New research reveals that individuals who discontinue blockbuster GLP-1 drugs like Mounjaro or Wegovy may regain lost weight at a significantly accelerated pace than those who halt traditional diet and exercise regimens.
Findings released in a major health publication demonstrates that while overweight people can lose about a fifth of their body weight while on the medication, the mass returns at an estimated rate of 0.8 kg per month upon discontinuation.
"Individuals buying these treatments need to be informed of the danger of fast weight regain when the treatment concludes," warns expert Dr. Susan Jebb.
This pace of recovery implies a return to starting mass in about 18 months.
Comparing Approaches
The study, which reviewed 37 of studies involving thousands of patients, contrasted the results of the injectable medications with other pills.
The team point out that people who lose weight through lifestyle changes alone typically experience a more gradual creep back—perhaps 0.1 kg a month—post-intervention.
Understanding the Quick Regain
Doctors propose the mode of action of the drugs is key to understanding the heightened weight return.
The injections imitate a natural hormone called GLP-1, which controls appetite.
"Sustained high doses of GLP-1 concentrations several times higher than the body's typical production might result in the body to generate a reduced amount of its own natural GLP-1, and could diminish responsiveness to its effects," explained Dr. Adam Collins, a dietetics specialist.
"Discontinuation of this hormone supplement means hunger is unsuppressed, making overeating far more likely."
A Chronic Condition?
Medical guidelines suggest the injections for individuals with obesity-related health risks, alongside prescribed lifestyle changes.
Professionals say that, due to the significant potential of weight regain, the therapy is often life-long.
This opinion is supported by pharmaceutical companies, who state that the results "highlight the chronic nature of excess weight," comparing it to managing diseases like high blood pressure.
User Testimonies
Users who have come off the medication describe a powerful return of cravings.
"It was like something activating and you're instantly extremely hungry," recalled an individual.
This difficulty is exacerbated if users have not established lasting lifestyle or habit changes during therapy.
Widespread Use
Survey data indicate that millions of adults in the UK have tried weight-loss jabs in the past year, with interest remaining high.
- Use is more common among females compared to men.
- The middle-aged demographic shows the greatest usage rates.
- Many access the medications through private healthcare rather than public health services.
In conclusion, researchers stress that while GLP-1 drugs are potent tools for shedding pounds, they are not a magic solution and maintained weight loss relies on ongoing lifestyle support.
