Eat something before you exercise in the morning

Its always better to have some carbohydrate food in the morning before going in for exercise. The reason being that you always need some sugar in order to burn fat. As they say " Fat is burned in the flame of carbohydrate ". If sugar is too low, the body doesn't burn fat, rather it converts to protein burning. This is seen in marathon runners during the last five or six miles of their 26-mile race. They've used up their glycogen stores and their bodies start burning amino acids (protein). So if you happen to have low glycogen in the morning, you're more likely to burn valuable protein, which comes primarily from the breakdown of muscle tissue.

For this reason, it's a good idea to drink a little orange juice to elevate blood sugar before you exercise first thing in the morning.
