what would be the minimum amount of protein you would suggest I take. I've been trying to have a bit more fat to induce ketosis quicker and it seems to work, but I wanto know how low I can go with protein before I start losing muscle mass!

I think I've seen something like 0.9, your thoughts???

I think I remember reading the minimum amount to maintain nitrogen balance was .8 per kg, but that was not conducted on LC subjects.

Since you can assume some protein will be used for fuel on this diet, I wouldn't drop below a protein ratio that is 40% of your daily calories ... about 5% is carbs, and the rest -- 55% -- is fat (25% unsaturated and some MCTs, 5% fish oils, and the rest being monounsaturated and saturated)
