What I eat is a subset of the McDougall Program way of eating. That Program is the best therapeutic way of eating for some individuals who are ill—for example, with obesity:
Nutritionist Jeff Novick lists diet programs similar in their overall pattern: http://www.jeffnovick.com/RD/Articles/Entries/2013/12/5_The_Specturm_Of_Health__The_Evidence_For_A_Whole_Food_Plant_Base_Diet_-_Pt_1.html
Occasionally friends ask what diet I recommend for maintaining or enhancing health for a lifetime. The way of eating that I generally recommend is not what I eat. The diet I recommend is the one I learned forty years ago, at the age of 30, from the book, Live Longer Now: The First One Hundred Years of Your Life, by Nathan Pritikin and others. A few used, inexpensive paperback copies of the book are available: http://www.amazon.com/Live-Longer-Now-Prit/dp/0425086917
At age 30, I had clogged arteries around my heart, chest pains (especially when I was under physical or mental stress), pain on the inside of my left arm (under stress), and high blood pressure. I had been eating the Standard American Diet—high fat, high protein, and Calorie Rich and Processed foods (C.R.A.P.). By adopting the Pritikin diet, described below, I lost 75 pounds in 15 months and got rid of all my symptoms.
4. No added, isolated fat. This means no butter, margarine, olive oil, bacon grease, and so forth. Learn to boil, bake, and steam foods, not fry them. The fats we need are contained in the foods we eat. We do not need to add isolated fats.
PROPORTIONS. I suggest roughly these proportions:
60% starches—intact or whole. Examples are potatoes, yams, and rice.
25% vegetables—intact or whole. Examples are spinach and bell peppers.
10% fruit—intact or whole. Examples are blueberries and oranges.
5% meats high in B12 and maybe D—in very small quantities, such as 1 tablespoon per meal. Examples are clams, oysters, chicken liver, beef liver, and red salmon.
EXCLUSIONS. Avoid all dairy products (though Pritikin allowed them in small quantities if very low fat). Avoid all C.R.A.P. foods such as candy and ice cream. Exclude alcohol, coffee, and tobacco. You may want to exclude wheat and soy, two foods that cause trouble for some individuals. Last, minimize salt. (Because I have a tendency to high blood pressure, my current, one-year experiment is to eliminate all salt. So far, my blood pressure is lower.)
RESULTS. On the Pritikin Program, all my heart disease symptoms disappeared and I lost about one pound per week, on average, for 75 weeks—without trying to lose weight and without restricting the amount that I ate. Of course, most of the weight loss occurred at the start. I only wanted to be healthy. I succeeded. I am nearing 70.
LOSING TOO MUCH? If you lose too much weight following the four steps above, add processed foods such as whole-grain pancakes and noodles, as well as small amounts of high-fat foods (whole or intact) such as nuts, avocados, olives, and so forth.
P. S. — Nutritionist Jeff Novick, for whom I have a lot of respect, discusses the spectrum of generally healthy diets, including those that include small amounts of animal products.
