Fresh analysis indicates that individuals who stop using popular GLP-1 drugs like Wegovy and Mounjaro may regain shed pounds at a significantly accelerated pace than those who stop conventional diet and exercise programs.
Research printed in a major health publication demonstrates that while obese individuals often shed a large proportion of their body weight while undergoing treatment, the mass comes back at an estimated rate of 0.8 kg per month after stopping.
"Users using such treatments should be cognizant of the potential of rapid weight regain when the therapy is stopped," stated expert Dr. Susan Jebb.
That rate of regain implies a reversion to original mass within about one and a half years.
Comparing Treatments
The research, which looked at 37 of trials involving thousands of patients, contrasted the effects of these new drugs with other pills.
Scientists emphasize that individuals who shed pounds through dieting typically experience a slower creep back—around 0.1 kg a month—after stopping.
The Reason for the Quick Regain
Experts suggest the way of the injections accounts for the amplified weight return.
GLP-1 drugs copy a body's own chemical called glucagon-like peptide-1, which controls appetite.
"Sustained high doses of the hormone levels several times higher than normal may cause the body to generate a reduced amount of its endogenous hormone, and could reduce sensitivity to its effects," noted Dr. Adam Collins, a dietetics expert.
"Discontinuation of this medication leads to appetite is unsuppressed, making binge eating far more likely."
A Lifelong Disease?
Health authorities recommend the injections for individuals with weight-linked medical conditions, alongside recommended lifestyle changes.
Professionals say that, due to the likelihood of relapse, the treatment should be considered ongoing.
This perspective is reinforced by pharmaceutical companies, who note that the results "emphasize the persistent nature of obesity," akin to managing diseases like diabetes.
Patient Accounts
People who have discontinued the medication describe a intense return of hunger.
"It felt as if a switch that goes on and you're instantly starving," described one woman.
The struggle is worsened if users have not adopted lasting dietary or behavioural changes during treatment.
Significant Use
Recent estimates indicate that a significant number of people in the UK have tried these injections in the past year, with interest being substantial.
- Use is higher among females than men.
- The 40s and 50s age group shows the greatest usage rates.
- Many obtain the drugs through private healthcare rather than the NHS.
In conclusion, clinicians caution that while GLP-1 drugs are powerful agents for weight loss, they are not a magic cure and maintained weight loss hinges on integrated lifestyle changes.
