Fresh analysis suggests that patients who stop using new weight-loss injections like Wegovy and Mounjaro can put back on lost weight much more quickly than those who end traditional lifestyle programs.
Published data in a leading health publication shows that while obese individuals often shed substantial amounts of their body weight while on the medication, the mass returns at an average rate of nearly a kilo each month once they quit.
"Individuals using these medications should be informed of the risk of quick weight regain when the therapy ends," warns lead investigator Dr. Susan Jebb.
Such speed of recovery suggests a return to pre-treatment mass in about one and a half years.
Weighing Approaches
The analysis, which reviewed 37 of trials involving thousands of patients, contrasted the outcomes of these new drugs with conventional dieting.
The team emphasize that individuals who lose weight through lifestyle changes alone typically have a slower creep back—approximately 100 grams monthly—after stopping.
Understanding the Fast Rebound
Experts believe the way of the jabs accounts for the accelerated weight return.
The injections copy a natural hormone called glucagon-like peptide-1, which moderates hunger.
"Sustained high doses of GLP-1 concentrations several times higher than the body's typical production might result in the system to produce less of its own natural GLP-1, and may also lessen sensitivity to its actions," noted Dr. Adam Collins, a dietetics researcher.
"Discontinuation of this hormone supplement leads to hunger is uncontrolled, making overeating a significant risk."
A Lifelong Disease?
Medical guidelines suggest the jabs for individuals with weight-linked medical conditions, accompanied by prescribed diet and exercise modifications.
Many experts argue that, given the high risk of relapse, the treatment is often ongoing.
This view is reinforced by drug manufacturers, who state that the results "emphasize the chronic character of excess weight," similar to managing conditions like high blood pressure.
Patient Experiences
Individuals who have stopped the jabs report a intense return of cravings.
"It felt as if something activating and you become ravenous," described one woman.
This challenge is compounded if users have not developed lasting lifestyle or habit modifications during treatment.
Significant Adoption
Survey data indicate that millions of people in the UK have used these injections in the past year, with desire being substantial.
- Adoption is more common among females compared to males.
- The 40s and 50s age group shows the highest usage rates.
- A large proportion obtain the drugs through private prescriptions rather than public health services.
Ultimately, experts stress that while these medications are powerful agents for shedding pounds, they are not a magic fix and lasting health benefits likely depends on combined behavioural changes.
