New research reveals that individuals who discontinue blockbuster GLP-1 drugs like semaglutide or tirzepatide can put back on shed pounds far faster than those who halt conventional diet and exercise plans.
Published data in a prominent health publication points out that while overweight people can lose about a fifth of their body weight while undergoing treatment, the mass comes back at an average rate of nearly a kilo each month after stopping.
"Users buying such treatments must be cognizant of the risk of fast rebound weight gain when the treatment ends," cautioned lead investigator Dr. Susan Jebb.
This pace of recovery implies a reversion to pre-treatment mass in about a year and a half.
Weighing Therapies
The analysis, which reviewed dozens of trials involving over 9,000 of participants, compared the results of the injectable medications with conventional dieting.
Scientists note that people who shed pounds through lifestyle changes alone generally have a more gradual creep back—perhaps 0.1 kg a month—post-intervention.
The Reason for the Quick Regain
Nutrition scientists believe the mode of action of the injections is key to understanding the heightened weight return.
The injections copy a natural hormone called GLP-1, which helps regulate appetite.
"Sustained high doses of GLP-1 concentrations far above than the body's typical production could lead to the system to generate a reduced amount of its endogenous GLP-1, and could lessen sensitivity to its actions," explained Dr. Adam Collins, a dietetics specialist.
"Stopping of this GLP-1 'fix' means hunger is unsuppressed, making binge eating a significant risk."
A Lifelong Condition?
Medical guidelines suggest the jabs for individuals with weight-linked health risks, accompanied by prescribed lifestyle changes.
Many experts contend that, due to the likelihood of relapse, the treatment might need to be ongoing.
This view is echoed by drug manufacturers, who say that the results "emphasize the long-term character of obesity," comparing it to managing conditions like high blood pressure.
User Testimonies
Users who have come off the jabs describe a sudden resurgence of hunger.
"It felt as if something flipping and I was suddenly extremely hungry," said an individual.
This challenge is exacerbated if individuals have not established sustainable dietary or behavioural modifications during treatment.
Growing Interest
Figures indicate that millions of people in the UK have used these injections in the past year, with demand remaining high.
- Use is greater among women compared to males.
- The middle-aged demographic shows the highest level of interest.
- A large proportion access the medications through private prescriptions rather than the NHS.
In conclusion, researchers caution that while GLP-1 drugs are potent agents for weight loss, they are not a magic solution and lasting health benefits likely depends on ongoing lifestyle support.
