Fresh analysis suggests that patients who stop using blockbuster weight-loss injections like Wegovy and Mounjaro tend to recover lost weight at a significantly accelerated pace than those who end traditional diet and exercise plans.
Published data in a leading medical journal demonstrates that while obese individuals can lose substantial amounts of their body weight while using the jabs, the weight comes back at an average rate of nearly a kilo each month upon discontinuation.
"People buying these medications should be cognizant of the danger of quick weight regain when the medication concludes," stated researcher Dr. Susan Jebb.
Such speed of regain implies a reversion to starting weight within about a year and a half.
Comparing Therapies
The study, which reviewed 37 of trials involving thousands of participants, contrasted the effects of GLP-1 agonists with conventional dieting.
The team point out that individuals who shed pounds through lifestyle changes alone usually have a less rapid weight regain—approximately 0.1 kg a month—post-intervention.
Understanding the Quick Regain
Doctors suggest the mode of action of the injections explains the amplified weight return.
The injections mimic a body's own chemical called glucagon-like peptide-1, which helps regulate appetite.
"Sustained high doses of GLP-1 levels far above than normal may cause the body to produce less of its endogenous GLP-1, and could diminish responsiveness to its effects," explained Dr. Adam Collins, a nutrition expert.
"Discontinuation of this GLP-1 'fix' leads to appetite is no longer kept in check, making binge eating far more likely."
A Chronic Issue?
The NHS advise the jabs for individuals with obesity-related medical conditions, accompanied by prescribed diet and exercise modifications.
A number of clinicians contend that, due to the significant potential of relapse, the therapy is often long-term.
This perspective is echoed by drug manufacturers, who note that the findings "underscore the chronic nature of obesity," similar to managing diseases like high blood pressure.
Patient Testimonies
Individuals who have discontinued the jabs explain a intense return of appetite.
"I experienced a switch flipping and you're instantly ravenous," said an individual.
This challenge is exacerbated if individuals have not established permanent dietary or behavioural changes during therapy.
Significant Interest
Survey data show that millions of people in the UK have used weight-loss jabs in the past year, with interest continuing to grow.
- Use is higher among women compared to males.
- The 40s and 50s age group shows the highest level of interest.
- A large proportion access the medications through private healthcare rather than the NHS.
Finally, clinicians stress that while GLP-1 drugs are powerful agents for weight loss, they are not a permanent solution and long-term success likely depends on combined lifestyle changes.
