I think it just varies from person to person as far as weight loss on the diet, as well as where your fat gets stored. Some of it could be candida-related, but things like that also come from genetics, your metabolism, etc.
Also, I know at least one person on here was on the diet for quite a long time (like a year, maybe?) before she suddenly started dropping pounds.
I would just be more concerned with getting healthy, like Shayfo said…eventually, when you get rid of the infestation and heal your body, you will reach whatever weight/shape your body naturally wants to be in.
