Fresh analysis indicates that individuals who discontinue popular weight-loss injections like semaglutide or tirzepatide may regain reduced body mass at a significantly accelerated pace than those who end traditional lifestyle regimens.
Findings released in a prominent health publication points out that while obese people often shed a large proportion of their body weight while on the medication, the mass returns at an average rate of 0.8 kg per month once they quit.
"Users using these medications need to be aware of the potential of fast weight regain when the treatment is stopped," stated researcher Dr. Susan Jebb.
Such speed of recovery implies a return to starting weight within about one and a half years.
Comparing Treatments
The analysis, which looked at 37 of trials involving thousands of patients, compared the effects of the injectable medications with other pills.
The team emphasize that individuals who lose weight through diet and exercise typically have a slower weight regain—approximately 0.1 kg a month—after stopping.
Understanding the Rapid Rebound
Doctors propose the mode of action of the jabs is key to understanding the amplified weight return.
The injections imitate a body's own chemical called GLP-1, which controls hunger.
"Sustained high doses of GLP-1 concentrations far above than normal might result in the system to produce less of its endogenous GLP-1, and may also reduce sensitivity to its actions," explained Dr. Adam Collins, a dietetics researcher.
"Discontinuation of this medication leads to appetite is no longer kept in check, making binge eating much more probable."
A Lifelong Condition?
Health authorities recommend the injections for people with obesity-related medical conditions, accompanied by recommended diet and exercise modifications.
Many experts argue that, due to the likelihood of weight regain, the therapy might need to be long-term.
This view is reinforced by pharmaceutical companies, who state that the findings "emphasize the chronic character of excess weight," similar to managing diseases like diabetes.
User Accounts
Users who have come off the jabs report a powerful return of cravings.
"It was like a trigger activating and I was suddenly ravenous," recalled one woman.
The struggle is exacerbated if individuals have not established sustainable lifestyle or habit changes during therapy.
Widespread Interest
Figures show that millions of people in the UK have used these injections in the last 12 months, with desire being substantial.
- Adoption is greater among women compared to men.
- The 40s and 50s age group shows the highest usage rates.
- A large proportion obtain the medications through private healthcare rather than the NHS.
Finally, experts emphasize that while the jabs are powerful agents for weight loss, they are not a magic solution and long-term success hinges on ongoing lifestyle changes.
