The Switch-Over Point for Fat Burning During Exercise
After approximately 90 minutes of moderate intensity exercise, those who have eaten within one to three hours of the workout will burn less fat than those who have fasted for three hours or more prior to exercise. High intensity workouts lasting no more than 60 seconds are more effective at burning fat than moderate intensity workouts after the 90 minute point.

Summary
Eating before moderate intensity exercise reduces the amount of fat burned after 90 minutes, while fasting before exercise increases the amount of fat burned. High-intensity training, such as sprints or weightlifting, is not affected by pre-exercise eating.
