To eat or not to eat, that is the question

I'm working on learning how to get maximum results out of my walks. As I've written before, I'm not having a good week energy wise. So, I'm going to try the following eating guidelines for the rest of the week and see if it makes a difference:

• Eat 2 to 4 hours before a workout.
• Eat 400 to 800 calories at your pre-exercise meal.
• Choose high-carb foods that are low in fat and have a moderate amount of protein.
• Drink at least 10 ounces of water or sports drink 2 hours before you exercise.

Wish me luck!
