Welcome Karen
Your first post is in the "right bit" and there are so many other bits to explore to help you
I enter the forum through this index page http://forum.lowcarber.org
...you can see the organization of topics and sub-forums. Start reading back through a few pages on the topics of interest. In the media/research..we have that BBC special posted. http://forum.lowcarber.org/showthread.php?t=480472
I personally follow a lower carb diet and would not consider messing around with freezing bread or chilling pasta to make "resistant starch"...like you I would just cut it out completely. But this forum supports many LC programs so look around. It was a good program to inspire folks, esp. someone with diabetes. Dr. Unwin is the best!

Great start! Much of the weight loss in the first week is water...but that is a good thing! here's a thread that explains it. http://forum.lowcarber.org/showthread.php?t=365499

All the best
