I'm frugal.... or maybe just a tight wad. Personally I cook my fatty meat first then just throw what I'm gonna be eating with that meat in the same pan (i.e. in the fat from my cooked meat) to cook..... that could be veggies, squash, starch.... whatever. It always turns out excellent and I don't have to spend one extra penny or pour any extra oil on it and I'm still a high fat guy. I use lots of EVOO on salad cause I must (bacon grease can work.... but not all fat makes a good salad topper). I use little butter and less coconut oil. My wife on the otherhand likes to "bake paleo" and goes through a literal ton of the stuff when its her day to cook.

Dietary hierarchy is: Fatty and gelatinous meat/eggs/seafood/offal > raw and fermented dairy > nuts and seeds > fruit > starch > veggies > everything else.
Backyard permaculture, gardening, and fermentation as healthy hobbies. Lift heavy stuff and move a lot.
