Morning cardio is still controversial in academic circles, but as far as I'm concerned it's a closed case and the verdict is in: it works! But don't take my word for it - examine the facts, try it and decide for yourself. The argument in favor of fasted early morning cardio burning more fat goes something like this:

1. After an overnight 8-12 hour fast, your body's stores of glycogen are depleted and you burn more fat when glycogen is low.

2. Eating causes a release of insulin. Insulin interferes with the mobilization of body fat. Less insulin is present in the morning; so more body fat is burned when cardio is done in the morning.

3. There is less carbohydrate (glucose) in the bloodstream when you wake up after an overnight fast. With less glucose available, you burn more fat.

4. If you eat immediately before a workout, you have to burn off what you just ate first before tapping into stored body fat (and insulin is elevated after a meal.)

5. When you do cardio in the morning, your metabolism stays elevated for a period of time after the workout is over. If you do cardio in the evening, you burn calories during the session, but you fail to take advantage of the "afterburn" effect because your metabolic rate drops dramatically as soon as you go to sleep.
