A recent study reveals that patients who come off popular GLP-1 drugs like semaglutide or tirzepatide tend to recover lost weight much more quickly than those who end conventional diet and exercise programs.
Research printed in a leading medical journal shows that while overweight individuals often shed substantial amounts of their body weight while undergoing treatment, the weight returns at an estimated rate of nearly a kilo each month upon discontinuation.
"Individuals using such medications should be informed of the potential of rapid weight regain when the medication concludes," cautioned lead investigator Dr. Susan Jebb.
That rate of regain means a reversion to pre-treatment weight in about a year and a half.
Comparing Approaches
The research, which reviewed dozens of trials involving thousands of patients, compared the effects of GLP-1 agonists with conventional dieting.
Researchers point out that people who lose weight through diet and exercise usually experience a less rapid creep back—approximately 0.1 kg a month—once they finish.
Understanding the Fast Regain
Experts suggest the way of the jabs accounts for the amplified weight return.
These medications mimic a natural hormone called GLP-1, which helps regulate hunger.
"Sustained high doses of GLP-1 concentrations far above than the body's typical production might result in the system to generate a reduced amount of its own natural GLP-1, and could lessen sensitivity to its actions," noted Dr. Adam Collins, a nutrition expert.
"Discontinuation of this GLP-1 'fix' means hunger is no longer kept in check, making binge eating far more likely."
A Chronic Condition?
Health authorities recommend the jabs for people with obesity-related medical conditions, accompanied by prescribed diet and exercise modifications.
Professionals contend that, considering the likelihood of weight regain, the therapy should be considered long-term.
This perspective is echoed by drug manufacturers, who note that the findings "highlight the persistent nature of obesity," similar to managing diseases like diabetes.
User Accounts
Individuals who have discontinued the medication describe a powerful resurgence of appetite.
"I experienced a switch flipping and you become starving," said one woman.
This difficulty is compounded if individuals have not developed sustainable lifestyle or habit changes during treatment.
Growing Interest
Survey data show that millions of people in the UK have used these injections in the last 12 months, with interest being substantial.
- Use is higher among females compared to men.
- The 40s and 50s demographic shows the highest level of interest.
- Many access the drugs through private prescriptions rather than public health services.
In conclusion, researchers emphasize that while the jabs are powerful tools for weight loss, they are not a standalone solution and maintained weight loss hinges on combined behavioural changes.
