My daugthers nutritionist sent her home with a few pages of info. regarding the zone diet. It really interested me, but I was confused because it mentioned 10g. of fat per block, and then in another area it mentioned 1.5g per block. Has the zone been revised, and am I reading mixed info. It stated 7g.protein, 9g.carbs. but not sure correct amount of fat. Would love to find the correct amount of fat to use per block. Thanks, Olga

7 grams of Protein = 1 Zone Block (1 Zone serving)
9 grams of NET Carbs = 1 Zone Block (1 Zone serving)
Net Carbs = Total carbs minus Fiber
1.5 grams of Fat = 1 Zone Block (or 1/2 of a Zone serving)
BECAUSE, you need 3 grams of Fat (a full Zone serving) for each Block of Protein/Carbs.
WHY: Because most Low-Fat Protein has some Fat in it.
SO, Dr. Sears says you need to add an additional 1.5 grams of fat for each 7 grams of Protein.
UNLESS your protein is Fat FREE! Then you add a full serving of Fat at 3 grams.
.
YES, it would have been much easier (and more consistent) for everyone if Dr. Sears just stated that 3 grams of Fat = 1 Zone Block (1 Zone serving) which it does, and it would have been consistent with Protein and Carbs, but he did not, so it requires this detailed explanation.

Thanks John, appreciate the clarification.
