New research indicates that people who stop using popular weight-loss injections like Wegovy and Mounjaro may regain reduced body mass at a significantly accelerated pace than those who halt conventional lifestyle regimens.
Published data in a prominent health publication demonstrates that while obese individuals can lose substantial amounts of their body weight while using the jabs, the mass returns at an average rate of 0.8 kg per month once they quit.
"People purchasing such treatments should be informed of the risk of fast rebound weight gain when the treatment ends," cautioned lead investigator Dr. Susan Jebb.
Such speed of regain suggests a return to pre-treatment weight in about 18 months.
Weighing Treatments
The study, which reviewed dozens of studies involving thousands of patients, contrasted the outcomes of the injectable medications with older methods.
Scientists note that people who shed pounds through diet and exercise generally see a more gradual weight regain—approximately 100 grams monthly—once they finish.
Understanding the Quick Rebound
Experts propose the way of the injections accounts for the amplified rebound.
GLP-1 drugs mimic a body's own chemical called GLP-1, which controls hunger.
"Sustained high doses of GLP-1 concentrations far above than normal might result in the system to generate a reduced amount of its own natural GLP-1, and could lessen sensitivity to its effects," explained Dr. Adam Collins, a nutrition specialist.
"Stopping of this hormone supplement leads to appetite is uncontrolled, making overeating far more likely."
An Ongoing Issue?
Health authorities recommend the jabs for individuals with weight-linked health risks, alongside recommended diet and exercise modifications.
Professionals argue that, due to the likelihood of relapse, the treatment is often ongoing.
This view is reinforced by drug manufacturers, who say that the results "underscore the persistent character of obesity," similar to managing conditions like diabetes.
Patient Testimonies
Users who have stopped the medication explain a powerful return of hunger.
"It was like a switch that goes on and I was suddenly starving," described a patient.
This challenge is exacerbated if individuals have not established sustainable lifestyle or habit modifications during treatment.
Significant Adoption
Recent estimates show that millions of people in the UK have tried these injections in the last 12 months, with interest remaining high.
- Use is greater among women compared to men.
- The 40s and 50s demographic shows the greatest usage rates.
- A large proportion access the medications through private healthcare rather than the NHS.
Finally, experts stress that while these medications are effective agents for weight loss, they are not a magic cure and maintained weight loss hinges on ongoing lifestyle support.
