Question

Quick question class, is fat or carbohydrate the preferred energy source for the body? is it situational?

Answer 1

Carbohydrates are the preferred source of energy for the body.

The body prefers use of carbohydrates as the source of fuel for biological activities. During bouts of high intensity exercise, carbohydrates are used as the preferred source of fuel for 2-3 minutes. Beyond that point, fats serve as the fuel source and start to provide energy for the exercise.

This means that carbohydrates are the primary choice of energy. Once the carbohydrate store is depleted, the body transitions to fats as the source of energy.
