Fresh analysis indicates that individuals who discontinue popular GLP-1 drugs like semaglutide or tirzepatide may regain shed pounds far faster than those who end conventional lifestyle plans.
Research printed in a leading medical journal points out that while overweight people can lose about a fifth of their total mass while using the jabs, the weight is regained at an average rate of nearly a kilo each month after stopping.
"Users using such medications need to be cognizant of the potential of quick rebound weight gain when the therapy is stopped," stated lead investigator Dr. Susan Jebb.
Such speed of regain implies a return to starting mass within about one and a half years.
Analyzing Therapies
The analysis, which looked at dozens of studies involving thousands of patients, contrasted the outcomes of these new drugs with older methods.
The team point out that people who shed pounds through dieting usually experience a less rapid creep back—approximately 100 grams monthly—post-intervention.
The Reason for the Fast Rebound
Experts suggest the way of the jabs accounts for the heightened weight return.
These medications mimic a natural hormone called glucagon-like peptide-1, which helps regulate hunger.
"Artificially providing GLP-1 concentrations several times higher than the body's typical production could lead to the system to produce less of its own natural hormone, and could reduce responsiveness to its actions," noted Dr. Adam Collins, a dietetics expert.
"Stopping of this GLP-1 'fix' means appetite is unsuppressed, making excessive eating a significant risk."
A Lifelong Disease?
Medical guidelines advise the injections for individuals with weight-linked medical conditions, accompanied by recommended diet and exercise modifications.
Professionals argue that, due to the significant potential of weight regain, the treatment might need to be long-term.
This view is echoed by drug manufacturers, who say that the results "emphasize the long-term nature of obesity," comparing it to managing diseases like high blood pressure.
User Experiences
Users who have stopped the medication report a powerful resurgence of appetite.
"It was like a trigger activating and you become ravenous," described an individual.
The struggle is exacerbated if individuals have not adopted lasting dietary or behavioural changes during treatment.
Growing Interest
Survey data indicate that millions of adults in the UK have used these injections in the last 12 months, with demand remaining high.
- Adoption is greater among females compared to males.
- The 40s and 50s age group shows the greatest usage rates.
- Many obtain the drugs through private prescriptions rather than public health services.
In conclusion, experts caution that while the jabs are effective tools for weight loss, they are not a magic fix and lasting health benefits likely depends on ongoing lifestyle changes.
