How many grams in a fat block?
Technically speaking, each fat block is 3 grams. In his writings, Dr. Sears has assumed one would be using a Low-fat protein source (not non-fat), such as chicken, for their protein requirement. In each block of low-fat protein, there is approx. 1.5 grams of “hidden” fat. Therefore, you only need to add 1.5 grams of fat to get the desired 3 grams. If you are using a NON-fat protein source, such as non-fat cottage cheese or protein powder, you should double your fat blocks from the amounts as they are listed in the books in order to get the full 3 grams of fat per block. Making this adjustment will yield the 30%P, 40%C, and 30%F Zone ratio depending on which type of protein you are using. Likewise, if you are using a protein source which is higher in fat, you shouldn’t add any additional fat.
