A recent study reveals that individuals who stop using blockbuster GLP-1 drugs like semaglutide or tirzepatide may regain reduced body mass at a significantly accelerated pace than those who halt conventional lifestyle regimens.
Findings released in a major medical journal demonstrates that while overweight people frequently drop substantial amounts of their total mass while on the medication, the mass returns at an average rate of 0.8 kg per month after stopping.
"Individuals using these treatments should be informed of the danger of fast weight regain when the therapy concludes," stated expert Dr. Susan Jebb.
Such speed of regain means a reversion to starting weight within about one and a half years.
Comparing Treatments
The research, which examined dozens of studies involving thousands of participants, compared the effects of the injectable medications with other pills.
Scientists note that people who shed pounds through diet and exercise typically see a more gradual weight regain—perhaps 100 grams monthly—once they finish.
Understanding the Quick Regain
Doctors propose the mechanism of the injections explains the accelerated regain.
GLP-1 drugs mimic a natural hormone called GLP-1, which moderates feelings of fullness.
"Sustained high doses of GLP-1 levels far above than the body's typical production could lead to the system to generate a reduced amount of its endogenous GLP-1, and may also reduce responsiveness to its actions," explained Dr. Adam Collins, a dietetics specialist.
"Stopping of this hormone supplement leads to appetite is uncontrolled, making binge eating far more likely."
A Chronic Disease?
Medical guidelines advise the jabs for individuals with obesity-related health risks, accompanied by prescribed diet and exercise modifications.
Many experts argue that, given the likelihood of relapse, the therapy should be considered ongoing.
This view is reinforced by drug manufacturers, who say that the results "highlight the long-term character of excess weight," akin to managing diseases like hypertension.
Patient Testimonies
Individuals who have discontinued the jabs describe a powerful resurgence of hunger.
"It felt as if a trigger activating and you're instantly ravenous," described one woman.
The struggle is worsened if individuals have not developed lasting lifestyle or habit modifications during treatment.
Widespread Use
Figures show that millions of adults in the UK have tried these injections in the last 12 months, with interest continuing to grow.
- Use is greater among women compared to males.
- The middle-aged age group shows the greatest usage rates.
- Many access the drugs through private prescriptions rather than public health services.
Finally, clinicians stress that while GLP-1 drugs are powerful agents for weight loss, they are not a standalone cure and lasting health benefits hinges on integrated behavioural changes.
