Hi.

>>"Is is possible to be in ketosis (not related to dietary fat) and not lose weight or inches?"

I would have to say no, since ketosis is specifically from the breakdown of fat (or muscle, if you're not eating enough.) Assuming it isn't dietary, it would have to be coming off your body.

Have you considered starting a journal and/or tracking your food intake for a while? If you post it, maybe we can have a look and see if anything jumps out at us.
