After-effects of Exercise

It turns out that after you walk, or ride a bike or treadmill,  the exercise causes your body to burn calories as a higher rate for the rest of the day. So a good time to work out is first thing in the morning. Here are some reasons a pre-meal workout gets rid of fat better:

1. When you wake up in the morning after an overnight 8-12 hour fast, your body’s stores of glycogen are somewhat depleted. Doing cardio in this state causes your body to mobilize more fat because of the unavailability of glycogen.
2. Eating causes a release of insulin. Insulin interferes with the mobilization of body fat. Less insulin is present in the morning; therefore, more body fat is burned when cardio is done in the morning.
3. There is less carbohydrate (glucose) “floating around” in the bloodstream when you wake up after an overnight fast. With less glucose available, you will 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 so you definitely benefit from it, but you fail to take advantage of the “afterburn” effect because your metabolic rate drops dramatically as soon as you go to sleep.

So work out before breakfast.
