Fresh analysis reveals that people who stop using blockbuster GLP-1 drugs like Wegovy and Mounjaro may regain reduced body mass much more quickly than those who stop conventional diet and exercise regimens.
Research printed in a leading health publication shows that while overweight individuals often shed substantial amounts of their total mass while undergoing treatment, the mass comes back at an average rate of nearly a kilo each month after stopping.
"Users buying these medications should be aware of the potential of fast weight regain when the therapy is stopped," warns expert Dr. Susan Jebb.
That rate of recovery suggests a return to original mass within about a year and a half.
Analyzing Approaches
The research, which looked at dozens of trials involving thousands of participants, compared the results of the injectable medications with conventional dieting.
The team point out that people who shed pounds through diet and exercise usually see a less rapid weight regain—perhaps 100 grams monthly—after stopping.
Understanding the Fast Regain
Doctors propose the mechanism of the jabs explains the accelerated regain.
GLP-1 drugs mimic a body's own chemical called GLP-1, which moderates feelings of fullness.
"Long-term administration of GLP-1 concentrations far above than normal might result in the system to produce less of its endogenous GLP-1, and could diminish responsiveness to its actions," said Dr. Adam Collins, a nutrition specialist.
"Stopping of this hormone supplement means hunger is unsuppressed, making binge eating a significant risk."
A Lifelong Condition?
Medical guidelines advise the jabs for people with obesity-related medical conditions, accompanied by prescribed diet and exercise modifications.
Professionals contend that, considering the high risk of weight regain, the treatment might need to be life-long.
This opinion is reinforced by drug manufacturers, who note that the results "emphasize the chronic character of obesity," akin to managing diseases like high blood pressure.
User Testimonies
Users who have discontinued the medication explain a sudden resurgence of cravings.
"It felt as if a trigger that goes on and you're instantly extremely hungry," said one woman.
The struggle is worsened if users have not developed permanent dietary or behavioural changes during treatment.
Growing Adoption
Recent estimates indicate that millions of adults in the UK have used weight-loss jabs in the past year, with desire continuing to grow.
- Adoption is higher among women compared to males.
- The middle-aged demographic shows the highest level of interest.
- A large proportion access the medications through private prescriptions rather than public health services.
Ultimately, clinicians stress that while the jabs are powerful agents for weight loss, they are not a magic fix and lasting health benefits hinges on combined lifestyle management.
