What is the Zone diet?
The Zone diet is a nutrition plan focused on maintaining hormonal balance through the right ratio of protein, carbs and fat. Its main goal is to optimize health, increase energy and support weight control. In the Zone, every meal consists of 40% carbs, 30% protein and 30% fat.
What is a "block" and why does it matter in the Zone?
A block is the basic unit for measuring nutrients in the Zone. One block contains 7 grams of protein, 9 grams of carbs and 1.5 grams of fat. It helps you portion food precisely, so you maintain optimal hormonal balance. The number of blocks you need depends on your individual needs.
How do I calculate how many blocks I need per day?
The number of blocks you should eat daily depends on your age, gender, physical activity and body composition. Men typically need around 14-16 blocks a day, and women 11-13 blocks. For a more precise number, use ZoneIt's free Daily Blocks calculator, or consult a specialist.
