My CDC said only to use Splener tablets as the least carbs! You could also split open a pack of vanilla shake and use e teaspoon to whiten, although I didn't like it much. But don't have more that one teaspoon per day! Good luck with the journey, you will soon see the benefits.
Thank you for your replies, I have four stone to lose, this is the largest I have been, I have to do this for my self and my children, just so I can go swimming with them in the summer, instead of just watching.
I have found this site very interesting, and supportive.
Good luck to your goals
