Grease, that is to say animal fat, has been consistently, and inappropriately, demonized by the entirety of the governmental and private medical establishment for the last sixty years. Now, the word "grease" conjures up mind images of a sticky icky yucky, double plus ungood threat to one's health. Nothing, and I mean nothing, could be further from the truth. Grease is good. Animal fat is good. Bacon fat, tallow, and lard, is good. It is good for virtually every organ in your body, especially your brain. And the older one gets the more important it becomes.
It is unfortunate that "grease" is also used to describe thick mechanical lubricants. Something the average person is keen to get washed off his hands. "Greasy" food is considered just about the worse thing a person can eat. Ironic in the extreme since the grease is likely to be the healthiest part of a typical fast-food meal. And this is accounting for the fact that in most cases animal fats have been almost entirely replaced by "heart-healthy" (not) seed oils.
My way of eating averages out at about 50/50 fat and protein by weight. In terms of calories the ratio is about 80/20 fat/protein. I am absolutely thriving on that ratio, in every respect, and plan to continue eating this way into the misty future. Which is very likely to be much much longer than it would have been just six years ago. Animal fat and protein abetted our species' rise to sapience several million years ago. There is no reason to not continue to adhere to that biological imperative.
