A recent study suggests that individuals who discontinue blockbuster weight-loss injections like Wegovy and Mounjaro may regain lost weight much more quickly than those who end traditional diet and exercise plans.
Findings released in a leading medical journal demonstrates that while overweight individuals can lose substantial amounts of their body weight while undergoing treatment, the mass returns at an average rate of 0.8 kg per month after stopping.
"People purchasing such medications must be informed of the potential of rapid weight regain when the medication concludes," stated expert Dr. Susan Jebb.
This pace of recovery suggests a return to pre-treatment weight in about 18 months.
Comparing Approaches
The research, which examined dozens of studies involving over 9,000 of patients, contrasted the outcomes of GLP-1 agonists with older methods.
Scientists note that individuals who shed pounds through lifestyle changes alone generally see a more gradual weight regain—perhaps 0.1 kg a month—post-intervention.
The Reason for the Rapid Regain
Experts believe the way of the injections is key to understanding the accelerated rebound.
The injections mimic a natural hormone called glucagon-like peptide-1, which helps regulate feelings of fullness.
"Sustained high doses of GLP-1 concentrations far above than normal could lead to the body to generate a reduced amount of its endogenous GLP-1, and could reduce sensitivity to its effects," said Dr. Adam Collins, a dietetics specialist.
"Withdrawal of this medication leads to hunger is unsuppressed, making excessive eating a significant risk."
A Chronic Condition?
The NHS suggest the injections for individuals with obesity-related medical conditions, accompanied by prescribed diet and exercise modifications.
Many experts contend that, considering the high risk of relapse, the therapy should be considered long-term.
This view is echoed by pharmaceutical companies, who say that the findings "underscore the persistent character of obesity," comparing it to managing conditions like high blood pressure.
Patient Accounts
People who have discontinued the jabs describe a powerful resurgence of appetite.
"I experienced something activating and you're instantly ravenous," recalled an individual.
This difficulty is compounded if users have not established sustainable lifestyle or habit changes during therapy.
Widespread Adoption
Survey data suggest that a significant number of people in the UK have tried these injections in the last 12 months, with interest being substantial.
- Adoption is greater among women compared to men.
- The 40s and 50s age group shows the highest level of interest.
- Many obtain the medications through private prescriptions rather than public health services.
In conclusion, clinicians stress that while these medications are powerful tools for shedding pounds, they are not a magic cure and maintained weight loss likely depends on combined behavioural changes.
