A: Good snacks to have after working out combine sources of carbohydrate and protein. Both are very important to refuel the muscle of depleted energy stores. Carbohydrates replete low glycogen stores, and protein helps with the repair and growth of muscle.These snacks should be consumed as soon as possible after a workout as this is the greatest time to provide necessary nutrients. Muscles can be thought of as sponges after exercise and will absorb glucose and amino acids from carbohydrates and protein very readily.
