The Ornish Diet is a heart-healthy eating plan created by Dr Dean Ornish, an American physician and researcher. It is designed to improve heart health by focusing on plant-based foods, regular exercise, stress management, and healthy lifestyle habits. Unlike many diets that only aim to help people lose weight, the Ornish Diet was developed to reduce the risk of heart disease and improve overall health.
Several studies, including a report published in the journal ‘Baylor University Medical Center Proceedings’ have shown that following the Ornish Diet, along with other healthy lifestyle changes, may help lower cholesterol levels, improve blood pressure, and support better heart health. While it may not be suitable for everyone, it has become one of the best-known eating plans for people who want to protect their heart.
What Is the Ornish Diet?
The Ornish Diet is a low-fat, mainly vegetarian eating plan. It encourages people to eat natural, whole foods while limiting foods that are high in unhealthy fats and added sugars. The diet is based on the belief that healthy food, regular physical activity, emotional wellness, and social support all work together to improve heart health, shares Dr Deebanshu Gupta, Cardiologist at Sarvodya Hospital, Jalandhar.

Benefits of the Ornish Diet for the Heart
