Also: a glass of half and half? Really? I get the milk carb thing, but why not just drink something with no carbs or fat?
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.
I agree, don't eat Wendy's (it will also kill you), and I salute you for operating almost entirely on dairy fat, but I think my point stands: it isn't necessarily or even likely cheaper to cook than to eat out.
For food of the same quality, cooking at home is cheaper. The absolute minimum cost of either food is comparable (corollary: there is worse fast food available than you could cook yourself).
