New research reveals that people who discontinue popular weight-loss injections like Wegovy and Mounjaro tend to recover lost weight far faster than those who halt conventional lifestyle plans.
Published data in a leading medical journal shows that while overweight individuals can lose a large proportion of their total mass while on the medication, the weight returns at an average rate of nearly a kilo each month after stopping.
"Individuals using these treatments must be cognizant of the potential of quick weight regain when the therapy ends," stated lead investigator Dr. Susan Jebb.
Such speed of regain implies a reversion to original weight in about 18 months.
Comparing Approaches
The analysis, which examined 37 of studies involving over 9,000 of participants, compared the results of the injectable medications with older methods.
Scientists emphasize that individuals who lose weight through diet and exercise generally experience a more gradual creep back—around 100 grams monthly—post-intervention.
Explaining the Fast Rebound
Doctors propose the mode of action of the injections explains the accelerated regain.
GLP-1 drugs copy a natural hormone called GLP-1, which moderates feelings of fullness.
"Sustained high doses of the hormone levels far above than the body's typical production might result in the body to generate a reduced amount of its own natural hormone, and could diminish responsiveness to its actions," noted Dr. Adam Collins, a dietetics expert.
"Withdrawal of this medication leads to hunger is uncontrolled, making overeating much more probable."
A Chronic Disease?
The NHS recommend the injections for people with weight-linked medical conditions, accompanied by prescribed lifestyle changes.
A number of clinicians say that, considering the high risk of relapse, the therapy should be considered ongoing.
This opinion is reinforced by drug manufacturers, who say that the findings "underscore the persistent nature of obesity," comparing it to managing conditions like diabetes.
User Testimonies
Users who have come off the medication explain a sudden resurgence of appetite.
"It felt as if something activating and I was suddenly starving," recalled an individual.
The struggle is compounded if individuals have not established lasting lifestyle or habit changes during treatment.
Widespread Adoption
Survey data suggest that a significant number of people in the UK have tried these injections in the last 12 months, with demand being substantial.
- Adoption is greater among women compared to males.
- The 40s and 50s age group shows the highest usage rates.
- A large proportion access the medications through private prescriptions rather than the NHS.
In conclusion, experts stress that while the jabs are potent tools for shedding pounds, they are not a standalone solution and maintained weight loss likely depends on integrated lifestyle changes.
