A recent study suggests that individuals who stop using new weight-loss injections like Wegovy and Mounjaro may regain shed pounds much more quickly than those who stop conventional diet and exercise regimens.
Published data in a prominent health publication points out that while obese people often shed substantial amounts 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.
"Individuals buying such medications must be informed of the potential of fast rebound weight gain when the treatment is stopped," cautioned researcher Dr. Susan Jebb.
Such speed of regain implies a return to pre-treatment weight in about 18 months.
Weighing Therapies
The study, which reviewed 37 of trials involving over 9,000 of participants, compared the outcomes of GLP-1 agonists with conventional dieting.
Researchers point out that individuals who shed pounds through diet and exercise typically see a more gradual weight regain—approximately 100 grams monthly—once they finish.
Understanding the Rapid Regain
Doctors believe the way of the drugs accounts for the accelerated weight return.
The injections mimic a natural hormone called glucagon-like peptide-1, which helps regulate hunger.
"Sustained high doses of the hormone levels several times higher than the body's typical production might result in the system to generate a reduced amount of its own natural GLP-1, and could reduce responsiveness to its effects," noted Dr. Adam Collins, a nutrition researcher.
"Stopping of this GLP-1 'fix' results in hunger is uncontrolled, making binge eating much more probable."
A Lifelong Disease?
Health authorities advise the injections for individuals with weight-linked health risks, accompanied by prescribed diet and exercise modifications.
Many experts contend that, due to the significant potential of relapse, the therapy might need to be long-term.
This perspective is reinforced by pharmaceutical companies, who note that the results "emphasize the long-term nature of excess weight," similar to managing diseases like diabetes.
User Experiences
People who have discontinued the medication describe a intense resurgence of hunger.
"I experienced a switch activating and you're instantly extremely hungry," said a patient.
This difficulty is worsened if individuals have not adopted permanent lifestyle or habit changes during therapy.
Significant Use
Figures suggest that a significant number of adults in the UK have tried weight-loss jabs in the past year, with interest being substantial.
- Adoption is greater among women compared to males.
- The 40s and 50s demographic shows the greatest usage rates.
- Many access the medications through private prescriptions rather than public health services.
Finally, clinicians stress that while GLP-1 drugs are powerful agents for weight loss, they are not a magic cure and lasting health benefits relies on integrated lifestyle support.
