Fresh analysis indicates that patients who discontinue popular slimming jabs like Wegovy and Mounjaro may regain reduced body mass far faster than those who halt conventional diet and exercise regimens.
Published data in a prominent health publication demonstrates that while overweight people frequently drop substantial amounts of their body weight while on the medication, the mass comes back at an estimated rate of nearly a kilo each month after stopping.
"Individuals using such drugs must be cognizant of the risk of quick weight regain when the medication is stopped," warns lead investigator Dr. Susan Jebb.
Such speed of recovery means a reversion to starting mass within about a year and a half.
Weighing Treatments
The study, which looked at dozens of trials involving over 9,000 of patients, contrasted the outcomes of the injectable medications with conventional dieting.
Scientists emphasize that people who shed pounds through diet and exercise generally experience a less rapid creep back—perhaps 100 grams monthly—after stopping.
Understanding the Quick Regain
Experts believe the mode of action of the drugs explains the amplified rebound.
GLP-1 drugs imitate a body's own chemical called GLP-1, which moderates appetite.
"Long-term administration of GLP-1 levels several times higher than the body's typical production could lead to the system to generate a reduced amount of its own natural hormone, and may also reduce sensitivity to its actions," said Dr. Adam Collins, a nutrition expert.
"Discontinuation of this hormone supplement leads to hunger is uncontrolled, making overeating a significant risk."
An Ongoing Issue?
Health authorities recommend the jabs for people with obesity-related health risks, alongside prescribed diet and exercise modifications.
Professionals contend that, considering the high risk of weight regain, the therapy might need to be life-long.
This perspective is supported by pharmaceutical companies, who state that the results "highlight the long-term nature of excess weight," comparing it to managing conditions like high blood pressure.
User Experiences
Users who have come off the medication report a intense resurgence of cravings.
"It felt as if something flipping and I was suddenly starving," recalled one woman.
The struggle is worsened if individuals have not established lasting lifestyle or habit changes during therapy.
Widespread Use
Recent estimates suggest that millions of people in the UK have used weight-loss jabs in the past year, with desire continuing to grow.
- Use is higher among women compared to males.
- The 40s and 50s age group shows the highest usage rates.
- A large proportion obtain the drugs through private prescriptions rather than the NHS.
In conclusion, clinicians stress that while the jabs are effective tools for shedding pounds, they are not a permanent solution and maintained weight loss likely depends on combined behavioural support.
