Frequently Asked Questions

What is the Zone Diet?

The Zone Diet is an anti-inflammatory eating plan created by Dr. Barry Sears. It follows a 40-30-30 ratio (40% carbs, 30% protein, 30% fat) and uses a 'block' system to balance meals for optimal hormonal response.

How do Zone Diet blocks work?

Each block contains 7g protein, 9g carbs, and 1.5g fat (about 100 calories). You eat the same number of each block type per meal to maintain the 40-30-30 ratio. Most people need 11-16 blocks per day.

What foods are emphasized in the Zone Diet?

Focus on lean proteins, low-glycemic carbs (vegetables, fruits), and healthy fats (olive oil, nuts, avocado). Limit high-glycemic carbs, processed foods, and inflammatory fats to stay 'in the zone.'
