I spoke with C. again the other day. She is still losing the weight but is still hungry - all the time. I tried to talk some sense into her. She's a 6, looks great, how can she live like this? But, she is still babbling about becoming a size 4.
She's not on line so I plan to print up this article from Style Bites about this very issue - it's worth a read for anyone thinking about where and when to draw the line.
