Heres the deal, and maybe someone can clarify it for me. I have the book "Mastering The Zone." I also have the book "What to eat in the Zone." Both written by Dr. Barry Sears. On page 24 of Mastering the Zone, it says and I quote "A fat block is only 1.5 grams of fat." In the book, What to eat in the Zone on page 19 it says, and I quote "a Zone fat block contains 3 grams of fat." Can you see why I'm confused?? One book says 1.5 grams of fat is 1 fat block, and the other says 3 grams of fat is a block. Which is correct, and moreso, its contradicting. I really need to know which is correct, because I require 4 blocks of fat at each meal(breakfast, lunch, dinner), except for snacks which I only require 1 block (mainly because of my high activity levels), and i need to know if i should have 6 grams of fat or 12 grams of fat at each meal...can someone clarify this for me???
Any response is greatly appreciated.

I just answered your other post, so just jump over there for the answer.

But, I am confused, now. Are you on a 3 block meal plan, or 4 blocks?

The books are both correct. 3 grams of fat is needed for each fully balanced block of P, C and F. Because the recommended Zone low fat protein sources contain half of that amount (1.5 grams of fat), the added fat blocks are designed to contain the other half (another 1.5 grams of fat). Together, the fat in the protein source and the added fat block equal the 3 grams of fat needed for balance (1.5 g + 1.5 g = 3 g).

for you requirement, you'd add 4 blocks of fat, each one containing 1.5 grams of fat, for a total of 6 grams added fat. This together with the 4.5 grams occurring in you low fat protein source will give you a total of 10.5 grams of fat in the meal. I've gone into detail here to address your question, but it is not necessary to get this detailed when you put meals together. Simply 4 blocks to each meal, and if you choose a fat free protein source add another 3 blocks (1.5 g each) to make up for the fat missing in the fat free protein. It's most important to have the minimum amount needed. A little extra dietary fat will enhance your ability to stay in the Zone and will not prevent the loss of excess stored body fat.

Either way, active lifestyles can benefit from extra fat blocks. If it feels good roll with it. If you feel drained of energy, add some fat. Find your zone.
