From Chronic Diseases to Weight Loss: The Ornish Diet's Transformative Power

byRoxaine December 01, 2023

The Ornish diet, established in 1977 by Dr. Dean Ornish, a clinical professor of medicine at the University of California, San Francisco, and founder of the nonprofit Preventive Medicine Institute in Sausalito, California, is a low-fat eating approach. Its focus is on promoting the reversal of chronic diseases and overall improvement in health.

This dietary plan encourages the consumption of a diverse range of plant-based foods, including fruits, vegetables, whole grains, and legumes, according to Sarah Schlichter, a registered dietitian based in Frederick, Maryland. While the Ornish diet excludes meat, fish, or poultry, it does allow for limited intake of nonfat dairy products and eggs, adopting a lacto-ovo vegetarian approach.

The Ornish diet classifies food into five groups, ranging from the most healthful (group one) to the least healthful (group five). Notably, it constitutes one of the four fundamental components of the Ornish Lifestyle Medicine by Sharecare program pillars. The other pillars encompass stress management, fitness, and the belief in the importance of social connections, joy, and love for overall well-being and health, along with social support.

How Does It Work?

Caloric Restriction for Weight Loss (Optional): Calorie restriction is not mandatory unless weight loss is a specific goal.

Focus on Whole Foods: For non-weight loss purposes, the diet encourages the consumption of unprocessed fruits, vegetables, whole grains, legumes, soy products, nonfat dairy, and eggs in their natural forms.

Limited Refined Carbohydrates and Processed Foods: While small amounts of refined carbohydrates, processed foods, and added sugars are allowed, the emphasis is on avoiding these in favor of unprocessed alternatives.

Stress Management: Stress management techniques are recommended to handle daily stressors effectively.

Healthy Fat Consumption: Aim for a daily intake of 4 grams of healthy fats from sources like fish oil, flaxseed oil, nuts, seeds, and plankton-based omega-3 fatty acids. Fats should constitute 10% of daily calorie intake.

Switch to Low-Fat or Nonfat Dairy: Replace full-fat dairy products with low-fat or nonfat alternatives.

Incorporate Stress-Reduction Techniques: Integrate stress-reduction practices, such as meditation, into your morning routine.

Customizable Goals: While renowned for reversing heart disease, the Ornish diet is flexible enough for followers to tailor it to specific objectives, including weight loss, blood pressure reduction, or cancer prevention.

Overall, the Ornish diet underscores the importance of consuming healthy, plant-based, and whole foods, limiting animal products and processed foods, incorporating regular exercise, and adopting stress-reduction strategies for a holistic approach to health.

Can I Lose Weight on the Ornish Diet?

Yes, you can potentially lose weight on the Ornish Diet, and various studies suggest its effectiveness for weight loss. Here are some key points related to weight loss on the Ornish Diet:

Plant-Based Effectiveness: Studies indicate that a plant-based eating plan, such as the Ornish diet, can be successful for weight loss and chronic disease prevention.

Short-Term Weight Loss: In a study involving over 1,000 participants following the Ornish plan for a year, the average body mass index (BMI) decreased by almost 8%. This resulted in a shift from the "obese" category to the "overweight" category.

Fat Calorie Reduction and Weight Loss: A small but controlled study found that reducing fat calories led to a 67% greater weight loss among adults with obesity compared to reducing the same number of calories from carbohydrates, aligning with the Ornish plan's recommendations.

Long-Term Weight Loss Debate: Some experts argue that long-term weight loss might not be directly linked to lower fat intake. The prevailing view is that the overall calorie intake, regardless of whether they come from fat, carbs, or protein, plays a crucial role in sustained weight loss.

Caloric Intake Trumps Composition: A study involving over 800 overweight adults demonstrated no significant difference in weight loss between participants who derived 20% of their calories from fat and those who obtained 40% of their calories from fat.

While the Ornish Diet may contribute to weight loss, the overall caloric intake remains a critical factor for sustained results, and individual responses may vary.

Weight Maintenance and Management

The Ornish Diet is not only effective for weight loss but can also assist in weight maintenance. In a follow-up study to Ornish's heart disease-reversal trial, participants who had initially lost an average of 24 pounds after one year on the diet maintained a weight loss of 13 pounds from their original weight after five years.

Cost of the Ornish Diet

As the Ornish Diet is not a commercial diet, there are no membership fees, subscription costs, or required product purchases associated with following the diet. However, Ornish offers an intensive nine-week cardiac rehab program that includes guidance on nutrition and stress management. The typical cost for this program ranges from $7,000 to about $10,000.

It's worth noting that many health insurance companies may reimburse patients with cardiac disease for the cost of the Ornish program. Some insurers may also cover the diet and lifestyle program for Type 2 diabetes or individuals with two or more risk factors for chronic disease.

Medicare covers the Ornish program as part of its coverage for intensive cardiac rehab programs, extending to 18 four-hour sessions (twice weekly over nine weeks) aimed at reversing heart disease. Additionally, virtual participation has been covered since May 2020, thanks to a rule from the Department of Health and Human Services in response to the COVID-19 pandemic.

Costs Related to the Ornish Diet

Books and Cookbooks: You may incur costs if you choose to purchase books authored or co-authored by Dr. Dean Ornish about the diet. Additionally, there are Ornish diet cookbooks available for purchase online, along with essential guides like "The Spectrum" and "UnDo It," which are offered in paperback, hardcover, audio, and e-book formats.

Grocery Expenses: The basics of the Ornish diet include fruits, vegetables, whole grains, legumes, nuts, seeds, and egg whites. While the initial purchase of these items may seem expensive, it's worth considering potential savings by reducing spending on meat and processed foods. Over time, the health benefits may contribute to long-term cost savings on healthcare.

Long-Term Health Savings: According to experts, it's advisable to look at the long-term cost savings on healthcare that can result from adopting a healthful diet like the Ornish diet. Despite potentially higher upfront costs for food compared to a standard Western diet, the overall health benefits may lead to significant savings over the years.

In summary, while there may be some costs associated with books, cookbooks, and grocery expenses, the focus is on the potential long-term health and financial benefits of following a healthful diet like the Ornish diet.

Doing the Ornish Diet on a Budget

If you're following the Ornish Diet on a budget, consider these cost-saving tips for your grocery shopping:

Seasonal Fruits and Vegetables: Opt for fruits and vegetables that are in season as they tend to be more affordable and readily available.

Bulk Purchases for Non-Perishables: Buy non-perishable items like whole grains and brown rice in bulk to take advantage of lower unit prices.

Canned Vegetables and Fruits: Choose canned vegetables without additional sodium and canned fruits without added sugar, which can be cost-effective and have a longer shelf life.

Local Farmers Markets: Explore local farmers markets, as they often offer fresh produce at lower prices compared to regular grocery stores.

Meal Preparation: If time allows, prepare a few days' worth of meals in advance. This not only helps you save money but also ensures that you have nutritious options readily available, reducing the temptation to spend on convenience foods.

By incorporating these strategies into your shopping routine, you can align with the principles of the Ornish Diet while managing your budget effectively.

Program Customization: The diet's flexibility allows for customization based on individual health goals. While the program can be more restrictive for those aiming to reverse heart disease, Dr. Ornish suggests that the long-term benefits in terms of improved quality of life make it a worthwhile commitment.

Challenges with Fat Restriction: Research indicates that adhering to a plan that restricts fat intake to 10% of daily calories can be challenging for many individuals.

Considerations for Health Goals: For those whose health does not depend on strict adherence (e.g., individuals without heart disease), a more moderate approach with slightly higher fat intake or the Spectrum approach may be more sustainable.

While the Ornish Diet may have some challenges, its ease of following can be influenced by personal health goals, commitment levels, and the chosen approach within the Ornish program. Making more moderate changes that align with one's lifestyle is supported by Dr. Ornish before potentially making more significant adjustments as the benefits become evident.
