I think it is a good idea to have a nutritious and easily digestible snack an hour or 2 before a workout.  I don't like to workout on an empty stomach but, at the same time, I don't want to feel full while exercising.  So I usually just have a piece of fruit, a low-fat yogurt, or something along those lines.  Afterward, it is a completely different story.  You need to replenish your energy so carbs are a must after a workout, preferably whole grains so something like brown rice or whole grain pasta is great.  These carbs are filling and good for you, plus they replenish the energy you lose when you workout.  Also, exercise wears down your muscle tissue.  In order to increase muscle recovery, it is a good idea to have a solid punch of protein.  Foods like eggs (without too much yolk) and fish are also good.  I think any meal that has the above foods will make you feel full after a workout.

Thank you for those thoughts, I appreciate it very much.

For after a work-out: I was told to have protein so i have eaten whole wheat crackers (Blue Menu by presidents choice, they are healthier) with all natural organic peanut butter, some fruit like apples or raspberries, and of course water. I don't usually eat right before a work out, and if i do it's usually lunch and then i wait about 45 minutes before i go, to let the food digest. Hope this helps! Enjoy:)
