In general i disagree with CICO, mainly because it is impossible to place a fixed calorie number for anyone and say, eat more and gain, eat less and lose. It will vary greatly depending hundreds of factors. In a perfect world, one would never need to calorie count because the body would dispose of excess calories without needing to store them and regulate other processes when calories are deficient. When a person gains fat, there is almost always something wrong, be it environmental stress, hormone issues or something else.
I didn't read through the thread... too long, but my first reaction is that dietary fat is the only thing that doesn't affect blood sugar. Going lowfat seems like the last thing you would want to do. Maybe you need to lower protein a bit more and up your fat. Nora Gedgaudas is a good resource for you right now. You can listen to some of her podcasts for great info.
I am not going to eat low fat. I have updated this thread a few times, but people don't seem to be reading it.
