Summary

This study looks at how the body processes fructose, a type of sugar. Researchers want to see if the small intestine can turn fructose into glucose to protect the liver, and whether this process is weaker in people with obesity. The study will involve 40 healthy volunteers, some with a normal weight and some with obesity. No treatment is given; it is an observational study to better understand how the body handles sugar.
