Fresh analysis indicates that patients who discontinue blockbuster weight-loss injections like Mounjaro or Wegovy tend to recover lost weight far faster than those who end traditional diet and exercise plans.
Published data in a major medical journal points out that while obese people often shed substantial amounts of their body weight while on the medication, the weight comes back at an estimated rate of nearly a kilo each month after stopping.
"Users buying these drugs should be aware of the potential of fast weight regain when the therapy is stopped," stated researcher Dr. Susan Jebb.
This pace of regain suggests a return to original mass within about 18 months.
Weighing Approaches
The research, which looked at dozens of studies involving thousands of participants, compared the outcomes of GLP-1 agonists with other pills.
Researchers emphasize that people who shed pounds through diet and exercise typically see a slower weight regain—perhaps 0.1 kg a month—post-intervention.
Understanding the Fast Regain
Nutrition scientists suggest the mechanism of the jabs is key to understanding the amplified rebound.
The injections imitate a natural hormone called GLP-1, which controls feelings of fullness.
"Sustained high doses 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 could lessen responsiveness to its actions," explained Dr. Adam Collins, a dietetics researcher.
"Withdrawal of this hormone supplement leads to appetite is unsuppressed, making binge eating far more likely."
A Chronic Condition?
Health authorities suggest the injections for individuals with weight-linked medical conditions, alongside recommended diet and exercise modifications.
A number of clinicians say that, given the high risk of weight regain, the therapy is often long-term.
This view is reinforced by drug manufacturers, who say that the results "underscore the long-term character of obesity," akin to managing diseases like high blood pressure.
Patient Accounts
Users who have stopped the jabs report a sudden resurgence of hunger.
"It felt as if a trigger that goes on and you're instantly starving," recalled an individual.
The struggle is exacerbated if users have not adopted permanent lifestyle or habit modifications during therapy.
Significant Interest
Figures indicate that a significant number of people in the UK have used weight-loss jabs in the last 12 months, with demand being substantial.
- Use is greater among women compared to males.
- The middle-aged age group shows the greatest level of interest.
- Many obtain the medications through private prescriptions rather than the NHS.
Ultimately, experts caution that while the jabs are effective tools for shedding pounds, they are not a standalone solution and maintained weight loss hinges on combined lifestyle support.
