A recent study indicates that individuals who come off new GLP-1 drugs like semaglutide or tirzepatide can put back on shed pounds far faster than those who stop traditional diet and exercise regimens.
Research printed in a prominent health publication shows that while overweight individuals often shed a large proportion of their body weight while undergoing treatment, the weight returns at an estimated rate of nearly a kilo each month once they quit.
"Users using these medications must be aware of the risk of fast rebound weight gain when the therapy ends," stated expert Dr. Susan Jebb.
That rate of recovery means a return to original weight in about a year and a half.
Analyzing Treatments
The study, which looked at 37 of trials involving thousands of patients, contrasted the outcomes of GLP-1 agonists with other pills.
Scientists emphasize that people who lose weight through lifestyle changes alone generally have a more gradual creep back—around 100 grams monthly—once they finish.
Explaining the Quick Rebound
Nutrition scientists believe the mode of action of the injections is key to understanding the amplified rebound.
The injections imitate a body's own chemical called glucagon-like peptide-1, which helps regulate hunger.
"Artificially providing GLP-1 levels far above than normal could lead to the system to produce less of its endogenous GLP-1, and may also reduce responsiveness to its actions," said Dr. Adam Collins, a nutrition expert.
"Stopping of this medication means appetite is uncontrolled, making excessive eating much more probable."
A Lifelong Disease?
Health authorities advise the jabs for people with obesity-related medical conditions, alongside recommended diet and exercise modifications.
Professionals argue that, due to the high risk of weight regain, the therapy is often life-long.
This opinion is reinforced by drug manufacturers, who say that the findings "highlight the long-term nature of obesity," similar to managing conditions like diabetes.
User Testimonies
Individuals who have discontinued the medication describe a sudden resurgence of hunger.
"I experienced a switch that goes on and I was suddenly ravenous," said an individual.
This difficulty is compounded if patients have not established permanent lifestyle or habit changes during treatment.
Significant Use
Recent estimates suggest that a significant number of adults in the UK have tried these injections in the last 12 months, with interest being substantial.
- Use is higher among women than men.
- The 40s and 50s demographic shows the highest usage rates.
- Many obtain the drugs through private healthcare rather than public health services.
Finally, researchers stress that while the jabs are powerful tools for shedding pounds, they are not a permanent cure and lasting health benefits hinges on integrated behavioural support.
