Fresh analysis suggests that individuals who stop using popular weight-loss injections like Wegovy and Mounjaro may regain shed pounds at a significantly accelerated pace than those who end conventional diet and exercise programs.
Published data in a prominent medical journal shows that while overweight individuals often shed a large proportion of their total mass while using the jabs, the weight is regained at an estimated rate of 0.8 kg per month once they quit.
"People buying such medications must be cognizant of the risk of fast weight regain when the treatment is stopped," warns lead investigator Dr. Susan Jebb.
That rate of recovery implies a reversion to original weight in about one and a half years.
Analyzing Treatments
The analysis, which examined 37 of studies involving thousands of participants, contrasted the outcomes of GLP-1 agonists with other pills.
The team note that individuals who shed pounds through diet and exercise typically have a less rapid weight regain—around 0.1 kg a month—once they finish.
Explaining the Rapid Rebound
Nutrition scientists suggest the way of the injections accounts for the amplified regain.
The injections imitate a body's own chemical called GLP-1, which controls appetite.
"Sustained high doses of the hormone concentrations several times higher than the body's typical production may cause the body to produce less of its endogenous hormone, and could lessen sensitivity to its effects," explained Dr. Adam Collins, a dietetics researcher.
"Withdrawal of this medication leads to hunger is no longer kept in check, making excessive eating far more likely."
An Ongoing Issue?
The NHS advise the injections for people with obesity-related health risks, accompanied by recommended diet and exercise modifications.
Professionals say that, due to the high risk of weight regain, the therapy should be considered life-long.
This view is echoed by drug manufacturers, who say that the findings "highlight the long-term nature of obesity," comparing it to managing conditions like diabetes.
User Testimonies
People who have come off the medication report a intense resurgence of appetite.
"It was like a switch that goes on and I was suddenly extremely hungry," recalled a patient.
This challenge is exacerbated if users have not adopted lasting dietary or behavioural modifications during therapy.
Widespread Adoption
Figures indicate that a significant number of adults in the UK have used these injections in the last 12 months, with desire remaining high.
- Adoption is more common among females compared to men.
- The middle-aged demographic shows the greatest usage rates.
- A large proportion access the medications through private prescriptions rather than the NHS.
In conclusion, clinicians caution that while the jabs are effective tools for weight loss, they are not a magic cure and maintained weight loss hinges on combined behavioural support.
