A recent study indicates that patients who discontinue new GLP-1 drugs like Mounjaro or Wegovy can put back on shed pounds at a significantly accelerated pace than those who stop traditional diet and exercise plans.
Findings released in a leading medical journal demonstrates that while overweight individuals often shed about a fifth of their total mass while undergoing treatment, the weight is regained at an estimated rate of nearly a kilo each month once they quit.
"Individuals buying such medications should be informed of the risk of fast rebound weight gain when the medication concludes," cautioned expert Dr. Susan Jebb.
This pace of regain implies a reversion to pre-treatment mass in about 18 months.
Weighing Approaches
The research, which looked at 37 of studies involving thousands of participants, contrasted the results of the injectable medications with conventional dieting.
Scientists emphasize that people who lose weight through diet and exercise usually have a slower weight regain—around 0.1 kg a month—once they finish.
The Reason for the Quick Regain
Nutrition scientists propose the way of the injections accounts for the heightened rebound.
The injections mimic a body's own chemical called glucagon-like peptide-1, which moderates hunger.
"Sustained high doses of the hormone concentrations several times higher than the body's typical production might result in the body to produce less of its own natural hormone, and may also reduce sensitivity to its effects," explained Dr. Adam Collins, a nutrition expert.
"Withdrawal of this hormone supplement leads to hunger is no longer kept in check, making overeating far more likely."
A Chronic Condition?
Medical guidelines recommend the injections for people with obesity-related medical conditions, alongside prescribed diet and exercise modifications.
Many experts say that, due to the significant potential of weight regain, the treatment should be considered ongoing.
This perspective is supported by pharmaceutical companies, who say that the findings "highlight the long-term character of excess weight," comparing it to managing conditions like diabetes.
Patient Accounts
People who have come off the medication explain a powerful resurgence of appetite.
"I experienced a trigger activating and you become ravenous," described one woman.
This challenge is worsened if individuals have not adopted permanent lifestyle or habit changes during treatment.
Widespread Use
Recent estimates indicate that millions of adults in the UK have tried these injections in the last 12 months, with interest continuing to grow.
- Adoption is greater among females compared to males.
- The 40s and 50s demographic shows the greatest level of interest.
- A large proportion access the medications through private prescriptions rather than public health services.
In conclusion, clinicians emphasize that while these medications are powerful agents for shedding pounds, they are not a magic cure and maintained weight loss likely depends on ongoing lifestyle support.
