I use soy protein isolate, virgin coconut oil and virgin olive as my staples. I also eat 3 eggs a day. I'm around 10% calories from fruit but zero starch. You can play around with what works best for you but the first question I wild ask is why do you want to do keto? I do it due to an idiosyncrasy between my diet and my genetics which causes unbearable inflammation if I eat lots of carbs and sugar like a normal western diet. If I didn't have ankylosing spondylitis there is no way I would be doing this.
