I do my own thread. But i am just popping in to say i've read your thread and wish you all the best.
You can use your thread as a sort of record of what you are doing. I do that on mine. I food diaries and talk about anything else and like you only list my weigh then its reaches a new low. Because i feel i have to justify it if its goes up which i think stupid and don't want to do.
Anyway its good you realised you haven't got a metabolism problem. I found a website recently called nutrition world which has some good articles about the interplay of certain hormones and weightless. As a yo yo dieter you might find it helpful. Leptin, seratonin and insulin as well as fibre are all interesting articles i found there under the UNDERSTAND YOUR BODY section. I need to read them again actually. There's a lot of info in them to try to absorb.
