Fresh analysis indicates that individuals who discontinue popular weight-loss injections like Wegovy and Mounjaro tend to recover lost weight at a significantly accelerated pace than those who stop traditional lifestyle programs.
Findings released in a major health publication demonstrates that while overweight people can lose substantial amounts of their total mass while undergoing treatment, the weight comes back at an average rate of nearly a kilo each month after stopping.
"People buying such treatments should be aware of the potential of rapid weight regain when the therapy ends," warns researcher Dr. Susan Jebb.
Such speed of recovery implies a reversion to pre-treatment mass in about a year and a half.
Weighing Treatments
The study, which examined dozens of trials involving thousands of participants, contrasted the outcomes of GLP-1 agonists with older methods.
Scientists emphasize that individuals who shed pounds through dieting typically experience a more gradual creep back—approximately 0.1 kg a month—once they finish.
Explaining the Rapid Regain
Experts propose the mechanism of the drugs accounts for the amplified rebound.
GLP-1 drugs mimic a body's own chemical called glucagon-like peptide-1, which moderates hunger.
"Sustained high doses of the hormone levels several times higher than the body's typical production could lead to the system to generate a reduced amount of its endogenous GLP-1, and could diminish responsiveness to its effects," noted Dr. Adam Collins, a dietetics specialist.
"Stopping of this medication means hunger is uncontrolled, making excessive eating far more likely."
An Ongoing Disease?
Health authorities recommend the jabs for people with weight-linked health risks, alongside prescribed lifestyle changes.
Many experts contend that, considering the likelihood of relapse, the treatment is often life-long.
This perspective is supported by pharmaceutical companies, who say that the results "emphasize the persistent nature of excess weight," comparing it to managing diseases like high blood pressure.
User Testimonies
Users who have discontinued the jabs describe a intense return of appetite.
"It was like a trigger that goes on and I was suddenly starving," described one woman.
This challenge is compounded if patients have not adopted sustainable dietary or behavioural modifications during treatment.
Growing Use
Figures suggest that millions of adults in the UK have used weight-loss jabs in the last 12 months, with desire being substantial.
- Use is greater among females than men.
- The middle-aged age group shows the greatest level of interest.
- Many access the medications through private healthcare rather than the NHS.
Ultimately, researchers emphasize that while these medications are potent agents for shedding pounds, they are not a standalone fix and lasting health benefits relies on integrated behavioural management.
