The Zone Diet is a popular eating plan that focuses on balancing macronutrients to achieve optimal health and weight loss. One of the key components of the Zone Diet is the concept of Zone Blocks, which helps individuals control their portion sizes and maintain a balanced diet.

What are Zone Blocks?

Zone Blocks are a measurement system used in the Zone Diet to determine portion sizes and balance macronutrients. Each Zone Block consists of a specific amount of protein, carbohydrates, and fat. The goal is to consume a certain number of Zone Blocks per meal to maintain a balanced diet and stabilize blood sugar levels.

For example, one Zone Block of protein is equivalent to 7 grams, one Zone Block of carbohydrates is equivalent to 9 grams, and one Zone Block of fat is equivalent to 1.5 grams. The number of Zone Blocks you need per meal depends on factors such as your weight, height, activity level, and goals.
