After my diagnosis of NHL in the early 90s, the chemo treatment that followed, and my recovery from the treatment about eight weeks following its end, I became very interested in physical fitness and went through a weight-training phase. During the course of that phase, I banished the car from the garage, parked the camper in the backyard, and replaced them with barbells, dumbbells, a rack for the plates, and even a used "universal" weight lifting machine that a friend of mine gave me, just to get it out of his garage. Of course I read a lot of books, and one author was Bill Pearl. Still on my bookshelf are his Keys to the Inner Universe and Getting Stronger.
During the present Crossfit era, with its emphasis on high intensity training and developing "the core," Body Building, Bill's sport, may seem a little quaint. But to Bill and many others it remains a completely serious pursuit. Diet was extremely important. Bill's approach to diet was (and is - he's still in business) very enlightened. Here are some excerpts from his discussion on diet in Keys to the Inner Universe, pages 33-35:
The high protein myth is so permanently engraved in our thinking that I
hesitate to suggest it may be erroneous. Yet due to my desire to help
the sincere seeker of lasting health and physical power, I am compelled
to try.
It is not difficult to understand how the high protein myth originated.
Proteins are important components of our daily nutrition. Your body is
built largely of proteins. Your muscles, hair, skin, vital organs, and
glands, even your hormones are made up of proteins. Twenty percent or
more of the cellular composition in your body is protein. Since your
body is constantly renewing and repairing itself, you need lots of
protein in your diet for the building of new cells.
And that leads us to the question, "Just how much is 'lots'?" Many
experts suggest that you need from seventy to two hundred and fifty
grams or more of protein each day. Scientists around the world are
beginning to suspect a mistake in their original estimation of our
protein needs. More and more evidence is turning up to show that enough
protein is good, but to much is bad. Sugar is essential for our
health, but too much sugar in the diet has been established as a cause
for many health disorders. We certainly need fats, but too much fat in
the diet will cause a legion of troubles. Even too much of certain
vitamins or minerals may cause ill health. And so it is also with
proteins, especially cooked animal proteins, which may cause disorders
in the metabolism and a biochemical imbalance in the tissues. These
conditions may lead to the most common degenerative diseases, including
arthritis, arteriosclerosis, and heart disease
Studies by well-known nutritional authorities show that our actual
requirement for protein is somewhere between thirty and forty grams per
day. One of the most reliable sources on matters of nutrition today is
The International Society for Research on Nutrition and Vital
Substances, the scientific council which is comprised of four hundred
doctors of medicine, bio-chemistry, nutrition, and natural science.
This foremost scientific authority has stated that our "classical"
protein requirement tables need an overhaul. "Meat, fish, and eggs
supplement a basic diet, but a daily intake of these foods is not
necessary," says The International Society for Research on Nutrition and
Vital Substances.
The outdated calculations with regard to human protein needs were based
on nineteenth century research by Justin Von Liebig, Karl von Voit, and
Max Lubner, who believed that man's daily protein requirement was one
hundred twenty grams. Until today, many of the beliefs and opinions
regarding protein requirements were based on these men's faulty
calculations. As Dr. H. B. Lewis had pointed out, it is, indeed, "very
dangerous when great men make mistakes." Although the official tables
of protein requirements have been showing lower listings for the past
several decades, and are now set at about one-half gram per pound of body
weight per day, many authorities continue to cling to the old,
outdated, "more, more, and more protein" idea, with a heavy emphasis on
animal proteins, mainly from red meats.
In accord with the latest research, and taking into consideration the
great variation of protein need of each individual, plus the extra
demands under conditions of stress, a general conclusion would be that
fifty to sixty grams of protein per day - with seventy-five to eighty
percent derived from vegetable sources - is sufficient for optimum
health. Proteins in excess of those amount are not needed by the body
and are only burned as fuel for energy, or stored as fat. As fuel,
proteins are inferior to natural carbohydrates and fats.
You do not need meat for protein. . . . The long held belief that meat proteins are superior to vegetable proteins has been disproven . . . You do also do not necessarily need meat protein for strength. . . .
The only thing Bill seemed to miss is the problem with dairy and eggs.

interesting that some of this applies to CrossFit, but then they have the whole almost 180-degrees different Paleo thing...
I don't get the paleo, Sean.
