A recent study indicates that patients who discontinue blockbuster weight-loss injections like Mounjaro or Wegovy tend to recover shed pounds much more quickly than those who end traditional diet and exercise regimens.
Published data in a major health publication demonstrates that while overweight people often shed about a fifth of their body weight while undergoing treatment, the mass comes back at an average rate of 0.8 kg per month upon discontinuation.
"Users buying these treatments must be aware of the potential of fast weight regain when the medication is stopped," cautioned lead investigator Dr. Susan Jebb.
Such speed of recovery implies a return to original mass in about a year and a half.
Analyzing Treatments
The research, which reviewed dozens of trials involving over 9,000 of participants, contrasted the outcomes of GLP-1 agonists with older methods.
Scientists note that individuals who shed pounds through dieting generally have a less rapid weight regain—approximately 0.1 kg a month—post-intervention.
The Reason for the Quick Rebound
Doctors believe the way of the injections is key to understanding the accelerated regain.
These medications copy a natural hormone called GLP-1, which controls appetite.
"Long-term administration of the hormone levels far above than the body's typical production might result in the system to produce less of its own natural hormone, and may also lessen responsiveness to its actions," noted Dr. Adam Collins, a nutrition researcher.
"Discontinuation of this medication results in hunger is unsuppressed, making excessive eating far more likely."
A Chronic Condition?
Health authorities recommend the injections for people with obesity-related health risks, accompanied by recommended lifestyle changes.
Many experts argue that, due to the likelihood of relapse, the therapy is often long-term.
This opinion is supported by drug manufacturers, who say that the findings "emphasize the persistent nature of obesity," similar to managing conditions like high blood pressure.
Patient Testimonies
People who have discontinued the medication report a intense return of hunger.
"It was like something that goes on and I was suddenly starving," described one woman.
This challenge is exacerbated if individuals have not developed lasting lifestyle or habit changes during treatment.
Growing Use
Figures show that a significant number of people in the UK have used weight-loss jabs in the past year, with demand continuing to grow.
- Use is more common among females compared to males.
- The 40s and 50s demographic shows the highest level of interest.
- Many obtain the medications through private prescriptions rather than the NHS.
Ultimately, experts emphasize that while GLP-1 drugs are powerful tools for shedding pounds, they are not a permanent solution and long-term success hinges on combined behavioural changes.
