A recent study indicates that people who come off popular GLP-1 drugs like semaglutide or tirzepatide can put back on lost weight much more quickly than those who halt traditional lifestyle programs.
Published data in a leading health publication points out that while overweight individuals often shed substantial amounts of their body weight while on the medication, the mass returns at an average rate of nearly a kilo each month after stopping.
"People purchasing such treatments should be aware of the potential of rapid weight regain when the medication ends," stated expert Dr. Susan Jebb.
Such speed of regain implies a reversion to pre-treatment weight within about 18 months.
Weighing Approaches
The research, which examined dozens of studies involving thousands of participants, compared the outcomes of the injectable medications with older methods.
Researchers emphasize that individuals who shed pounds through dieting generally experience a slower weight regain—approximately 0.1 kg a month—once they finish.
Understanding the Fast Regain
Doctors believe the way of the jabs is key to understanding the heightened rebound.
The injections mimic a natural hormone called GLP-1, which controls feelings of fullness.
"Sustained high doses of GLP-1 concentrations several times higher than the body's typical production could lead to the system to produce less of its endogenous hormone, and may also diminish sensitivity to its actions," explained Dr. Adam Collins, a nutrition researcher.
"Withdrawal of this medication results in hunger is uncontrolled, making binge eating much more probable."
A Chronic Disease?
Health authorities recommend the jabs for people with obesity-related health risks, alongside recommended diet and exercise modifications.
Professionals contend that, given the high risk of weight regain, the therapy is often life-long.
This view is supported by pharmaceutical companies, who state that the results "highlight the chronic nature of obesity," similar to managing diseases like high blood pressure.
User Experiences
Users who have come off the jabs describe a sudden return of cravings.
"It felt as if something that goes on and you become ravenous," said an individual.
This challenge is exacerbated if individuals have not developed permanent dietary or behavioural modifications during treatment.
Growing Interest
Recent estimates suggest that a significant number of people in the UK have tried weight-loss jabs in the last 12 months, with interest remaining high.
- Adoption is more common among women compared to males.
- The middle-aged age group shows the highest usage rates.
- A large proportion obtain the drugs through private prescriptions rather than public health services.
In conclusion, researchers stress that while GLP-1 drugs are powerful agents for weight loss, they are not a magic solution and long-term success relies on integrated behavioural management.
