Fresh analysis indicates that patients who come off blockbuster slimming jabs like Wegovy and Mounjaro tend to recover reduced body mass much more quickly than those who halt traditional lifestyle regimens.
Published data in a leading medical journal demonstrates that while obese people frequently drop about a fifth of their body weight while on the medication, the mass is regained at an average rate of 0.8 kg per month upon discontinuation.
"Users buying these treatments need to be informed of the potential of quick weight regain when the treatment is stopped," stated lead investigator Dr. Susan Jebb.
That rate of recovery means a return to original weight in about one and a half years.
Analyzing Therapies
The research, which looked at dozens of studies involving thousands of patients, contrasted the effects of the injectable medications with conventional dieting.
Scientists emphasize that individuals who lose weight through lifestyle changes alone generally have a less rapid creep back—approximately 0.1 kg a month—after stopping.
The Reason for the Rapid Rebound
Nutrition scientists propose the mechanism of the drugs explains the amplified rebound.
These medications copy a natural hormone called GLP-1, which controls appetite.
"Long-term administration of the hormone levels far above than normal may cause the system to generate a reduced amount of its endogenous GLP-1, and could lessen sensitivity to its effects," noted Dr. Adam Collins, a nutrition specialist.
"Stopping of this hormone supplement leads to hunger is unsuppressed, making excessive eating a significant risk."
A Lifelong Issue?
The NHS recommend the jabs for people with weight-linked medical conditions, alongside prescribed lifestyle changes.
A number of clinicians contend that, given the likelihood of relapse, the treatment is often ongoing.
This perspective is supported by drug manufacturers, who say that the findings "emphasize the long-term character of obesity," comparing it to managing diseases like high blood pressure.
Patient Experiences
People who have come off the medication explain a sudden resurgence of appetite.
"It was like something flipping and you're instantly starving," described one woman.
This difficulty is exacerbated if individuals have not developed sustainable lifestyle or habit modifications during therapy.
Significant Use
Recent estimates suggest that a significant number of people in the UK have used weight-loss jabs in the past year, with demand continuing to grow.
- Use is greater among females than men.
- The middle-aged demographic shows the greatest usage rates.
- Many access the medications through private prescriptions rather than public health services.
In conclusion, clinicians caution that while these medications are powerful agents for shedding pounds, they are not a standalone cure and long-term success relies on combined lifestyle support.
