I literally started primal eating two days ago, but did my first shopping trip yesterday and spent less than $50. This gave me enough food for at least a week. But I'm a female so I eat less than you, plus I do two intermittent fasting days a week, so that saves some money there Also, a big part of it is where you live and what shopping options you have. My $50 may translate to $100 for where you live and shop. I am keeping it really simple, since I'm just starting out-chicken, veggies, eggs, some naturalish sausages I got on sale, and then I made Mark's tomato soup and spicy meatball recipes-both were cheap to make and will be several meals worth. Also, I'm loving tbe pancake/egg recipe that's posted in the recipe section-only costs a few cents to put together, takes a couple minutes to make and they taste awesome!
