A recent study indicates that people who discontinue blockbuster GLP-1 drugs like semaglutide or tirzepatide tend to recover reduced body mass far faster than those who stop traditional diet and exercise programs.
Findings released in a major health publication demonstrates that while obese people can lose about a fifth of their total mass while using the jabs, the weight returns at an estimated rate of 0.8 kg per month once they quit.
"People using these drugs should be cognizant of the potential of rapid rebound weight gain when the therapy concludes," stated lead investigator Dr. Susan Jebb.
This pace of recovery means a reversion to pre-treatment weight in about a year and a half.
Weighing Approaches
The study, which examined 37 of trials involving thousands of participants, contrasted the outcomes of GLP-1 agonists with conventional dieting.
Researchers point out that individuals who shed pounds through dieting generally have a more gradual weight regain—around 100 grams monthly—after stopping.
Explaining the Fast Rebound
Nutrition scientists propose the mode of action of the drugs accounts for the heightened rebound.
The injections copy a natural hormone called GLP-1, which helps regulate feelings of fullness.
"Long-term administration of GLP-1 levels several times higher 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 responsiveness to its actions," explained Dr. Adam Collins, a nutrition researcher.
"Withdrawal of this hormone supplement means appetite is no longer kept in check, making binge eating much more probable."
An Ongoing Issue?
Health authorities recommend the injections for people with weight-linked medical conditions, accompanied by recommended diet and exercise modifications.
A number of clinicians say that, due to the high risk of relapse, the therapy should be considered life-long.
This opinion is echoed by pharmaceutical companies, who state that the findings "underscore the chronic character of excess weight," comparing it to managing diseases like high blood pressure.
User Testimonies
Individuals who have stopped the medication describe a intense return of cravings.
"It was like something that goes on and you become starving," described one woman.
This difficulty is worsened if patients have not adopted sustainable dietary or behavioural changes during therapy.
Growing Adoption
Recent estimates indicate that a significant number of adults in the UK have used these injections in the last 12 months, with demand continuing to grow.
- Use is more common among females compared to men.
- The 40s and 50s age group shows the highest usage rates.
- Many 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 permanent solution and long-term success hinges on ongoing behavioural changes.
