment should be considered ongoing.
This perspective is echoed by pharmaceutical companies, who note that the findings "underscore the persistent character of obesity," comparing it to managing conditions like diabetes.
Patient Testimonies
People who have come off the medication report a intense resurgence of appetite.
"It felt as if a switch activating and I was suddenly ravenous," said a patient.
The struggle is exacerbated if patients have not developed permanent dietary or behavioural changes during therapy.
Significant Adoption
Recent estimates show that a significant number of adults in the UK have tried weight-loss jabs in the last 12 months, with demand continuing to grow.
- Adoption is more common among women compared to men.
- The 40s and 50s demographic shows the greatest level of interest.
- Many access the medications through private healthcare rather than public health services.
Finally, experts emphasize that while these medications are effective tools for shedding pounds, they are not a permanent solution and long-term success hinges on ongoing lifestyle management.
