A recent study indicates that individuals who stop using blockbuster weight-loss injections like Wegovy and Mounjaro may regain lost weight at a significantly accelerated pace than those who end traditional lifestyle plans.
Findings released in a leading health publication demonstrates that while obese people can lose about a fifth of their total mass while on the medication, the weight is regained at an estimated rate of nearly a kilo each month once they quit.
"Individuals buying these medications need to be aware of the potential of rapid weight regain when the medication concludes," warns lead investigator Dr. Susan Jebb.
That rate of recovery suggests a return to pre-treatment weight within about a year and a half.
Analyzing Approaches
The research, which looked at 37 of trials involving thousands of participants, compared the results of the injectable medications with other pills.
Scientists note that people who shed pounds through lifestyle changes alone typically experience a more gradual creep back—perhaps 100 grams monthly—after stopping.
Explaining the Quick Rebound
Experts believe the mechanism of the jabs explains the heightened regain.
These medications copy a natural hormone called glucagon-like peptide-1, which controls appetite.
"Artificially providing the hormone levels far above than the body's typical production may cause the system to produce less of its own natural GLP-1, and could lessen sensitivity to its effects," explained Dr. Adam Collins, a nutrition expert.
"Stopping of this hormone supplement leads to appetite is uncontrolled, making overeating much more probable."
An Ongoing Condition?
Health authorities recommend the jabs for people with weight-linked health risks, alongside recommended diet and exercise modifications.
Many experts argue that, given the significant potential of weight regain, the treatment should be considered long-term.
This view is reinforced by pharmaceutical companies, who note that the results "underscore the chronic character of obesity," comparing it to managing diseases like high blood pressure.
Patient Experiences
Individuals who have come off the jabs report a sudden resurgence of hunger.
"I experienced a switch activating and you become starving," recalled a patient.
This challenge is exacerbated if users have not established sustainable lifestyle or habit changes during treatment.
Significant Interest
Recent estimates indicate that a significant number of people in the UK have used weight-loss jabs in the past year, with desire being substantial.
- Adoption is greater among women compared to men.
- 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 these medications are potent tools for weight loss, they are not a permanent solution and long-term success relies on combined behavioural support.
