Overview

The Ornish diet was developed by Dr. Dean Ornish, a well-known cardiologist and nutrition expert.

What Does the Ornish Diet Involve?

The Ornish diet focuses on plant-based, whole foods, with an emphasis on fruits, vegetables, whole grains, legumes, and nuts. The diet is low in fat, with less than 10% of daily calories coming from fat. This is achieved by limiting animal products, such as meat, dairy, and eggs, and avoiding added oils and processed foods. The Ornish diet also encourages physical activity and stress reduction through techniques such as yoga and meditation, which are key components of the program.

How Does It Compare to Other Diets for Weight Loss and Overall Health?

The Ornish diet has been shown to be effective for weight loss and improving overall health. It has been compared to other diets, such as the Mediterranean diet and the Atkins diet, and has been found to have similar weight loss and health benefits. However, the Ornish diet has the added benefit of being a heart-healthy diet, as it has been shown to reverse heart disease and improve other cardiac risk factors.

Key Components

Emphasis on Plant-Based Whole Foods

Physical Activity and Stress Management

In addition to diet, the Ornish program also emphasizes physical activity and stress management.
