Well, you’ll have to do some experimenting, I think. If you find that, no matter how much fat you eat, you are still hungry, you probably need more protein. If you find yourself tired and cold all the time, you definitely need more protein. If you start smelling of ammonia, you are eating far too much protein. There’s a broad range in which you’ll be fine.
I don’t remember if you said how long you’ve been eating ketogenically, but at the first, it pays to simply eat. If you eat till you’re full and find yourself hungry a couple of hours later, then eat again. It can take a while for the hormones to re-regulate themselves, and that is true both of the hunger/satiety hormones and of women’s cyclical hormones.
Having watched several of Dr. Phinney’s lectures on YouTube, when I went keto I continued to eat my usual platefuls of food at meals until, one day in the middle of lunch, I suddenly wasn’t able to eat any more. So I put a half-plate of food in the fridge and didn’t eat again until supper, many hours later. It was my first experience of satiation, as opposed to being full, and it was an eye-opener. After that, my appetite was more moderate than it had ever been, though I still continued eating three meals a day. About a year after that, I stopped eating in the morning and began eating only two meals a day. And just recently, I found myself not eating until about 8 p.m. It wasn’t by conscious choice; I simply wasn’t hungry and didn’t think about food. But then there are other days that are very different. I just relax and figure my body knows what it’s doing.
