A recent study suggests that patients who come off blockbuster weight-loss injections like Wegovy and Mounjaro tend to recover lost weight much more quickly than those who end traditional diet and exercise plans.
Published data in a leading medical journal shows that while obese individuals frequently drop about a fifth of their body weight while undergoing treatment, the mass is regained at an average rate of 0.8 kg per month once they quit.
"People buying these treatments should be cognizant of the danger of quick weight regain when the therapy ends," stated researcher Dr. Susan Jebb.
That rate of recovery suggests a return to original weight within about a year and a half.
Analyzing Treatments
The study, which examined dozens of trials involving thousands of patients, contrasted the results of the injectable medications with conventional dieting.
Researchers point out that people who shed pounds through lifestyle changes alone typically experience a more gradual creep back—perhaps 100 grams monthly—once they finish.
The Reason for the Fast Rebound
Nutrition scientists believe the way of the jabs explains the accelerated weight return.
The injections copy a body's own chemical called GLP-1, which moderates appetite.
"Artificially providing the hormone concentrations far above than normal could lead to the system to produce less of its endogenous GLP-1, and may also diminish responsiveness to its actions," explained Dr. Adam Collins, a dietetics specialist.
"Withdrawal of this GLP-1 'fix' means hunger is no longer kept in check, making excessive eating a significant risk."
An Ongoing Disease?
Medical guidelines recommend the jabs for individuals with weight-linked health risks, accompanied by recommended lifestyle changes.
Professionals contend that, due to the likelihood of relapse, the treatment should be considered life-long.
This view is echoed by drug manufacturers, who note that the findings "emphasize the chronic nature of excess weight," akin to managing conditions like diabetes.
User Accounts
Users who have discontinued the medication report a powerful resurgence of hunger.
"I experienced a switch activating and you're instantly extremely hungry," described an individual.
This challenge is compounded if individuals have not developed sustainable lifestyle or habit changes during therapy.
Growing Interest
Figures suggest that millions of adults in the UK have used weight-loss jabs in the past year, with demand continuing to grow.
- Adoption is greater among females than men.
- The middle-aged demographic shows the greatest level of interest.
- A large proportion access the drugs through private prescriptions rather than the NHS.
Ultimately, clinicians caution that while GLP-1 drugs are powerful tools for weight loss, they are not a magic fix and lasting health benefits relies on combined lifestyle management.
