Don't worry too much about the keytosis thing, some put far too much memphasis on keytosis and end up getting disheartened - you can register a low keytosis if you are drinking plenty - it dilutes things and also you can actually be burning loads of keyto's and still register a small reading - it doesn't always make sense!
You sound like you're doing well - keep up the good work and in no time you'll begin to lose inches and weight!
