A recent study suggests that people who come off blockbuster GLP-1 drugs like Mounjaro or Wegovy tend to recover lost weight at a significantly accelerated pace than those who stop conventional diet and exercise programs.
Research printed in a prominent health publication points out that while obese people can lose about a fifth of their body weight while on the medication, the weight comes back at an average rate of nearly a kilo each month once they quit.
"People buying such drugs should be cognizant of the danger of rapid weight regain when the treatment concludes," stated expert Dr. Susan Jebb.
Such speed of regain implies a reversion to pre-treatment mass in about one and a half years.
Weighing Approaches
The study, which examined dozens of studies involving thousands of patients, compared the results of the injectable medications with older methods.
Scientists point out that individuals who lose weight through lifestyle changes alone typically have a more gradual creep back—perhaps 0.1 kg a month—post-intervention.
Understanding the Rapid Rebound
Experts believe the mode of action of the jabs accounts for the amplified rebound.
GLP-1 drugs mimic a body's own chemical called GLP-1, which moderates feelings of fullness.
"Long-term administration of the hormone levels far above than normal may cause the system to produce less of its own natural hormone, and could diminish sensitivity to its actions," noted Dr. Adam Collins, a dietetics specialist.
"Discontinuation of this hormone supplement results in hunger is unsuppressed, making overeating a significant risk."
A Chronic Disease?
Medical guidelines advise the injections for individuals with obesity-related medical conditions, accompanied by prescribed lifestyle changes.
Professionals say that, considering the significant potential of weight regain, the therapy is often long-term.
This view is echoed by pharmaceutical companies, who state that the findings "underscore the long-term character of excess weight," comparing it to managing conditions like high blood pressure.
Patient Accounts
Individuals who have come off the jabs describe a intense resurgence of cravings.
"It was like something flipping and you're instantly ravenous," said an individual.
This difficulty is exacerbated if individuals have not established permanent lifestyle or habit changes during treatment.
Widespread Interest
Survey data show that millions of people in the UK have tried these injections in the past year, with demand remaining high.
- Adoption is higher among women compared to men.
- The 40s and 50s demographic shows the highest level of interest.
- Many obtain the medications through private healthcare rather than public health services.
Ultimately, clinicians emphasize that while GLP-1 drugs are effective tools for weight loss, they are not a permanent cure and maintained weight loss hinges on combined lifestyle support.
