It has changed my life. When I follow the diet, it has been pretty impossible not to lose weight. That's with eating as many eggs, as much butter, and as much natural, delicious, other whole foods as I can stuff myself with.
However, the metabolic science is there if you read it, and I can't argue with the profound effect switching to a diet based on meat, eggs and other sources of saturated fats has had on my body.
I eat as much as I want, whenever I want, I'm never really hungry any more, and I've been losing fat and gaining muscle without thinking about it at all. It's pretty incredible.
Humans are no longer subject to natural selection. There needs to be significant culling pressure for real evolution to happen.
What? Are you sure? Because we most certainly are subject to natural selection.
A more obvious example of the sorts of changes we can still go through is sickle cell.
Evolution is a slow process. But there is no reason to believe that it is going any slower today than it ever did in the past - we're just being selected for different things than in the past. (For instance carelessness about birth control.)
Think of it this way: we used to be directly reliant our the environment for survival, like animals are. But now, we process our environment to such an extent that small variations in it are overcome by our intellect. Those variations in the past would constantly be exerting selective pressure on us in many different directions. Those pressures are processed out now.

And anyway, I completely disagree that we're no longer subject to natural selection. We're always subject to natural selection. We're not immune to everything.
