New research reveals that people who discontinue popular GLP-1 drugs like semaglutide or tirzepatide tend to recover shed pounds much more quickly than those who stop traditional lifestyle programs.
Published data in a leading health publication shows that while overweight people frequently drop a large proportion of their body weight while using the jabs, the weight is regained at an estimated rate of 0.8 kg per month after stopping.
"People using these medications must be informed of the potential of fast rebound weight gain when the treatment concludes," stated researcher Dr. Susan Jebb.
That rate of recovery means a reversion to pre-treatment mass within about 18 months.
Comparing Treatments
The analysis, which reviewed 37 of studies involving thousands of participants, compared the results of GLP-1 agonists with other pills.
Researchers emphasize that people who shed pounds through lifestyle changes alone generally experience a less rapid creep back—perhaps 0.1 kg a month—after stopping.
Understanding the Fast Regain
Nutrition scientists believe the way of the jabs explains the accelerated weight return.
The injections mimic a body's own chemical called GLP-1, which controls feelings of fullness.
"Long-term administration of GLP-1 levels several times higher than normal might result in the body to produce less of its endogenous GLP-1, and could reduce responsiveness to its actions," noted Dr. Adam Collins, a nutrition specialist.
"Withdrawal of this medication leads to hunger is unsuppressed, making excessive eating far more likely."
A Chronic Disease?
Medical guidelines suggest the jabs for people with weight-linked health risks, accompanied by recommended diet and exercise modifications.
A number of clinicians say that, considering the significant potential of relapse, the treatment might need to be ongoing.
This perspective is echoed by pharmaceutical companies, who note that the findings "highlight the persistent nature of excess weight," akin to managing conditions like high blood pressure.
User Experiences
Users who have stopped the medication explain a sudden return of cravings.
"It was like a switch that goes on and I was suddenly starving," described a patient.
This challenge is worsened if patients have not adopted lasting lifestyle or habit changes during therapy.
Significant Adoption
Figures suggest that a significant number of people in the UK have used these injections in the last 12 months, with demand being substantial.
- Use is greater among women than men.
- The 40s and 50s demographic shows the highest usage rates.
- Many obtain the medications through private prescriptions rather than the NHS.
Ultimately, researchers emphasize that while the jabs are potent tools for shedding pounds, they are not a magic cure and long-term success relies on combined lifestyle management.
