Fresh analysis reveals that people who come off new slimming jabs like Wegovy and Mounjaro tend to recover shed pounds far faster than those who stop conventional diet and exercise plans.
Published data in a prominent medical journal shows that while obese individuals can lose substantial amounts of their body weight while using the jabs, the weight is regained at an average rate of 0.8 kg per month once they quit.
"People buying these treatments need to be aware of the risk of quick weight regain when the therapy is stopped," stated lead investigator Dr. Susan Jebb.
Such speed of recovery means a reversion to original mass in about 18 months.
Analyzing Approaches
The analysis, which looked at dozens of studies involving thousands of patients, compared the outcomes of these new drugs with other pills.
The team note that individuals who shed pounds through lifestyle changes alone generally have a less rapid creep back—around 100 grams monthly—once they finish.
Understanding the Fast Rebound
Nutrition scientists believe the mechanism of the drugs is key to understanding the heightened rebound.
The injections copy a natural hormone called GLP-1, which moderates feelings of fullness.
"Sustained high doses of GLP-1 levels far above than normal might result in the body to generate a reduced amount of its own natural hormone, and could reduce sensitivity to its actions," explained Dr. Adam Collins, a nutrition specialist.
"Withdrawal of this medication means hunger is unsuppressed, making binge eating much more probable."
An Ongoing Issue?
Health authorities recommend the jabs for individuals with obesity-related medical conditions, accompanied by prescribed lifestyle changes.
Professionals argue that, due to the likelihood of weight regain, the therapy is often life-long.
This perspective is reinforced by pharmaceutical companies, who note that the findings "emphasize the persistent nature of excess weight," akin to managing diseases like diabetes.
Patient Accounts
Individuals who have come off the medication report a sudden return of hunger.
"It felt as if a switch flipping and you become starving," recalled an individual.
This challenge is worsened if patients have not adopted lasting lifestyle or habit changes during treatment.
Growing Interest
Survey data suggest that a significant number of people in the UK have tried weight-loss jabs in the last 12 months, with interest remaining high.
- Use is greater among females than males.
- The middle-aged demographic shows the highest usage rates.
- Many access the medications through private healthcare rather than public health services.
Ultimately, clinicians emphasize that while GLP-1 drugs are effective agents for shedding pounds, they are not a permanent fix and long-term success likely depends on combined lifestyle changes.
