Its probably closer to what we spent generations evolving towards than the typical diet of shoving processed meats + Big Gulps in your face hole 19 hours a day.That's kind of two extremes though, isn't it? You fast, or eat crap?
And people get all upset about eating animal fat in quantities equal to protein, but that's what we did until the 70s. Then we stopped, and everyone ended up overweight.
So I agree, traditional diets seem best, and maybe a fast or two. But if we fast, it should be in the late winter, and we should faten up in the late summer/fall too, yes?
That's most inline with humans prior to cities/agriculture.
Then again, we have what... 20,000? 50,000? generations of humanity using animal husbandry, and farming, to change that cycle?
