Just curious where everyone gets their fat from. I've got heavy cream and coconut oil, the latter is much more dense in terms of calories from fat, but both aren't cheap. I'm single, and I end up spending at least $70 at the grocery store every week. It'll be even more than that per week when the grass-fed CSA starts. Aside from coconut oil, I snack on nuts, because even after a meal, I'm typically still a little hungry. I try to keep my nut consumption to just Macadamias, since they're supposedly the healthiest, but they're damn expensive.
I'd eat more eggs, but those seem pretty expensive too for non-supermarket brand, and eggs rarely fill me up. The only way I think I can really cut the cost is by buying high fat ground meats, but then I'm a little limited with the meals I can make from that.
I know the cost of food has been discussed, I'm just specifically curious about getting more healthy fat, cheaply.
