Summary

This study looks at whether taking 200mg of caffeine (about two cups of coffee) changes how active your brown fat is when you are mildly cold. Brown fat is a type of body fat that burns energy to generate heat. Researchers will use PET-CT scans to measure brown fat activity in 12 healthy adults after they take caffeine or a placebo and then experience mild cold. The goal is to understand how caffeine might influence this process.
