Answer: It really is dependent upon your goal. If you are a recreational exerciser or simply working out for fitness, weight loss, etc., then the timing of pre- and post-workout feedings is not crucial. But doing so can make the workout more productive. For competitive athletes, the practice of consuming the proper snack 10-45 minutes before a workout has become standard protocol in order to maximize energy levels for the training/event period. As for post-workout, the prevailing wisdom used to dictate taking in a carbohydrate-rich meal within 90 minutes after a workout to increase recovery and glycogen resynthesis. However, recent research has shown that immediate pre- and post-workout feeding, preferably in a quickly delivered liquid form, can increase muscle gains significantly over the older standard practice of getting it within 90 minutes. This post-workout meal should be higher in carbs and sugars, with about 12-20 grams of protein and minimal fat. A normal, carbohydrate rich meal can be eaten one-and-a-half to two hours later.
