New research reveals that individuals who come off blockbuster weight-loss injections like semaglutide or tirzepatide can put back on reduced body mass at a significantly accelerated pace than those who halt traditional diet and exercise plans.
Findings released in a leading health publication shows that while overweight people often shed substantial amounts of their total mass while using the jabs, the weight returns at an estimated rate of 0.8 kg per month once they quit.
"Users using such drugs must be cognizant of the potential of fast weight regain when the therapy concludes," cautioned expert Dr. Susan Jebb.
Such speed of regain suggests a reversion to pre-treatment weight within about one and a half years.
Weighing Treatments
The analysis, which reviewed 37 of studies involving thousands of participants, compared the effects of these new drugs with older methods.
Scientists point out that people who lose weight through diet and exercise generally have a slower creep back—around 0.1 kg a month—once they finish.
Explaining the Rapid Rebound
Doctors believe the mechanism of the drugs is key to understanding the heightened regain.
The injections imitate a natural hormone called GLP-1, which helps regulate hunger.
"Sustained high doses of the hormone levels far above than normal could lead to the system to generate a reduced amount of its own natural hormone, and may also lessen sensitivity to its effects," said Dr. Adam Collins, a dietetics researcher.
"Stopping of this hormone supplement leads to appetite is unsuppressed, making overeating much more probable."
A Chronic Condition?
Medical guidelines advise the jabs for individuals with obesity-related medical conditions, accompanied by recommended lifestyle changes.
Many experts say that, considering the high risk of weight regain, the treatment is often ongoing.
This perspective is reinforced by pharmaceutical companies, who state that the results "underscore the chronic character of excess weight," akin to managing conditions like diabetes.
User Testimonies
Users who have come off the medication explain a intense return of cravings.
"It was like a switch activating and you become extremely hungry," recalled an individual.
This difficulty is exacerbated if patients have not adopted sustainable dietary or behavioural changes during treatment.
Growing Interest
Recent estimates show that a significant number of people in the UK have used these injections in the past year, with desire continuing to grow.
- Adoption is higher among women compared to males.
- The middle-aged demographic shows the highest level of interest.
- Many access the medications through private healthcare rather than the NHS.
Ultimately, researchers emphasize that while GLP-1 drugs are effective tools for shedding pounds, they are not a standalone cure and long-term success relies on combined lifestyle management.
