Fresh analysis suggests that individuals who discontinue blockbuster weight-loss injections like Wegovy and Mounjaro may regain reduced body mass much more quickly than those who halt conventional diet and exercise regimens.
Research printed in a major medical journal shows 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.
"People buying such medications should be cognizant of the danger of fast weight regain when the treatment is stopped," cautioned lead investigator Dr. Susan Jebb.
Such speed of regain implies a reversion to original mass in about one and a half years.
Comparing Treatments
The study, which examined dozens of studies involving thousands of participants, contrasted the outcomes of GLP-1 agonists with older methods.
The team note that people who lose weight through diet and exercise usually experience a less rapid creep back—approximately 100 grams monthly—post-intervention.
The Reason for the Rapid Rebound
Nutrition scientists believe the way of the injections is key to understanding the heightened regain.
These medications copy a natural hormone called GLP-1, which controls appetite.
"Artificially providing the hormone levels several times higher than the body's typical production could lead to the system to generate a reduced amount of its own natural GLP-1, and could diminish sensitivity to its effects," noted Dr. Adam Collins, a dietetics researcher.
"Stopping of this medication leads to appetite is unsuppressed, making overeating far more likely."
A Chronic Condition?
Medical guidelines advise the injections for people with obesity-related health risks, alongside prescribed diet and exercise modifications.
Professionals contend that, due to the significant potential of weight regain, the treatment should be considered ongoing.
This opinion is reinforced by pharmaceutical companies, who state that the findings "underscore the long-term character of obesity," akin to managing conditions like high blood pressure.
User Accounts
Individuals who have stopped the jabs describe a intense return of hunger.
"It was like a switch activating and I was suddenly extremely hungry," recalled an individual.
This difficulty is compounded if users have not adopted lasting lifestyle or habit changes during treatment.
Widespread Adoption
Survey data indicate that millions of people in the UK have used weight-loss jabs in the last 12 months, with demand being substantial.
- Use is higher among women compared to males.
- The 40s and 50s demographic shows the greatest level of interest.
- A large proportion access the medications through private healthcare rather than public health services.
In conclusion, experts emphasize that while the jabs are potent agents for weight loss, they are not a permanent solution and long-term success hinges on ongoing behavioural management.
