The days that I feed like that I will eat a 4 - 6 oz portion every meal which ends up being 5 to 6 times per day. Lets look at the numbers.
6 x 4 ozs = 24 oz so that is a 1.5 lbs at 6 oz portions it comes out to 36 oz or 2.25 lbs. To get to calories it is 2.25 lbs X 453.59 grams per pound = 1020.58 grams X 4 calories per gram for protein = 4082.31 calories.
I think that is correct but I might have made a mistake as I am pretty fried at work today.
What we think, or what we know, or what we believe, is in the end, of little consequence. The only thing of consequence is what we do. -John Ruskin
