What is the Block

The right ratio among carbohydrates, proteins and fats

The Zone Diet is a diet where it is established that each meal must be composed by a right ratio among Carbohydrates, Proteins and Fats (also called Diet 40-30-30). To implement this ratio the Zone Diet introduces the concept of Block.
Each Block is composed by 1 mini-block of Proteins, 1 mini-block of Carbohydrates and 1 mini-block of Fats.

Let's take another step forward:

  • 1 mini-block of Carbohydrates contains 9 grams of Carbohydrates
  • 1 mini-block of Protein contains 7 grams of Protein
  • 1 mini-block of Fats contains 3 grams of Fats

Furthermore, we remind you that:
  • 1 gram of Carbohydrates develops 4Kcal
  • 1 gram of Protein develops 4Kcal
  • 1 gram of Fats develops 9Kcal

Therefore, each mini-block of Carbohydrate is equivalent to 9 grams of Carbohydrates, each gram of Carbohydrate develops 4Kcal, so each mini-block of Carbohydrate develops a total of 36Kcal (4 Kcal for each of the 9 grams of carbohydrates contained in a mini block of Carbohydrates).
Furthermore, each mini-block of Protein is equivalent to 7 grams of Proteins, each gram of Proteins develops 4Kcal, so each mini-block of Protein develops a total of 28Kcal (4 Kcal for each of the 7 grams of protein contained in a mini block of Proteins).
Finally, each mini-block of Fat is equivalent to 3 grams of Fats, each gram of Fats develops 9Kcal, so each mini-block of Fat develops a total of 27Kcal (9 Kcal for each of the 3 grams of fat contained in a mini-block of fats).

Summarizing in tabular form:
Mini-block Macro-nutrient grams
per Mini-block
KCal developed
per gram
Tot. Kcal % on the Meal
Carbohydrate 9 gr. 4 Kcal per gr. 36 Kcal 40%
Protein 7 gr. 4 Kcal per gr. 28 Kcal 30%
Fat 3 gr. 9 Kcal per gr. 27 Kcal 30%
Exactly the 40-30-30 of the Zone Diet.

An example to go in depth: the first column shows the detail of a block:
Meal Mini-block Protein Mini-block Carbohydrate Mini-block Fat
Chicken: 27gr. 0,9 0 0,1
Pasta: 12gr. 0,1 1 0
Oil: 3gr. 0 0 1
Meal Total Block 1 1 1,1
