It's more about convenience and I what I like, actually. No real effort to each cheap. I like eggs and I like whole fat dairy. And in truth I do often eat cod or flank steak or whatever, so up the daily cost by maybe 50%, but it's still peanuts compared to eating out.
> a glass of half and half? Really?
I go through half a stick of butter, a glass or two of half&half, and some whole fat yogurt daily. First, it's delicious. Second, dairy fat is frickn diesel. You can run on all cylinders for ages.
