Well, I don't have much advice. I'm afraid we spend a fair chunk on our food.

But I do have some thoughts.
Shop at the farmer's market as much as possible. You can get some really good food there, and usually for less.
Get a freezer if you can. Or ask for one for your birthday/anniversary/Christmas present. That way you can buy in bulk and save.
As for the animals, I'm not sure which ones you mean. But there are things you can do without having a lot of land. You can buy a steer and have it butchered. You can either ask around and find someone willing to sell to you before "finishing off" the animal on grains, or you can find someone willing to let your cow run with theirs until you're ready to butcher.
OR, depending on where you live, you might be able to get a lease on some BLM (Bureau of Land Management) land. We've done that. We happen to have to land right next to some BLM land, which gives us first dibs. But you can certainly apply for land that is away from land that you own (or don't

). You aren't guaranteed to get it, but if you do, you could raise some animals on it, and it's not very expensive (we pay $35/yr.). The BLM tells you how many animals the land can sustain. We are allowed 2 cows year-round. We didn't do it this year, but we will next year. Then you could buy a couple cows, raise them on the land, and then have one at a time butchered (there should be at least 2 together, so you'd want to kind of rotate through, always replacing the one that is butchered), and maybe share the cost (and meat) with some other like-minded folks. Unless the land were
very close, it would be hard to raise chickens on a lease. Anyway, I don't know how feasible that is for you, but thought I'd share.
I get my coconut oil from Mountain Rose Herbs (the unrefined). It's the cheapest way to get coconut oil that I've found, even though they've raised prices recently. You can click through the link "Buy Herbs" on the upper left of any MDC page and then you help support MDC in the process.
Some people suggest that you don't throw out the food you have. Use it up and just replace it with the kind of food you want to eat. We didn't exactly do this, since we went GF at the same time, so we
had to get rid of the gluten (which was in a lot of the packaged food we had). I suggest that if you can afford to just replace it, or if your health dictates that you change right away, you go through and give away (to a friend or a food bank) all the food you want to get rid of, and then replace it. But either way, don't just replace it with replacement foods (foods supposed to be just like what you're throwing out but healthier in some way). Instead, get good food, like what you plan to be eating. For us, that's healthy meat, eggs, veggies, fruits, fats, and nuts.
Anyway, I'm out of ideas. But there are a lot of good ideas floating around here. I'm sure some folks will chime in here, and you can look at old threads about TF on a budget. There are several, and one was fairly recent (something like "How do you do it?").
Good luck, and be patient with yourself.
