Fresh analysis indicates that individuals who discontinue popular weight-loss injections like Wegovy and Mounjaro can put back on reduced body mass at a significantly accelerated pace than those who end traditional diet and exercise programs.
Published data in a major medical journal points out that while obese people can lose substantial amounts of their total mass while using the jabs, the weight is regained at an average rate of 0.8 kg per month after stopping.
"Users using such treatments need to be cognizant of the risk of quick rebound weight gain when the medication ends," stated researcher Dr. Susan Jebb.
Such speed of regain suggests a return to starting mass in about 18 months.
Analyzing Therapies
The analysis, which looked at dozens of studies involving thousands of patients, contrasted the results of the injectable medications with other pills.
The team emphasize that people who lose weight through diet and exercise generally experience a more gradual weight regain—around 100 grams monthly—after stopping.
Understanding the Rapid Regain
Doctors propose the way of the injections is key to understanding the heightened regain.
GLP-1 drugs imitate a body's own chemical called glucagon-like peptide-1, which moderates feelings of fullness.
"Sustained high doses of the hormone levels several times higher than the body's typical production could lead to the system to produce less of its endogenous hormone, and could reduce sensitivity to its effects," said Dr. Adam Collins, a nutrition specialist.
"Discontinuation of this hormone supplement results in appetite is no longer kept in check, making excessive eating much more probable."
An Ongoing Disease?
Medical guidelines suggest the jabs for people with obesity-related medical conditions, alongside prescribed lifestyle changes.
Many experts contend that, considering the high risk of weight regain, the therapy is often ongoing.
This view is reinforced by pharmaceutical companies, who state that the findings "underscore the persistent nature of excess weight," comparing it to managing diseases like hypertension.
Patient Accounts
People who have stopped the jabs report a sudden resurgence of appetite.
"I experienced a trigger that goes on and you become starving," recalled an individual.
This difficulty is compounded if individuals have not developed lasting lifestyle or habit modifications during therapy.
Significant Interest
Survey data suggest that millions of people in the UK have used weight-loss jabs in the past year, with desire remaining high.
- Use is higher among females than men.
- The 40s and 50s demographic shows the greatest level of interest.
- A large proportion access the medications through private prescriptions rather than public health services.
Ultimately, researchers stress that while the jabs are powerful agents for weight loss, they are not a standalone solution and lasting health benefits likely depends on integrated behavioural support.
