How soon after I workout should I eat? And what should I eat? These are some questions that come up frequently with my clients. In short, we should eat as soon after the workout as possible... within 30 minutes, if possible. This meal should consist of both carbohydrate and protein. We need to replenish our protein stores as well as the carbohydrates in order to restore the depleted muscle glycogen. An example of a good post-workout meal would be a whey-protein drink with fruit and/or fruit juice. This type of protein will be digested by your body much faster than any solid food or other type of protein. Remember to stay away from fats after the workout because they will slow down the digestive process.
