It pays to shop around, too. Here's $70 at my farmer's market:
Here's $70 shopping at my food coop and Trader Joe's:
I'll bet if I didn't want the grass-fed and organic stuff I could double the amount by shopping at a regular grocery store. I live in one of the most expensive cities in Southern California, it that helps explain why food is so expensive for me.
Note that all the crap trader joe's junk food is for him. I get steak and vegetables and he gets frozen pizza or tamales. Saves a lot of money and makes him happy he doesn't have to eat the food that's going to "kill him."
Also, as I've gone along, I eat only twice a day at most and a few times now I've eaten only once. And those meals were all normal sized, not extra large to compensate. So even though there's not a lot of food shown there there's still a lot left over in the freezer and fridge from last time.
