Eating before exercise?

This is to answer a question in one of the comments. Should you eat before or after exercise?

When To Eat: Exercising on a full stomach is not ideal. Food that remains in your stomach during an event may cause stomach upset, nausea, and cramping. To make sure you have enough energy, yet reduce stomach discomfort, you should allow a meal to fully digest before the start of the event. This generally takes 1 to 4 hours, depending upon what and how much you've eaten. Everyone is a bit different, and you should experiment prior to workouts to determine what works best for you.

If you have an early morning race or workout, it's best to get up early enough to eat your pre-exercise meal. If not, you should try to eat or drink something easily digestible about 20 to 30 minutes before the event. The closer you are to the time of your event, the less you should eat. You can have a liquid meal closer to your event than a solid meal because your stomach digests liquids faster.

What To Eat: Because glucose is the preferred energy source for most exercise, a pre-exercise meal should include foods that are high in carbohydrates and easy to digest. This include foods such as pasta, fruits, breads, energy bars and drinks. Also see: Energy for Exercise - Fat or Carbs?.

Suggested Pre-Exercise Foods: Eating before exercise is something only the athlete can determine based upon experience, but some general guidelines include eating a solid meal 4 hours before exercise, a snack or a high carbohydrate energy drink 2 to 3 hours before exercise, and fluid replacement (sports drink) 1 hour before exercise.
