Continuing to point out some of the many fine evolutionary fitness resources I'm coming across, here's the blog of UK veterinarian Peter who since 2003 has existed on a diet whereby 80% of his calories are derived from animal fat. Says he feels better than when he was a teenager, and given my own recent experience with intermittent fasting and high animal fat intake, I'm not doubting it. There are a ton of great posts — take your pick. This one on self-evident fat metabolism from an evolutionary perspective is good.
It's really the evolutionary perspective in all this that's crucial for me. Accordingly, I have come to view much of what I see in modern diet and fitness as the equivalent of modern philosophy — where man's nature as a volitional being that must choose and produce his own values is never properly integrated. How man hungered and pursued the value of food; what he chose to eat, how long he went in-between, how he expended energy in acquiring food, and how he ultimately survived and evolved in the wild ought to form the basis, the premises, the starting hypothesis in all we undertake to understand. Accordingly, the diets of the last 10,000 years — up against 2 million years of evolution — really ought to be held in great suspicion when they contradict what was likely the sorts of diet that evolved our genetic makeup.
And really, just look around. The obesity is astounding and for some of us it's simply inevitable we're going to get fat eating like everyone does. Should it really be a surprise that in deciding first to go hungry, and then eat in a manner as one may reasonably presume primitive peoples did, that weight drops precipitously and we begin to feel as good as we did as kids (I slept 9 1/2 wonderful hours last night, and "went to bed on an empty stomach" without dinner).
I think we're on the verge of some reality in all of this over the coming years. Here are three big subjects to watch for: Intermittent fasting, which I've blogged a lot about; potential benefits of no-low carb, moderate protein, high-fat diets; and the possible causal link of inflammation to a great number of our health problems and how our diets promote inflammation.
With regard to inflammation, I suspect that it's the fasting and very low carbs that have resulted in me getting off two prescription medications in the last month that I've been on for years, one for chronic heartburn, the other for year-round nasal allergies.
