Hi
I have been sugar free (well, as much as possible) since September when I heard David speak at a conference I attended. He is such a nice guy, by the way.
I also use 'My Fitness Pal'. I am not sure about the blogging, never done it and was wondering if there is somewhere on "My Fitness Pal' to do that, otherwise I am not much help, but as no-one else had replied, I wanted to welcome you and wish you well.
I have lost very little weight since starting. but feel way better and not bloated. I also used to get diarrhea but not now, so it must have been the sugar.
I have to be careful not to make too many of the dextrose based recipes (only for special occasions) as dextrose still has lots of calories. I have made the Ice-cream and enjoy that, especially as an affagato (Ice-cream with Espresso).
I believe that exercise is the key also but hate doing it, so try to do small walks and use the XBox Dance Central for fun exercise.
Good Luck.
