Who invented The Zone Diet?

• A. Dr Sears
• B. Dr Atkins
• C. Dr Ornish
• D. Dr Pritikin

Answer: (A)

The Zone Diet was created by Dr. Barry Sears. It centers on balancing meals to keep insulin and inflammatory responses stable, aiming for roughly 40% of calories from carbohydrates, 30% from protein, and 30% from fat at each meal. This hormonal balance is what the approach promotes to maintain steady energy and appetite control, hence the idea of staying “in the zone.” Other well-known approaches differ in focus—Atkins emphasizes very low carbs, Ornish emphasizes very low fat with plant-based foods, and Pritikin emphasizes low fat and high fiber—so Dr. Sears is the inventor associated with The Zone Diet.
