You should be eating at least 5 times a day!

Increase the number of meals consumed per day - On average, you should be eating some form of protein and vegetable combination that's low in fat and high in fiber every 2 -3 hours of the day. Doing so will give you an almost unfair advantage over those who only eat the normal 3 meals (or less) each day.

I recommend five meals a day, breakfast, snack, lunch, snack, dinner.  Also, make sure you are drinking plenty of water and avoiding diet sodas.

To your health!
