A recent study reveals that people who discontinue new GLP-1 drugs like semaglutide or tirzepatide can put back on shed pounds much more quickly than those who halt conventional diet and exercise programs.
Published data in a prominent health publication demonstrates that while overweight individuals can lose substantial amounts of their body weight while on the medication, the weight comes back at an average rate of 0.8 kg per month once they quit.
"Users buying these drugs need to be cognizant of the risk of fast weight regain when the medication is stopped," warns researcher Dr. Susan Jebb.
This pace of recovery implies a reversion to pre-treatment mass within about a year and a half.
Weighing Approaches
The analysis, which examined 37 of studies involving over 9,000 of participants, compared the outcomes of the injectable medications with conventional dieting.
The team note that people who shed pounds through lifestyle changes alone typically experience a less rapid creep back—around 0.1 kg a month—post-intervention.
Explaining the Rapid Regain
Nutrition scientists propose the way of the jabs is key to understanding the heightened rebound.
The injections mimic a body's own chemical called glucagon-like peptide-1, which moderates hunger.
"Artificially providing the hormone concentrations several times higher than the body's typical production may cause the system to produce less of its endogenous GLP-1, and could lessen responsiveness to its effects," explained Dr. Adam Collins, a nutrition researcher.
"Discontinuation of this hormone supplement leads to hunger is uncontrolled, making binge eating much more probable."
An Ongoing Disease?
The NHS advise the jabs for people with weight-linked medical conditions, accompanied by prescribed lifestyle changes.
Many experts say that, due to the likelihood of relapse, the treatment is often ongoing.
This view is echoed by pharmaceutical companies, who say that the findings "emphasize the long-term nature of obesity," similar to managing conditions like hypertension.
Patient Accounts
Individuals who have stopped the medication report a intense return of appetite.
"It was like a trigger flipping and you're instantly extremely hungry," recalled an individual.
This challenge is compounded if patients have not adopted sustainable lifestyle or habit modifications during therapy.
Widespread Use
Figures indicate that millions of people in the UK have used weight-loss jabs in the past year, with demand being substantial.
- Use is greater among women than men.
- The middle-aged demographic shows the highest level of interest.
- Many obtain the drugs through private prescriptions rather than public health services.
In conclusion, experts caution that while the jabs are powerful tools for shedding pounds, they are not a permanent cure and lasting health benefits relies on integrated behavioural support.
