No I'm a man. I was definitely in Ketosis, though the RFL diet isn't really keto, just a crash diet with an attempt at muscle sparing (i.e. "refeeds" to prevent a metabolic slowdown). So kinda sucks cause you get the flu going in and out of keto. It's been years since I did it but if nothing else enjoyed reading Lyle's books and articles. His ultimate diet is pretty cool, though extremely restrictive.
