Users Stopping Anti-Obesity Medications Gain Back Weight Far More Rapidly Compared to Dieters
A recent study suggests that patients who come off popular slimming jabs like semaglutide or tirzepatide can put back on lost weight far faster than those who halt conventional diet and exercise plans.
Published data in a major medical journal demonstrates that while overweight individuals can lose substantial amounts of their total mass while using the jabs, the weight returns at an estimated rate of nearly a kilo each month after stopping.
"People purchasing such drugs must be cognizant of the risk of quick rebound weight gain when the treatment ends," stated researcher Dr. Susan Jebb.
Such speed of regain suggests a return to pre-treatment weight in about a year and a half.
Weighing Approaches
The research, which reviewed 37 of trials involving thousands of participants, compared the outcomes of these new drugs with other pills.
Researchers point out that people who shed pounds through lifestyle changes alone generally see a slower creep back—around 100 grams monthly—after stopping.
The Reason for the Quick Regain
Experts suggest the mode of action of the jabs is key to understanding the amplified weight return.
The injections imitate a natural hormone called GLP-1, which helps regulate feelings of fullness.
"Long-term administration of GLP-1 concentrations far above than normal may cause the system to produce less of its own natural GLP-1, and could diminish sensitivity to its actions," explained Dr. Adam Collins, a nutrition researcher.
"Discontinuation of this GLP-1 'fix' means hunger is uncontrolled, making overeating far more likely."
A Lifelong Issue?
The NHS recommend the injections for individuals with weight-linked health risks, alongside recommended lifestyle changes.
Many experts say that, given the significant potential of relapse, the treatment should be considered life-long.
This perspective is supported by drug manufacturers, who state that the findings "highlight the persistent character of excess weight," comparing it to managing conditions like high blood pressure.
Patient Experiences
Users who have stopped the medication describe a sudden return of cravings.
"I experienced something that goes on and you become starving," described an individual.
The struggle is exacerbated if patients have not established lasting lifestyle or habit changes during treatment.
Growing Adoption
Figures indicate that millions of people in the UK have used these injections in the last 12 months, with interest remaining high.
- Use is greater among women compared to males.
- The 40s and 50s demographic shows the greatest usage rates.
- Many access the medications through private healthcare rather than the NHS.
Finally, clinicians emphasize that while GLP-1 drugs are powerful agents for weight loss, they are not a standalone fix and maintained weight loss likely depends on combined lifestyle management.
