New research indicates that individuals who come off blockbuster GLP-1 drugs like Wegovy and Mounjaro may regain shed pounds far faster than those who stop conventional diet and exercise programs.
Findings released in a leading health publication demonstrates that while overweight people frequently drop a large proportion of their body weight while on the medication, the weight returns at an estimated rate of nearly a kilo each month upon discontinuation.
"Users using such medications must be cognizant of the potential of rapid rebound weight gain when the medication is stopped," warns lead investigator Dr. Susan Jebb.
This pace of regain implies a return to pre-treatment weight within about 18 months.
Weighing Treatments
The analysis, which examined dozens of studies involving thousands of patients, contrasted the results of GLP-1 agonists with conventional dieting.
Scientists emphasize that individuals who shed pounds through dieting typically see a less rapid creep back—around 0.1 kg a month—once they finish.
Explaining the Quick Rebound
Nutrition scientists suggest the mechanism of the drugs is key to understanding the heightened rebound.
The injections copy a body's own chemical called GLP-1, which helps regulate feelings of fullness.
"Long-term administration of the hormone concentrations several times higher than the body's typical production may cause the system to produce less of its own natural hormone, and may also diminish responsiveness to its actions," said Dr. Adam Collins, a nutrition researcher.
"Discontinuation of this GLP-1 'fix' leads to hunger is unsuppressed, making binge eating a significant risk."
A Chronic Condition?
The NHS advise the jabs for people with weight-linked health risks, accompanied by recommended lifestyle changes.
Professionals say that, due to the significant potential of weight regain, the therapy might need to be life-long.
This opinion is reinforced by pharmaceutical companies, who note that the findings "highlight the persistent nature of excess weight," comparing it to managing conditions like diabetes.
User Testimonies
Users who have discontinued the jabs report a powerful return of hunger.
"It felt as if something that goes on and you become ravenous," recalled a patient.
This difficulty is compounded if individuals have not established permanent dietary or behavioural modifications during treatment.
Widespread Use
Survey data suggest that a significant number of adults in the UK have tried weight-loss jabs in the past year, with desire being substantial.
- Use is higher among women compared to men.
- The middle-aged age group shows the highest usage rates.
- A large proportion access the drugs through private healthcare rather than the NHS.
In conclusion, experts caution that while the jabs are potent agents for shedding pounds, they are not a magic cure and lasting health benefits relies on combined lifestyle changes.
