Fresh analysis suggests that individuals who stop using popular GLP-1 drugs like semaglutide or tirzepatide may regain lost weight much more quickly than those who halt conventional diet and exercise plans.
Findings released in a prominent health publication demonstrates that while overweight individuals often shed a large proportion of their total mass while using the jabs, the weight comes back at an estimated rate of 0.8 kg per month upon discontinuation.
"Individuals using such medications must be informed of the potential of fast rebound weight gain when the therapy is stopped," cautioned expert Dr. Susan Jebb.
That rate of recovery suggests a return to original mass within about a year and a half.
Comparing Approaches
The analysis, which looked at 37 of trials involving thousands of participants, contrasted the effects of these new drugs with other pills.
Researchers note that people who shed pounds through diet and exercise usually have a slower creep back—approximately 100 grams monthly—once they finish.
The Reason for the Quick Regain
Experts suggest the way of the jabs explains the accelerated regain.
GLP-1 drugs imitate a body's own chemical called GLP-1, which moderates feelings of fullness.
"Long-term administration of the hormone levels several times higher than normal might result in the body to produce less of its endogenous GLP-1, and may also diminish responsiveness to its actions," explained Dr. Adam Collins, a nutrition researcher.
"Stopping of this medication leads to appetite is unsuppressed, making binge eating much more probable."
An Ongoing Disease?
Health authorities recommend the jabs for people with obesity-related medical conditions, accompanied by prescribed diet and exercise modifications.
Many experts argue that, due to the significant potential of relapse, the therapy should be considered ongoing.
This perspective is supported by pharmaceutical companies, who say that the results "highlight the chronic character of excess weight," akin to managing diseases like hypertension.
Patient Testimonies
People who have come off the jabs describe a sudden resurgence of cravings.
"I experienced a switch activating and you become starving," recalled a patient.
This challenge is worsened if users have not established permanent lifestyle or habit changes during therapy.
Significant Use
Figures suggest that millions of people in the UK have used these injections in the past year, with desire continuing to grow.
- Adoption is more common among women than males.
- The 40s and 50s demographic shows the greatest usage rates.
- A large proportion obtain the medications through private prescriptions rather than the NHS.
Finally, researchers caution that while the jabs are potent tools for weight loss, they are not a magic fix and maintained weight loss relies on combined lifestyle changes.
