8 ounces (by weight) heavy cream
4 ounces butter
6 ounces meat or cheese
10 ounces spinach
1 large egg
6 grams of cashew nuts (this is how I enter sugar free cashew "milk" into fitday).

This is pretty typical. The spinach is in there pretty much every day because it seems to be the best veggie for soaking up butter, but often it'll be about half that much spinach and the other 5 ounces some other low carb veggies. Once or twice a week there'll be some sort of social eating, that drives my protein intake up for those days. Other days if the planned food leaves me hungry, I'll have some extra heavy cream with cocoa powder or some hot flax seed cereal, to keep the fat ratio high.

Might seem a little orthorexic, but a few years ago when I first tried a more structured form of ketogenic diet, I stopped having auditory hallucinations I always had when using loud machinery. So I guess, pick your crazy.
