According to the McDougall Program, many chronic diseases can be prevented or even reversed by following a low-fat, whole-foods, plant-based diet. For those wondering what can you eat on a McDougall diet, the answer is found in the simple, yet powerful world of starch-centric meals. This diet centers on whole, unrefined plant foods like starches, vegetables, and fruits, while strictly avoiding all animal products and added oils.

The Foundation: Starches

At the core of the McDougall diet, also known as the Starch Solution, are complex carbohydrates from starches. These foods provide sustained energy, are naturally low in calories per pound, and are high in fiber, helping you feel comfortably full and satisfied without counting calories.

Types of Starchy Foods

  • Legumes: A key component of the diet, these provide protein and fiber. Examples include lentils (brown, red, green), black beans, kidney beans, pinto beans, chickpeas, and split peas.
  • Whole Grains: These are encouraged for their fiber and nutrients. Opt for whole-grain pasta, whole-grain bread, brown rice, wild rice, oats, barley, quinoa, and millet.
  • Starchy Vegetables: The original and most satisfying starches. These include potatoes (white, red, sweet), yams, corn, green peas, and winter squash.

Vegetables for Volume and Nutrition

Non-starchy vegetables are another essential part of the McDougall diet and can be consumed in unlimited quantities to add bulk, nutrients, and color to your meals. They are extremely low in calorie density, making them perfect for weight management.

Examples of Non-Starchy Vegetables

  • Leafy Greens: Spinach, kale, collard greens, and lettuce.
  • Cruciferous Vegetables: Broccoli, cauliflower, Brussels sprouts, and cabbage.
  • Root Vegetables: Carrots, beets, and radishes.
  • Other Veggies: Tomatoes, cucumbers, onions, garlic, bell peppers, zucchini, and mushrooms.

Fruits for Flavor and Antioxidants

Fruits are an important source of vitamins, minerals, and antioxidants on the McDougall diet. They can be enjoyed for flavor, but are recommended in moderation (about 3 servings daily) because of their higher concentration of simple sugars, which can be easy to over-consume.

Types of Fruits to Include

  • Berries: Strawberries, blueberries, raspberries.
  • Tree Fruits: Apples, pears, peaches, bananas.
  • Citrus: Oranges, grapefruits, lemons.
  • Melons: Watermelon, cantaloupe.

Condiments and Flavorings

Since the diet prohibits added oils, flavorful condiments and spices are crucial to make meals enjoyable. These should be low in fat and used to enhance the natural taste of the whole foods.

Oil-Free Condiment and Flavoring Ideas

  • Vinegars: Balsamic, red wine, and apple cider vinegar.
  • Mustard: Dijon or whole grain.
  • Soy Sauce or Tamari.
  • Nutritional Yeast: For a cheesy flavor.
  • Spices and Herbs: Cumin, coriander, turmeric, smoked paprika, chili powder, and dried herbs like oregano and basil.
  • Salsas, hot sauces, and vegetable broths.

Foods to Strictly Avoid

The McDougall diet is defined as much by what you eat as by what you do not. A strict adherence to avoiding certain food categories is necessary for achieving the program's intended health benefits.

Restricted and Prohibited Foods

  • Animal Products: This includes all meat, poultry, fish, eggs, and dairy (milk, cheese, yogurt, butter).
  • Added Oils and Fats: All added oils are banned, including vegetable, olive, canola, and coconut oil. High-fat plant foods like nuts, seeds, and avocados are also limited or avoided, as even small amounts can hinder weight loss.
  • Processed Foods: This includes refined grains (white bread, pasta), sugary snacks, junk food, and anything with artificial ingredients or preservatives. The focus is on whole, unprocessed foods.

The McDougall Diet vs. a Standard American Diet

To highlight the differences, here is a comparison between the starch-based McDougall diet and the typical Standard American Diet (SAD).

Putting the Program into Practice: A Pantry List

To successfully follow the McDougall diet, a well-stocked pantry is essential. Focusing on simple, unrefined ingredients makes meal preparation straightforward and delicious.

McDougall-Approved Pantry Staples

  • Grains: Brown rice, quinoa, whole-wheat pasta, rolled oats.
  • Legumes: Canned or dried black beans, lentils, chickpeas, and pinto beans.
