Arf at BIWI getting all het up!!
I am getting de ja vous of the good ol' days with Lovecat and me, and you BIWI, (among others) trying and failing to explain it to all the newbies! It was funny opening that link after all this time.
BIWI and I were on there as regulars together - God, must be getting on for 10 years ago now.
Look people, this not an easy thing to grasp, and as BIWI says it can be VERY counter-intuitive at first, but in order to do it properly, for it to work, and for you to have faith that it works and is not dangerous you need to understand it. Read a decent book!
Even then, it takes a massive leap of faith the first time. But you will soon see the light, and the error of your previous deluded ways. 
I haven't read the whole thread or the previous thread, so forgive me if I am repeating old advice but you need to go onto Amazon and look for:
Robert Atkins
Dr Briffa
Leslie Kenton
Gary Taubes
I do recomment the India and Nerys book but I would highly recommend you read one of the original ones written by a sciencey person/doctor/dietician first to better understand the science behind it. The India and Nerys is very user-friendly and jolly, but I think in order to really have faith you need to get to grips with the heavy stuff. It's not that dry a read really, in fact I found it all fascinating. It throws so much light on how manipulative the food industry is, and why we have such a hopelessly fat society today.
