I was looking into buying a box of zone bars as an inbetween meals snack.

BUT I noticed they are not 30-30-40. Can anyone explain to me why? Here's a link to the nutrition facts on a zone bar: http://www.zonediet.com/shop/produc...-bars.aspx

Thanks!

I'm pretty sure that 1 block= 3F, 9C, 7P. This is not going to be exactly on, though. There will almost always be a bit of rounding error. The link for the zone bars states the following: 8 Fat, 24 Carb, 5 Fiber, 16 Protein. You end up with: 8/3=2.67F, (24-5)/9=2.11C, 16/7=2.27P.....All of these are pretty close to 2 blocks of each.

Please, correct me if I am wrong on this :-)

Will, 40-30-30 is an approximation. The acceptable P/C range for the Zone is from .6 to 1 (refer to the info in the first Zone book, THE ZONE). The Dr Sears Zone Sweet and Salty Nut Crunch bar that I have in my hand at the moment has a P/C of .94.

1bof fat is 1.5 g
1b of carb is 9 g
lb of prot is 7


3b of f is 4.5g
3b of carb is 27g
3b of prot is 21g

Almost Heidy.

The 1.5 gram fat block is only half of the 3 grams of fat needed to balance one complete block of P, C and F. the other half(another 1.5 grams of fat) is in the low fat protein block. This is the reason you're supposed to double the number of fat blocks you add when you choose a fat free protein instead of a low fat protein (to provide the minimum amount of fat needed for balance).

Here’s how Dr. Sears explains fat blocks (taken from MASTERING THE ZONE, page 292 and 293).

“Why is a fat block only 1.5 grams?
Every block of low-fat protein contains approximately 1.5 grams of “hidden fat”. Therefore, by adding one extra fat block (which is defined as 1.5 grams of fat) for each block of low-fat protein, you are actually consuming 3 grams of fat or two blocks (one internal in the protein and one external) for each protein block. If you are using fat-free protein sources, such as isolated protein powders, then you should be adding two blocks of fat to achieve the same ratio. Obviously, if you are eating higher fat protein choices, you would not be adding any extra fat blocks to your meal. Remember that every time you add additional fat blocks to a meal, they should be composed primarily of monounsaturated fat.”

Some common fat free proteins eaten on the Zone diet are egg whites, protein powder, some deli-style meats, and some soy products.
