how long should i eat before i workout?
How much to eat depends on the frequency, intensity, and duration of your workout, among other factors. If you have an hour or less before your workout, a general guideline is to have about 1 gram of carbohydrate for every kilogram of your body weight (divide pounds by 2.2 to determine weight in kilograms). Some fuel is better than no fuel at all. Even if you only ate a banana, its carbs -- 30 grams -- will help.
