What Is The Ornish Diet All About
A diet famous for preventing heart disease by minimising the intake of fat, animal proteins, and refined carbs while maximizing the intake of unrefined plant-based food, is the Ornish diet. In this low-fat vegetarian dietary routine, you are encouraged to replace refined carbohydrates with complex ones, and at the same time consume fat in limited quantities while avoiding animal proteins and processed food. Along with nutrition, this diet goes further by incorporating regular exercise, stress management and a social support system into one’s lifestyle to achieve optimal health.
What Is The Ornish Diet
The Ornish diet is a unique dietary and lifestyle program founded by Dr. Dean Ornish, clinical professor of medicine at the University of California, San Francisco, and creator of the Preventive Medicine Research Institute, Sausalito. His motto is “feel better, live longer, lose weight and gain health”. The strategies used in the Ornish diet are effective for preventing
and even reversing heart disease, preventing chronic diseases, lowering blood pressure, managing weight, and promoting optimal health. Followers of the diet can cater the plan according to their goals, however someone who is trying to reverse heart disease will naturally require bigger changes in their lifestyle, hence their diet plan will be slightly stricter than the regular prevention diet plan.
Ornish divides food into five groups, where group one is most beneficial to health and group five least. So, eat ample amounts of fibrous vegetables and fruits
(group one), and low-fat dairy instead of full-fat (group four). Regarding exercise, emphasise on aerobic activities, flexibility and, resistance training. Manage stress
through meditation, deep breathing techniques and yoga. Figure out which combinations work best for you and make sure to practice daily. Ornish also stresses social support from people you love, affects one’s health positively. Clear up a bit of your schedule and spend some quality time with your friends and family.
The factor that makes this program unique among hundreds of diet plan, is its scientific root. Dr. Ornish backs his lifestyle program with hard-won science, his research and findings have been published in leading medical journals, for instance The Journal of the American Medical Association in 1983 & 1998, and The Lancet in 1990. They report an average improvement of over 300% to the heart and 2.5 times lesser cardiac events.

Ornish diet is undoubtedly wonderful for your heart, it has been proven that heart disease, beyond being stoppable, can also be reversed, without drugs or surgery, through changes in diet and lifestyle. Dr. Ornish and his colleagues examined the ability of 48 patients in 1998, to sustain intensive lifestyle changes for a total of five years and the effects of these lifestyle changes on coronary heart disease. Devotion to lifestyle changes, fluctuations in coronary artery percent diameter stenosis, and cardiac episodes were monitored. The results produced by the experimental group displayed substantial improvements compared to the control group, whose condition worsened.

Weight loss during the Ornish diet is gradual, the idea of rapid weight loss may seem attractive, but it actually results in unintended loss of lean body mass in turn slowing metabolism. The Ornish program’s approach to weight management is adopting a healthy lifestyle where the combination of a low-fat diet and exercise results in weight loss.
