If you’re looking for an accelerated way to shed some extra body fat, try doing your aerobic training first thing in the morning on an empty stomach. As the theory goes, by morning, you’ve exhausted the majority of your glycogen stores since so many hours have passed since you’ve eaten. So if you workout on an empty stomach, your primary fuel source right out of the gate is your stored body fat.
For the record, there are some contradicting ideas floating around the fitness world about how or if this really works. But from a pure, in the trenches, experiential perspective, I’ve never seen this practice not work in a dramatic and quantifiable way. In fact, many competitive bodybuilders employ this tactic as an extra intense way to get shredded before a contest. So I say, try it for yourself and watch the excess fat melt away.
