Yes, read the book. Yes, staying at 20 carbs. Yes, in ketosis. Yes, drining 80-100 oz of water a day (or more). Havent measured but go by how my clothes feel but NO looser.

And I think the only reason I blew it on vaca was because I hadnt lost in four weeks of being very strict. Otherwise, I found staying on this diet very easy. Never cheated in the 4 weeks prior to vaca.
