New research indicates that people who stop using blockbuster weight-loss injections like semaglutide or tirzepatide can put back on shed pounds much more quickly than those who end traditional lifestyle programs.
Findings released in a leading health publication demonstrates that while overweight individuals frequently drop substantial amounts of their body weight while undergoing treatment, the weight comes back at an estimated rate of nearly a kilo each month after stopping.
"Users purchasing such drugs need to be aware of the risk of quick weight regain when the medication is stopped," stated researcher Dr. Susan Jebb.
That rate of recovery suggests a reversion to pre-treatment mass within about one and a half years.
Weighing Therapies
The analysis, which examined dozens of studies involving thousands of participants, compared the outcomes of the injectable medications with conventional dieting.
The team point out that people who shed pounds through diet and exercise generally experience a less rapid creep back—around 0.1 kg a month—after stopping.
The Reason for the Fast Rebound
Nutrition scientists suggest the mechanism of the injections accounts for the accelerated weight return.
These medications copy a body's own chemical called GLP-1, which moderates hunger.
"Sustained high doses of the hormone concentrations far above than normal could lead to the system to produce less of its own natural GLP-1, and may also diminish responsiveness to its actions," said Dr. Adam Collins, a nutrition specialist.
"Withdrawal of this hormone supplement means appetite is no longer kept in check, making excessive eating far more likely."
A Lifelong Disease?
Medical guidelines advise the injections for people with weight-linked health risks, accompanied by prescribed diet and exercise modifications.
Professionals say that, considering the high risk of relapse, the therapy might need to be ongoing.
This opinion is echoed by pharmaceutical companies, who say that the results "highlight the chronic nature of obesity," comparing it to managing diseases like diabetes.
Patient Testimonies
People who have stopped the medication explain a intense resurgence of hunger.
"I experienced a switch activating and I was suddenly ravenous," described a patient.
This challenge is compounded if patients have not established sustainable lifestyle or habit changes during treatment.
Significant Interest
Recent estimates suggest that millions of people in the UK have tried these injections in the last 12 months, with interest continuing to grow.
- Use is greater among women compared to men.
- The middle-aged demographic shows the highest usage rates.
- A large proportion access the drugs through private healthcare rather than public health services.
Ultimately, experts caution that while GLP-1 drugs are powerful agents for weight loss, they are not a magic solution and maintained weight loss relies on ongoing lifestyle changes.
