Fresh analysis reveals that patients who stop using new slimming jabs like Wegovy and Mounjaro tend to recover reduced body mass much more quickly than those who stop traditional lifestyle regimens.
Published data in a major medical journal demonstrates that while obese people can lose substantial amounts of their total mass while using the jabs, the weight returns at an average rate of 0.8 kg per month once they quit.
"People buying such treatments need to be aware of the risk of fast weight regain when the medication concludes," warns researcher Dr. Susan Jebb.
That rate of regain suggests a return to pre-treatment weight within about one and a half years.
Comparing Therapies
The research, which looked at dozens of studies involving thousands of patients, contrasted the results of the injectable medications with older methods.
Scientists point out that individuals who lose weight through lifestyle changes alone usually experience a more gradual creep back—perhaps 0.1 kg a month—after stopping.
Explaining the Quick Regain
Experts believe the mechanism of the drugs is key to understanding the heightened regain.
These medications copy a natural hormone called glucagon-like peptide-1, which moderates appetite.
"Long-term administration of GLP-1 concentrations far above than normal may cause the body to generate a reduced amount of its own natural hormone, and could reduce sensitivity to its actions," explained Dr. Adam Collins, a dietetics researcher.
"Stopping of this hormone supplement results in hunger is uncontrolled, making excessive eating a significant risk."
A Lifelong Disease?
Health authorities suggest the jabs for people with obesity-related health risks, alongside recommended lifestyle changes.
Many experts argue that, given the significant potential of weight regain, the treatment is often ongoing.
This view is reinforced by pharmaceutical companies, who note that the findings "emphasize the persistent nature of obesity," comparing it to managing conditions like diabetes.
Patient Testimonies
People who have come off the jabs describe a intense return of cravings.
"It was like a trigger activating and I was suddenly ravenous," recalled a patient.
The struggle is worsened if patients have not established permanent lifestyle or habit changes during treatment.
Growing Interest
Survey data indicate that a significant number of adults in the UK have used these injections in the last 12 months, with demand continuing to grow.
- Use is higher among females compared to men.
- The middle-aged demographic shows the highest level of interest.
- A large proportion access the drugs through private prescriptions rather than the NHS.
Ultimately, experts caution that while the jabs are effective agents for shedding pounds, they are not a magic fix and lasting health benefits hinges on combined lifestyle management.
