A recent study indicates that patients who stop using popular weight-loss injections like Mounjaro or Wegovy tend to recover lost weight at a significantly accelerated pace than those who stop conventional lifestyle regimens.
Research printed in a leading medical journal demonstrates that while overweight individuals often shed a large proportion of their total mass while on the medication, the mass returns at an estimated rate of nearly a kilo each month upon discontinuation.
"Users using such drugs must be aware of the potential of rapid rebound weight gain when the medication is stopped," warns lead investigator Dr. Susan Jebb.
That rate of recovery suggests a return to original weight within about one and a half years.
Comparing Approaches
The analysis, which reviewed 37 of studies involving thousands of participants, compared the results of GLP-1 agonists with other pills.
Scientists emphasize that individuals who lose weight through diet and exercise typically experience a slower creep back—approximately 0.1 kg a month—once they finish.
Understanding the Fast Regain
Nutrition scientists believe the way of the injections accounts for the heightened weight return.
GLP-1 drugs imitate a body's own chemical called glucagon-like peptide-1, which controls appetite.
"Sustained high doses of GLP-1 levels several times higher than normal might result in the system to produce less of its endogenous GLP-1, and could lessen sensitivity to its actions," said Dr. Adam Collins, a nutrition researcher.
"Withdrawal of this medication results in hunger is no longer kept in check, making binge eating a significant risk."
A Chronic Disease?
Medical guidelines recommend the injections for people with weight-linked health risks, alongside prescribed diet and exercise modifications.
Many experts contend that, considering the significant potential of relapse, the treatment should be considered long-term.
This view is echoed by pharmaceutical companies, who say that the findings "highlight the persistent character of obesity," similar to managing diseases like high blood pressure.
Patient Experiences
People who have come off the jabs explain a sudden return of cravings.
"It was like a trigger activating and you're instantly ravenous," described a patient.
The struggle is worsened if individuals have not adopted lasting lifestyle or habit modifications during therapy.
Growing Use
Recent estimates indicate that a significant number of people in the UK have tried these injections in the past year, with desire continuing to grow.
- Use is more common among women compared to males.
- The middle-aged age group shows the highest level of interest.
- A large proportion obtain the medications through private prescriptions rather than public health services.
In conclusion, clinicians emphasize that while the jabs are powerful tools for shedding pounds, they are not a standalone cure and long-term success likely depends on ongoing lifestyle support.
