The McDougall Program, founded by Dr. John McDougall, is a starch-based, low-fat, whole-food, plant-based diet designed to help individuals regain their health, lose weight, and prevent chronic diseases. The program's philosophy is rooted in the belief that humans thrive on a diet of starches, supplemented with a variety of fruits and non-starchy vegetables, while avoiding animal products, oils, and processed foods. Understanding the specific food groups is crucial for success on this plan.
The Foundation: Starch-Based Eating
At the heart of the McDougall diet is the emphasis on eating starches as the primary source of calories. This may seem counterintuitive to those familiar with low-carb diet trends, but McDougall's research indicates that high-carb, low-fat starches provide sustained energy, promote satiety, and are rich in essential nutrients.
Why Starches?
- Complex Carbohydrates: Starches like potatoes, brown rice, and beans provide complex carbohydrates that break down slowly, offering a steady release of glucose to fuel the body and brain.
- Fiber-Rich: Whole starches are packed with dietary fiber, which aids digestion, supports a healthy gut microbiome, and helps create a feeling of fullness.
- Nutrient-Dense: Contrary to popular myth, whole starches are a powerhouse of vitamins, minerals, and antioxidants, especially when eaten with the skin.
Approved Food Categories
Following the McDougall program means prioritizing specific food groups that are central to the diet's success. These food categories form the bulk of all meals and snacks.
Starchy Foods (The Staples)
These are the foundational foods of the diet and can be eaten in abundance.
- Tubers: Potatoes (white, sweet, purple), yams, cassava.
- Grains: Brown rice, wild rice, oats, quinoa, barley, millet, corn (including whole corn tortillas).
- Legumes: Beans (black, kidney, pinto, garbanzo), lentils, split peas.
- Whole Grain Products: Whole-wheat pasta, whole-grain breads, buckwheat soba noodles (check ingredients for no oil).
Non-Starchy Vegetables (The Sides)
These add flavor, variety, and extra nutrients. They can be consumed freely.
- Leafy Greens: Spinach, kale, collard greens.
- Cruciferous Vegetables: Broccoli, cauliflower, Brussels sprouts.
- Colorful Vegetables: Bell peppers, carrots, tomatoes, zucchini, onions.
Fruits (The Sweetness)
Fruits provide natural sweetness, vitamins, and antioxidants. They are best enjoyed whole rather than as juice.
- Berries: Blueberries, strawberries, raspberries.
- Melons: Watermelon, cantaloupe.
- Citrus: Oranges, lemons, limes.
- Other Fruits: Apples, bananas, peaches.
Flavorings and Condiments
To enhance flavor without adding fat, a range of herbs, spices, and low-sodium condiments are approved.
- Herbs and Spices: Garlic powder, onion powder, cumin, chili powder, oregano, thyme, cinnamon.
- Condiments: Mustard, low-salt vegetable broth, salsa, vinegar, soy sauce (low sodium), hot sauce.
Foods to Avoid on the McDougall Plan
To maximize health benefits and avoid common pitfalls, several food groups are strictly excluded.
- Animal Products: This includes all meat (red meat, poultry), fish, eggs, and dairy products.
- All Added Oils: Regardless of the type (e.g., olive oil, coconut oil, avocado oil), all added fats are avoided. The program asserts that oils are liquid fats that contribute to obesity and chronic disease.
- Processed Foods: Most convenience foods, fast food, and highly processed items are not approved. The focus is on whole, recognizable ingredients.
- High-Fat Plant Foods: In stricter versions of the diet (like the Maximum Weight Loss program), high-fat plant foods such as nuts, seeds, and avocados are also avoided or severely limited. Tofu and other refined soy products are also limited.

Conclusion
The McDougall diet is a powerful and straightforward approach to nutrition based on decades of clinical experience and research. By focusing on a foundation of whole-food starches and incorporating a wide array of vegetables and fruits, individuals can achieve significant improvements in their health without relying on restrictive calorie counting or animal products. The core principle is simple: build your meals around whole, unprocessed plants and leave out the animal products and oils. For anyone interested in a clear-cut and effective path to better health, understanding what foods are approved by McDougall is the first and most crucial step.
