Fresh analysis indicates that patients who discontinue blockbuster weight-loss injections like semaglutide or tirzepatide can put back on reduced body mass at a significantly accelerated pace than those who halt traditional diet and exercise plans.
Published data in a leading medical journal shows that while overweight individuals can lose substantial amounts of their body weight while undergoing treatment, the mass is regained at an estimated rate of nearly a kilo each month once they quit.
"Individuals using these treatments must be aware of the danger of quick weight regain when the treatment is stopped," cautioned expert Dr. Susan Jebb.
Such speed of regain implies a return to original weight in about 18 months.
Comparing Treatments
The study, which looked at 37 of trials involving over 9,000 of patients, compared the outcomes of GLP-1 agonists with older methods.
Scientists point out that individuals who lose weight through diet and exercise generally experience a more gradual weight regain—perhaps 0.1 kg a month—post-intervention.
Explaining the Quick Regain
Nutrition scientists suggest the mode of action of the jabs is key to understanding the amplified rebound.
These medications imitate a body's own chemical called GLP-1, which moderates feelings of fullness.
"Sustained high doses of the hormone levels far above than the body's typical production might result in the system to generate a reduced amount of its endogenous GLP-1, and may also reduce responsiveness to its actions," noted Dr. Adam Collins, a dietetics expert.
"Discontinuation of this hormone supplement leads to appetite is unsuppressed, making binge eating far more likely."
A Chronic Issue?
Health authorities recommend the injections for individuals with obesity-related health risks, accompanied by prescribed diet and exercise modifications.
Professionals contend that, due to the significant potential of relapse, the therapy should be considered ongoing.
This perspective is echoed by drug manufacturers, who note that the results "highlight the persistent nature of excess weight," akin to managing conditions like hypertension.
User Experiences
Users who have come off the medication describe a sudden resurgence of appetite.
"It was like a trigger activating and you become starving," recalled a patient.
This challenge is worsened if individuals have not adopted permanent dietary or behavioural changes during treatment.
Growing Use
Figures indicate that a significant number of adults in the UK have used these injections in the last 12 months, with desire being substantial.
- Adoption is more common among females compared to males.
- The middle-aged demographic shows the greatest level of interest.
- A large proportion access the medications through private healthcare rather than public health services.
In conclusion, experts caution that while the jabs are powerful agents for shedding pounds, they are not a permanent solution and lasting health benefits hinges on combined lifestyle support.
