The basic concept is that every time you eat, it must be in the correct
ratio of Protein to Carbohydrate to Fats.  That ratio is simply:
Almost equal calories of each. (Slightly more from Carbohydrates than
from Protein and Fat) The maximum control of insulin occurs when the
gram ratio of Carbohydrates to Protein to Fat are 9:7:3.  Therefore, the
size of the portions will reflect this fact. Carbohydrates will make up
the largest portion of your meal (fruits and vegetables are EMPHASIZED
over pasta breads and grains),protein next and fat last.
For simplicity sake, they refer to this quantity as a BLOCK OF FOOD.
Based on your body weight, you have a certain number of blocks of food
to eat each day, which are distributed as evenly as possible among 3
meals and two snacks.

You can learn about it in the two zone books:
