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 halt conventional diet and exercise programs.
Findings released in a prominent health publication shows that while overweight people can lose a large proportion of their total mass while undergoing treatment, the weight returns at an average rate of nearly a kilo each month upon discontinuation.
"Users using such medications should be aware of the potential of rapid rebound weight gain when the medication concludes," warns researcher Dr. Susan Jebb.
Such speed of recovery means a return to pre-treatment weight within about 18 months.
Weighing Approaches
The analysis, which examined 37 of trials involving over 9,000 of patients, compared the effects of the injectable medications with other pills.
Researchers note that people who lose weight through diet and exercise usually have a less rapid weight regain—perhaps 100 grams monthly—after stopping.
Explaining the Rapid Rebound
Nutrition scientists suggest the mode of action of the jabs is key to understanding the heightened rebound.
These medications imitate a natural hormone called glucagon-like peptide-1, which moderates hunger.
"Artificially providing GLP-1 levels far above than normal could lead to the system to produce less of its endogenous hormone, and may also diminish responsiveness to its effects," explained Dr. Adam Collins, a nutrition researcher.
"Withdrawal of this hormone supplement results in hunger is uncontrolled, making binge eating much more probable."
An Ongoing Condition?
Health authorities suggest the jabs for people with obesity-related medical conditions, accompanied by recommended diet and exercise modifications.
Professionals contend that, considering the likelihood of weight regain, the therapy might need to be life-long.
This perspective is supported by drug manufacturers, who note that the results "underscore the chronic character of excess weight," akin to managing conditions like high blood pressure.
User Testimonies
Users who have come off the jabs explain a powerful resurgence of appetite.
"I experienced something that goes on and you become starving," recalled one woman.
This challenge is exacerbated if patients have not adopted sustainable lifestyle or habit modifications during treatment.
Growing Adoption
Figures suggest that millions of people in the UK have tried these injections in the past year, with desire continuing to grow.
- Use is higher among females than men.
- The 40s and 50s age group shows the highest level of interest.
- A large proportion access the medications through private prescriptions rather than public health services.
In conclusion, experts caution that while these medications are powerful agents for weight loss, they are not a standalone solution and lasting health benefits hinges on integrated behavioural support.
