If you are cutting, you should keep the fruit to a minimum. However, cutting should not be continual (as some people seem to think around here). If you are preparing for a show, or photo shoot, very small amounts of fruit can be incorporated into a cutting diet for the first part until you come to that wonderful last stretch of cutting where you probably want to take it out all together.
When you are not cutting and just maintaining, despite what some of the people on this board say, fruit is indeed a VERY important part of your diet and should not be neglected. Remember, our bodies have been eating fruit for about what now? 20,000, 100,000 years? 250,000 years? Whatever homo classification you use.
Our old buddy Spatts used to eat fruit on a regular basis, and she was a FOX! Also she could've probably kicked all our asses repeatedly!
