Share 'HOW MANY OTHERS DOING 811 ARE EXCLUDING OVERT FATS?'

I have decided to exclude overt fats from my 100 days training for 80/10/10 by the book.  To me this is a no brainer.  My body has a history of storing fat too easily and I'm finally getting my body fat % down.  I want it to be 22% by the end of the 100 day training.   How many others are doing the same?  Why?  Any problems/challenges?  Thanks for your input.
