Fresh analysis reveals that patients who discontinue popular weight-loss injections like semaglutide or tirzepatide may regain reduced body mass far faster than those who end conventional diet and exercise plans.
Research printed in a major health publication points out that while obese people often shed a large proportion of their body weight while undergoing treatment, the mass returns at an average rate of 0.8 kg per month once they quit.
"Individuals purchasing these treatments should be aware of the risk of quick rebound weight gain when the treatment is stopped," cautioned researcher Dr. Susan Jebb.
That rate of regain suggests a return to original mass in about one and a half years.
Analyzing Approaches
The analysis, which examined dozens of trials involving thousands of patients, contrasted the outcomes of the injectable medications with conventional dieting.
Scientists note that people who lose weight through diet and exercise generally experience a slower creep back—approximately 0.1 kg a month—once they finish.
The Reason for the Rapid Rebound
Doctors suggest the way of the drugs explains the heightened regain.
These medications mimic a natural hormone called GLP-1, which controls appetite.
"Sustained high doses of GLP-1 levels several times higher than normal may cause the body to generate a reduced amount of its own natural GLP-1, and may also lessen sensitivity to its effects," explained Dr. Adam Collins, a nutrition specialist.
"Discontinuation of this hormone supplement means appetite is uncontrolled, making binge eating much more probable."
A Lifelong Issue?
Health authorities advise the jabs for individuals with weight-linked medical conditions, accompanied by prescribed lifestyle changes.
Professionals say that, due to the likelihood of weight regain, the treatment should be considered long-term.
This perspective is echoed by pharmaceutical companies, who note that the results "underscore the persistent nature of excess weight," akin to managing diseases like diabetes.
User Testimonies
Users who have stopped the medication describe a sudden return of hunger.
"It was like a trigger flipping and I was suddenly extremely hungry," recalled one woman.
The struggle is exacerbated if users have not established sustainable dietary or behavioural changes during therapy.
Widespread Adoption
Recent estimates show that a significant number of people in the UK have used these injections in the past year, with interest being substantial.
- Adoption is higher among females compared to males.
- The middle-aged age group shows the greatest usage rates.
- Many access the drugs through private healthcare rather than public health services.
Ultimately, researchers stress that while the jabs are powerful tools for shedding pounds, they are not a permanent cure and long-term success hinges on integrated lifestyle changes.
