Fresh analysis suggests that people who discontinue popular weight-loss injections like Wegovy and Mounjaro tend to recover shed pounds far faster than those who end conventional lifestyle plans.
Findings released in a major medical journal points out that while overweight people often shed about a fifth of their body weight while on the medication, the mass is regained at an estimated rate of nearly a kilo each month after stopping.
"Individuals using such medications should be informed of the danger of rapid rebound weight gain when the treatment ends," cautioned lead investigator Dr. Susan Jebb.
That rate of recovery suggests a reversion to original mass within about 18 months.
Analyzing Approaches
The study, which looked at 37 of studies involving thousands of participants, contrasted the results of these new drugs with older methods.
Researchers note that individuals who shed pounds through lifestyle changes alone generally experience a more gradual creep back—perhaps 100 grams monthly—post-intervention.
The Reason for the Quick Rebound
Nutrition scientists suggest the mechanism of the drugs is key to understanding the heightened regain.
The injections mimic a natural hormone called glucagon-like peptide-1, which helps regulate hunger.
"Long-term administration of GLP-1 concentrations several times higher than normal could lead to the system to produce less of its own natural GLP-1, and could diminish sensitivity to its actions," noted Dr. Adam Collins, a dietetics researcher.
"Withdrawal of this hormone supplement means appetite is unsuppressed, making excessive eating a significant risk."
A Chronic Disease?
Health authorities advise the jabs for individuals with obesity-related medical conditions, alongside recommended lifestyle changes.
A number of clinicians contend that, considering the likelihood of weight regain, the treatment is often long-term.
This view is reinforced by drug manufacturers, who note that the findings "highlight the persistent character of excess weight," akin to managing diseases like high blood pressure.
User Experiences
Individuals who have discontinued the medication report a intense return of appetite.
"It was like a switch that goes on and I was suddenly starving," described an individual.
This difficulty is compounded if patients have not adopted lasting lifestyle or habit modifications during therapy.
Growing Use
Figures show that millions of adults in the UK have used these injections in the last 12 months, with desire being substantial.
- Use is higher among women compared to men.
- The middle-aged demographic shows the highest usage rates.
- A large proportion obtain the medications through private prescriptions rather than public health services.
In conclusion, researchers emphasize that while GLP-1 drugs are powerful agents for weight loss, they are not a permanent solution and maintained weight loss hinges on ongoing lifestyle support.
