New research indicates that people who stop using blockbuster weight-loss injections like Wegovy and Mounjaro may regain reduced body mass far faster than those who stop traditional diet and exercise programs.
Published data in a major medical journal shows that while overweight individuals frequently drop substantial amounts of their body weight while using the jabs, the weight is regained at an average rate of 0.8 kg per month after stopping.
"Users buying such drugs should be cognizant of the danger of quick rebound weight gain when the therapy is stopped," cautioned expert Dr. Susan Jebb.
That rate of recovery implies a reversion to starting mass within about a year and a half.
Analyzing Approaches
The analysis, which reviewed dozens of trials involving over 9,000 of patients, contrasted the outcomes of these new drugs with conventional dieting.
Scientists note that individuals who lose weight through lifestyle changes alone typically have a less rapid creep back—approximately 0.1 kg a month—after stopping.
Understanding the Quick Regain
Nutrition scientists believe the way of the jabs explains the heightened regain.
The injections mimic a natural hormone called GLP-1, which helps regulate feelings of fullness.
"Artificially providing GLP-1 levels far above than the body's typical production could lead to the body to generate a reduced amount of its own natural GLP-1, and could lessen sensitivity to its effects," explained Dr. Adam Collins, a nutrition expert.
"Withdrawal of this hormone supplement means hunger is uncontrolled, making excessive eating far more likely."
An Ongoing Issue?
Medical guidelines suggest the injections for individuals with weight-linked health risks, accompanied by prescribed lifestyle changes.
Professionals say that, considering the high risk of relapse, the therapy should be considered long-term.
This opinion is supported by pharmaceutical companies, who say that the results "highlight the chronic nature of excess weight," akin to managing diseases like diabetes.
Patient Testimonies
Users who have discontinued the medication describe a powerful return of appetite.
"It was like a switch activating and you become extremely hungry," recalled a patient.
The struggle is compounded if users have not adopted lasting dietary or behavioural changes during therapy.
Widespread Use
Figures indicate that a significant number of people in the UK have tried weight-loss jabs in the last 12 months, with demand continuing to grow.
- Adoption is higher among females compared to males.
- The middle-aged age group shows the highest level of interest.
- Many access the medications through private healthcare rather than public health services.
In conclusion, researchers emphasize that while these medications are effective agents for weight loss, they are not a permanent fix and lasting health benefits relies on integrated behavioural management.
