To start, Kast’s statement about evolution being for producing more DNA (children) rather than long life is VERY insightful, and may touch on the answer to a question I have asked: “Is the natural diet of the human even the optimal one?”
Let’s look at the 15% protein, which on the surface seems small. 2000 calories is considered average for an average man. So a reasonable starting point.
2000 x 15% -> 300 calories
Protein is 4 calories per gram
300 / 4 -> 75 grams of protein daily.
Now let’s look at Nora Gedgaudas (two books in my links). She (and others) recommend 0.8 grams of protein per kilogram of body weight. And desired body weight at that. We will use 140 lbs since that is my target, dream weight.
140 / 2.2 -> 64 kg (rounding up)
64 * 0.8 -> 51 grams of protein daily
And just for you average size people 180 lbs -> 65 grams of protein per day.
Put in “real food” terms Kast says 10 eggs per day and Gedgaudas says 7 (or 9) eggs.
So suddenly Kast is not so restrictive. Gedgaudas claims that the correct amount of protein is the size of the palm of your hand, using 3 meals per day.
Cannot comment on the vegetable protein at this point. I think the carnivore school would argue; however, his comments about restricting methionine (an essential amino acid) are basically quoted in the Wikipedia article on mTOR.
Curse it: now I am going to have to read the rest of the book to see what he says about Fats and Carbs. And how does this integrate with my growing feeling that (grass-fed) ruminant meat is the natural diet of humans? And what does the significant “carnivore” group out there say about all this?
For the record, Gedgaudas talks about mTOR, also. And I have seen it mentioned as part of the Diabetes/excess sugar problem.
A little about mTOR: it was discovered in 1993. Here is an extract from the Wikipedia article:
Wikipedia mTOR: mTOR integrates the input from upstream pathways, including insulin, growth factors (such as IGF-1 and IGF-2), and amino acids.mTOR also senses cellular nutrient, oxygen, and energy levels. The mTOR pathway is a central regulator of mammalian metabolism and physiology, with important roles in the function of tissues including liver, muscle, white and brown adipose tissue, and the brain, and is dysregulated in human diseases, such as diabetes, obesity, depression, and certain cancers.
