In the Zone diet, one block consists of how many grams of carbohydrate, protein, and fat?

• A. 9 g fat, 7 g carbohydrate, 3 g protein
• B. 5 g carb, 10 g protein, 2 g fat
• C. 12 g carb, 6 g protein, 2 g fat
• D. 9 g carb, 7 g protein, 3 g fat

Answer: (D)

In the Zone diet, a block is a fixed mix of macronutrients you count rather than weighing every nutrient individually. A single block provides nine grams of carbohydrate, seven grams of protein, and three grams of fat. This consistent combination makes meal planning simpler and aims to stabilize insulin while promoting fullness by pairing carbs with protein and fat in each block. The other options would not match the standard block makeup used in this approach, which is why the nine/seven/three gram mix is the correct reference for one Zone block.
