producing fat from protein in wilderness

In cold climates many people crave fat.
I read that there is a great source of fat in wild nature: maggots If there is a carcass, there might be some maggot, and they transform the animal protein into fat. I heard of people using live maggot, and using them instead of butter. Sure, farming animals to make maggots, seems very inefficient, but in the wild, it can be a good opportunity.
Another way to get fat, but this time from sugar, is with waxmorms: they transform honey into very fatty grubs. But then you need to do some "farming" I guess, or you might be "lucky" to find a hive full of fatty waxies.

I think I'd just try to raise a pig!

I know many people eat insects, I guess I've just not there yet. .

I'd rather farm maggots to make animals!

Either way, you can't make maggots when it's this cold -going down to -18F tonight! That's why an animal like a pig makes more sense. You can store the fat on or off the hoof.

You know, I hadn't really noticed that this was in the wilderness: survival forum!

I guess that changes things. . . . in a survival situation I'd probably eat anything.
