New research indicates that patients who stop using blockbuster slimming jabs like Wegovy and Mounjaro may regain shed pounds far faster than those who halt conventional diet and exercise regimens.
Research printed in a major health publication demonstrates that while obese people frequently drop substantial amounts of their total mass while on the medication, the mass is regained at an estimated rate of 0.8 kg per month after stopping.
"People purchasing such medications should be informed of the risk of quick weight regain when the treatment concludes," warns researcher Dr. Susan Jebb.
Such speed of recovery suggests a reversion to original mass within about a year and a half.
Weighing Treatments
The study, which looked at 37 of trials involving over 9,000 of patients, contrasted the outcomes of these new drugs with other pills.
Researchers emphasize that people who lose weight through dieting usually see a more gradual creep back—around 0.1 kg a month—after stopping.
Understanding the Rapid Regain
Nutrition scientists propose the mode of action of the drugs explains the accelerated weight return.
GLP-1 drugs imitate a body's own chemical called glucagon-like peptide-1, which helps regulate hunger.
"Long-term administration of GLP-1 concentrations several times higher than the body's typical production might result in the system to produce less of its endogenous hormone, and could lessen sensitivity to its effects," said Dr. Adam Collins, a dietetics researcher.
"Stopping of this hormone supplement leads to hunger is unsuppressed, making binge eating a significant risk."
A Lifelong Disease?
Health authorities recommend the jabs for people with weight-linked medical conditions, accompanied by prescribed diet and exercise modifications.
Professionals argue that, due to the high risk of weight regain, the therapy should be considered ongoing.
This perspective is supported by pharmaceutical companies, who state that the findings "highlight the chronic nature of obesity," akin to managing conditions like hypertension.
Patient Testimonies
Individuals who have stopped the medication explain a intense return of appetite.
"It felt as if something that goes on and you become ravenous," described a patient.
This difficulty is exacerbated if individuals have not developed sustainable lifestyle or habit changes during therapy.
Significant Interest
Figures indicate that millions of people in the UK have used weight-loss jabs in the past year, with interest being substantial.
- Adoption is greater among females compared to males.
- The middle-aged age group shows the greatest level of interest.
- A large proportion obtain the drugs through private prescriptions rather than public health services.
Finally, clinicians caution that while the jabs are potent agents for weight loss, they are not a magic cure and maintained weight loss relies on ongoing behavioural support.
