Question 1

What is the Zone Diet and what is a "block"?

Accepted Answer

The Zone Diet is a 40/30/30 macro split: 40% carbs, 30% protein, 30% fat. A "block" is a unit of measurement: 1 protein block = 7g protein, 1 carb block = 9g carbs, 1 fat block = 1.5g fat. Adults typically eat 11–14 blocks/day split across 5 mini-meals (3 meals + 2 snacks).

Question 2

Who developed the Zone Diet and what is it based on?

Accepted Answer

Dr. Barry Sears developed it in his 1995 book "The Zone." It's based on the hypothesis that the 40/30/30 ratio controls eicosanoid hormones (prostaglandins, thromboxanes) that regulate inflammation, energy, and appetite. The eicosanoid theory has limited scientific consensus.

Question 3

Is the Zone Diet effective for weight loss and performance?

Accepted Answer

Studies show modest weight loss benefits similar to other structured diets. The protein content (30%) increases satiety and preserves lean mass. CrossFit adopted Zone as its official nutrition approach for athletes. It's particularly useful for those who prefer structured food portioning over calorie counting.

Question 4

How do I calculate my Zone blocks per day?

Accepted Answer

Estimate your lean body mass. Multiply by your activity factor (sedentary: 0.5, light: 0.6, moderate: 0.7, active: 0.8, very active: 0.9) to get daily protein grams. Divide by 7 to get protein blocks. Match carb and fat blocks in a 1:1:1 ratio per meal.
