This is because "in a fasted state" before your breakfast, you are more likely to be deprived of the primary energy source, sugar. This favorably puts your body's secondary energy source, fat to work, resulting in a greater fat burn.
By simply choosing the right time to exercise, you can tap into the hidden advantage in the human body system to burn extra fat and lean out faster.
It's also one of the very reason why morning workouts are so popular and effective.
