I do what I call lazy keto. I've been doing it a long time because I used to call it lazy Atkins induction.
Fewer than 2k calories and twice as much fat as protein. Easy-peasy; no need to count micronutrients or follow some complicated diet plan.
I seldom eat any salad greens at all. Mostly it's cheese, meat, nuts, fish, cream, olives, with occasional flax, millet, or coconut.
No chicken and only occasional egg yolks because without them my former arthritis/bursitis is completely gone (I have the arthritis/bursitis diet a doc gave me, if interested, let me know).
Supplemented with a lot of water, a few cups of coffee and/or tea (with organic heavy whipping cream) and an occasional glass of red wine (no more than one 4oz glass per day).
Since I don't eat hardly any fruit or veggies, I take supplements that have fruit and veggie extracts. (Life Extension Mix with Extra Niacin.)
I'm 74½ years old, on zero medications, and a heart/circulatory system of a 50 year old according to a heart doc. I guess I don't need the greens. It's obviously working for me - YMMV
The crisper is full of imported European cheese, Cheddar, Havarti, Brie, Pecorino Romano, Parmigiano-Reggiano, Gouda, Provolone, Edam, Scamorza (when I can find it), Alpine Swiss, Asiago, Mascarpone, Mozzarella (especially di bufala), etc. European cheese because it's from A2 cows and my DW is intolerant to A1 dairy. Plus the Euro-cheese isn't saturated with synthetic hormones. I tend to shy away from part-skim cheese - the taste is in the fat.
