I have a few questions, please
 

Hi, I have a few questions pertaining to the Atkins diet. Here goes ...

(1) Why was the concept of Net-Carbs introduced? Atkins never used this concept in his books. It must have been introduced after his death. What is the reasoning behind it ?

(2) I want to get some protein bread. I would rather make it myself. This would require some Soya Powder. Where can I buy soya powder. I've looked everywhere: health food stores, Chinatown. Nobody has it. If I order it from the internet it would likely cost a lot due to shipping. Can I make protein bread with something else?

Thanks in advance!
