Fresh analysis indicates that people who stop using blockbuster weight-loss injections like Wegovy and Mounjaro can put back on reduced body mass at a significantly accelerated pace than those who end traditional lifestyle programs.
Research printed in a prominent health publication points out that while overweight individuals can lose substantial amounts of their total mass while using the jabs, the mass comes back at an average rate of nearly a kilo each month after stopping.
"People purchasing such drugs need to be cognizant of the potential of quick weight regain when the therapy concludes," stated expert Dr. Susan Jebb.
That rate of recovery implies a return to starting weight in about 18 months.
Analyzing Therapies
The research, which examined dozens of trials involving over 9,000 of participants, compared the results of GLP-1 agonists with conventional dieting.
The team note that individuals who lose weight through lifestyle changes alone typically see a slower creep back—approximately 100 grams monthly—post-intervention.
Understanding the Quick Rebound
Experts propose the mode of action of the jabs explains the amplified regain.
The injections mimic a body's own chemical called GLP-1, which controls appetite.
"Long-term administration of the hormone concentrations several times higher than normal could lead to the body to generate a reduced amount of its own natural hormone, and could lessen sensitivity to its actions," explained Dr. Adam Collins, a nutrition expert.
"Withdrawal of this medication means hunger is no longer kept in check, making excessive eating much more probable."
A Chronic Disease?
The NHS advise the injections for people with obesity-related medical conditions, alongside recommended diet and exercise modifications.
A number of clinicians contend that, due to the significant potential of relapse, the treatment is often long-term.
This opinion is reinforced by drug manufacturers, who state that the results "underscore the persistent nature of excess weight," comparing it to managing diseases like diabetes.
Patient Testimonies
People who have discontinued the jabs report a intense resurgence of cravings.
"It was like a switch activating and you become ravenous," recalled an individual.
The struggle is exacerbated if patients have not developed lasting dietary or behavioural changes during therapy.
Growing Use
Survey data show that millions of adults in the UK have used these injections in the past year, with desire continuing to grow.
- Use is higher among women than men.
- The middle-aged age group shows the highest level of interest.
- Many access the drugs through private prescriptions rather than the NHS.
Ultimately, researchers emphasize that while GLP-1 drugs are potent agents for weight loss, they are not a magic cure and lasting health benefits hinges on combined behavioural changes.
