Yeah, if you can get a good source of meat, tallow is good stuff. We bought a beef quarter a few months ago, and it came with a huge bag of bones, which I roasted, rendering a few pints of tallow that I saved for cooking. It adds a great rich flavor.
Do look into coconut oil more. It's saturated fat, but quite a bit different from saturated animal fat. I haven't had enough coffee this morning to remember all the details, but it's processed differently in the body. I'll eat a spoonful of coconut butter for a quick shot of energy before a workout, and it's way better than snarfing down a bunch of carbs.
I've been maintaining a 50# weight loss for over two years now while cooking with coconut oil, ghee, tallow, bacon grease and olive oil, eating coconut butter, nuts, and putting heavy whipping cream in my coffee each morning. I've recently gained back about 8# because I've been trying to use up potatoes I grew last summer and the random rice and other starches I have stored in the pantry. I expect this will fall off soon enough if I drop my carbs back down to ~100 grams/day.
