Energy bars are a convenient way to take in calories while you are competing or training, usually running or bicycling. They are meant to provide a large amount of calories (mostly carbohydrates) to working muscles in as little volume as possible.

So it’s much easier to carry an energy bar with you than normal food, which is not as calorie-dense. It also goes down faster. That’s really what it’s about – convenience. When training, you’re not eating food for enjoyment; you’re eating food for fuel. It’s more of an inconvenience than anything.

Energy bars should not be used as meal substitutes during a normal meal. They are no substitute for a healthy, well-balanced diet. (See: Energy Bars Aren’t Meant to Be Real Food.)

So when I review energy bars, I’m usually looking for high calories, plenty of carbohydrates, and more. I still favor more natural energy bars (few artificial ingredients and minimal processing,) but what I look for in an energy bar is not what I look for in normal health food.

Here are my energy bar reviews:
