Fresh analysis reveals that people who stop using new weight-loss injections like semaglutide or tirzepatide may regain reduced body mass far faster than those who halt conventional lifestyle programs.
Findings released in a leading medical journal points out that while obese people can lose a large proportion of their total mass while undergoing treatment, the mass comes back at an average rate of 0.8 kg per month after stopping.
"People using such treatments should be cognizant of the potential of fast weight regain when the therapy concludes," cautioned lead investigator Dr. Susan Jebb.
This pace of recovery means a return to original mass in about 18 months.
Analyzing Treatments
The research, which looked at 37 of studies involving thousands of patients, compared the results of GLP-1 agonists with older methods.
The team emphasize that individuals who shed pounds through lifestyle changes alone generally see a more gradual creep back—perhaps 100 grams monthly—after stopping.
Understanding the Rapid Rebound
Nutrition scientists suggest the mechanism of the injections explains the heightened rebound.
These medications imitate a natural hormone called glucagon-like peptide-1, which helps regulate feelings of fullness.
"Artificially providing the hormone levels several times higher than normal might result in the system to produce less of its endogenous hormone, and may also diminish sensitivity to its effects," said Dr. Adam Collins, a nutrition researcher.
"Stopping of this medication means appetite is no longer kept in check, making excessive eating much more probable."
A Chronic Disease?
The NHS suggest the injections for people with weight-linked medical conditions, accompanied by recommended diet and exercise modifications.
Professionals argue that, given the high risk of weight regain, the therapy should be considered life-long.
This view is supported by drug manufacturers, who state that the findings "underscore the chronic nature of obesity," akin to managing diseases like diabetes.
User Experiences
Users who have come off the medication describe a intense return of hunger.
"I experienced a switch activating and you become starving," recalled an individual.
This difficulty is worsened if individuals have not established sustainable lifestyle or habit modifications during therapy.
Widespread Adoption
Recent estimates show that millions of adults in the UK have used these injections in the past year, with desire being substantial.
- Use is greater among women compared to men.
- The middle-aged age group shows the greatest usage rates.
- Many access the drugs through private prescriptions rather than public health services.
In conclusion, clinicians emphasize that while the jabs are powerful agents for shedding pounds, they are not a permanent solution and lasting health benefits relies on combined lifestyle support.
