Fresh analysis reveals that people who stop using popular slimming jabs like Mounjaro or Wegovy may regain reduced body mass far faster than those who halt conventional lifestyle regimens.
Research printed in a major medical journal points out that while overweight individuals frequently drop about a fifth of their total mass while on the medication, the weight returns at an estimated rate of nearly a kilo each month after stopping.
"People using such medications should be cognizant of the potential of rapid rebound weight gain when the medication concludes," cautioned expert Dr. Susan Jebb.
Such speed of recovery implies a return to pre-treatment weight within about 18 months.
Weighing Approaches
The research, which looked at 37 of studies involving thousands of patients, contrasted the outcomes of GLP-1 agonists with other pills.
Scientists point out that people who lose weight through lifestyle changes alone typically have a more gradual weight regain—approximately 100 grams monthly—after stopping.
Explaining the Quick Rebound
Nutrition scientists propose the mechanism of the jabs explains the heightened weight return.
GLP-1 drugs imitate a natural hormone called GLP-1, which helps regulate hunger.
"Long-term administration of the hormone concentrations far above than normal might result in the system to generate a reduced amount of its endogenous GLP-1, and may also diminish responsiveness to its actions," explained Dr. Adam Collins, a dietetics researcher.
"Withdrawal of this GLP-1 'fix' means hunger is unsuppressed, making binge eating far more likely."
An Ongoing Issue?
Medical guidelines suggest the injections for people with weight-linked health risks, alongside prescribed diet and exercise modifications.
Many experts contend that, considering the significant potential of weight regain, the treatment should be considered life-long.
This perspective is echoed by pharmaceutical companies, who note that the results "underscore the chronic nature of excess weight," akin to managing conditions like high blood pressure.
Patient Experiences
Users who have come off the jabs explain a intense return of appetite.
"It was like a switch that goes on and I was suddenly starving," described an individual.
This challenge is worsened if users have not established permanent lifestyle or habit modifications during therapy.
Growing Adoption
Survey data show that millions of people in the UK have tried weight-loss jabs in the last 12 months, with interest remaining high.
- Use is greater among females compared to men.
- The 40s and 50s demographic shows the greatest usage rates.
- A large proportion obtain the drugs through private healthcare rather than the NHS.
In conclusion, clinicians emphasize that while these medications are potent agents for weight loss, they are not a permanent solution and lasting health benefits hinges on integrated behavioural management.
