A recent study reveals that individuals who come off blockbuster weight-loss injections like Wegovy and Mounjaro can put back on lost weight far faster than those who halt traditional diet and exercise plans.
Research printed in a leading medical journal points out that while overweight people can lose a large proportion of their body weight while undergoing treatment, the mass comes back at an estimated rate of nearly a kilo each month after stopping.
"Users buying these medications should be aware of the potential of fast rebound weight gain when the medication is stopped," warns researcher Dr. Susan Jebb.
This pace of recovery suggests a reversion to original mass in about one and a half years.
Analyzing Therapies
The research, which looked at dozens of studies involving over 9,000 of patients, contrasted the outcomes of the injectable medications with older methods.
Researchers emphasize that people who lose weight through diet and exercise generally see a slower creep back—perhaps 100 grams monthly—post-intervention.
The Reason for the Fast Rebound
Doctors believe the mechanism of the drugs explains the amplified rebound.
GLP-1 drugs imitate a body's own chemical called GLP-1, which controls hunger.
"Long-term administration of GLP-1 concentrations several times higher than the body's typical production might result in the body to generate a reduced amount of its endogenous hormone, and may also lessen responsiveness to its actions," said Dr. Adam Collins, a dietetics researcher.
"Withdrawal of this GLP-1 'fix' leads to appetite is uncontrolled, making excessive eating far more likely."
A Chronic Disease?
Medical guidelines advise the jabs for people with obesity-related health risks, accompanied by prescribed lifestyle changes.
A number of clinicians contend that, given the high risk of weight regain, the treatment is often ongoing.
This view is supported by pharmaceutical companies, who note that the findings "emphasize the long-term character of obesity," similar to managing diseases like hypertension.
User Experiences
Individuals who have come off the medication describe a sudden return of hunger.
"I experienced something activating and you become ravenous," described a patient.
The struggle is worsened if users have not established lasting lifestyle or habit changes during treatment.
Growing Adoption
Figures indicate that millions of people in the UK have tried these injections in the last 12 months, with desire being substantial.
- Use is more common among women compared to males.
- The middle-aged age group shows the greatest level of interest.
- Many access the medications through private healthcare rather than the NHS.
Ultimately, researchers caution that while these medications are effective agents for shedding pounds, they are not a permanent solution and long-term success relies on integrated lifestyle support.
