Fresh analysis indicates that patients who stop using blockbuster slimming jabs like Wegovy and Mounjaro tend to recover shed pounds much more quickly than those who end conventional diet and exercise regimens.
Research printed in a leading health publication shows that while obese people frequently drop a large proportion of their body weight while using the jabs, the mass is regained at an average rate of 0.8 kg per month after stopping.
"People using such medications must be informed of the danger of rapid weight regain when the medication ends," cautioned lead investigator Dr. Susan Jebb.
Such speed of regain implies a return to original mass within about a year and a half.
Comparing Treatments
The research, which reviewed dozens of trials involving thousands of patients, compared the results of GLP-1 agonists with other pills.
Scientists emphasize that people who lose weight through lifestyle changes alone typically experience a more gradual creep back—approximately 0.1 kg a month—post-intervention.
Understanding the Rapid Rebound
Nutrition scientists suggest the mode of action of the injections accounts for the heightened regain.
The injections imitate a body's own chemical called glucagon-like peptide-1, which helps regulate appetite.
"Sustained high doses of GLP-1 concentrations far above than the body's typical production may cause the body to generate a reduced amount of its own natural GLP-1, and could lessen responsiveness to its effects," said Dr. Adam Collins, a dietetics expert.
"Discontinuation of this medication means hunger is uncontrolled, making binge eating much more probable."
A Chronic Issue?
Medical guidelines suggest the jabs for people with obesity-related medical conditions, alongside recommended lifestyle changes.
Many experts contend that, due to the likelihood of relapse, the therapy is often life-long.
This view is supported by drug manufacturers, who state that the findings "highlight the long-term character of excess weight," comparing it to managing conditions like diabetes.
User Accounts
People who have stopped the medication describe a powerful resurgence of cravings.
"I experienced something flipping and you become ravenous," said a patient.
This challenge is compounded if patients have not established permanent lifestyle or habit changes during therapy.
Widespread Interest
Survey data suggest that a significant number of people in the UK have tried these injections in the last 12 months, with interest remaining high.
- Use is greater among females than men.
- The middle-aged demographic shows the highest usage rates.
- A large proportion obtain the drugs through private prescriptions rather than public health services.
In conclusion, researchers emphasize that while the jabs are potent tools for shedding pounds, they are not a standalone fix and lasting health benefits relies on integrated behavioural support.
