> high fat and you can eat a lot of fat very quickly and get a lot of calories that way

Fat also has the lowest thermic effect, a paltry 2-3%. Besides having the most calories per gram (9 vs 4 for protein or carb), it provides by far the cheapest, easiest calories for your body to digest.

Well I am not too sure about that cheap easy calories as far as fat goes.. as far as the price yeah oils not too expensive but Meat is not cheap and meat is really the way you have to get most of the calories in fat... Easy to digest? Starchy carbs far and away the easiest

I mean metabolically cheap and easy. Your body expends the least energy digesting fat (2-3%, or 2-3 calories worth of energy for every 100 fat calories you consume), and the most digesting protein (>20%). Add to that the fact that fat has more than twice the calories per gram that carbohydrate and protein do, and it's little wonder why so many people fail with keto.
