Gather a dozen runners and ask them if they think it's healthy to run on an empty stomach and you're likely to find that the group split in half. While getting away from meals or snacks in the hours before running probably will not hurt you, the consensus among many health experts is that feeding your body with the right foods before your workout is the healthiest option.
Taking a snack before running is best
If you go for a run on an empty stomach, you may experience fatigue and cut the trot (which will only hurt your intention to burn calories). Although some people exercise on an empty stomach, with the intention of burning fat faster, this belief is not necessarily true. In an article published in "The New York Times," Dr. David Prince notes that exercise without eating forces your body to draw energy from its carbohydrate and protein stores before it uses fat. Instead of coping with this situation, it is best to consume a light snack rich in carbohydrates and protein about an hour before running. Examples of suitable snacks include a banana and peanut butter or yogurt and granola.
