Fresh analysis indicates that individuals who come off popular weight-loss injections like Mounjaro or Wegovy may regain lost weight far faster than those who halt traditional lifestyle plans.
Research printed in a major medical journal shows that while obese people can lose a large proportion of their total mass while using the jabs, the mass comes back at an estimated rate of 0.8 kg per month after stopping.
"Users buying such medications must be aware of the potential of rapid weight regain when the medication concludes," stated researcher Dr. Susan Jebb.
Such speed of recovery means a return to starting weight in about 18 months.
Weighing Therapies
The analysis, which reviewed dozens of trials involving over 9,000 of patients, contrasted the effects of the injectable medications with conventional dieting.
Researchers note that people who lose weight through lifestyle changes alone usually have a slower creep back—approximately 100 grams monthly—once they finish.
Understanding the Rapid Regain
Nutrition scientists propose the way of the jabs explains the accelerated weight return.
These medications imitate a body's own chemical called GLP-1, which helps regulate feelings of fullness.
"Long-term administration of GLP-1 levels far above than the body's typical production might result in the system to produce less of its own natural hormone, and may also diminish sensitivity to its actions," said Dr. Adam Collins, a nutrition researcher.
"Withdrawal of this medication results in appetite is no longer kept in check, making excessive eating a significant risk."
An Ongoing Condition?
The NHS recommend the jabs for individuals with obesity-related medical conditions, accompanied by recommended lifestyle changes.
Many experts say that, given the significant potential of weight regain, the therapy is often ongoing.
This perspective is supported by pharmaceutical companies, who say that the results "underscore the persistent nature of excess weight," comparing it to managing conditions like high blood pressure.
Patient Experiences
Users who have come off the jabs describe a powerful resurgence of appetite.
"It was like something activating and you become ravenous," described one woman.
The struggle is compounded if individuals have not established lasting lifestyle or habit changes during treatment.
Growing Adoption
Recent estimates show that a significant number of people in the UK have used weight-loss jabs in the last 12 months, with desire remaining high.
- Adoption is higher among females compared to males.
- The 40s and 50s demographic shows the highest level of interest.
- Many access the drugs through private prescriptions rather than public health services.
In conclusion, researchers emphasize that while GLP-1 drugs are effective agents for shedding pounds, they are not a standalone solution and maintained weight loss hinges on combined behavioural changes.
