2.Choose an energy bar that’s high in carbohydrates
Since you eat an energy bar to get energy, it better be high in carbohydrates as that’s the body’s preferred source of energy. High means anything over 25 grams of carbohydrates for an average size energy bar weighing 30-50 grams.
Its fat content is also important as fat slows down energy intake and puts a strain on your stomach. Anything up to 1 gram max of fat per average size bar is acceptable. The lower the fat, the better.
