I came across Raymond Cool (Norm) a while back and read his blog with interest. He's lost nearly 300 lbs on HCLF as a volume eater. Then I found his journal on McDougall's forums where he's a little less inhibited and talks about struggles as he got down to his current weight. It was easy for him at first but as the weight went down, things got harder. He started to regain and had to restrict calories. He got cravings as well.

I don't blame his situation on his diet though. Anyone with that much weight to lose is going to have many more fat cells than the average person and when the individual fat cells get too small, they start sending signals that starvation is imminent - even though there might still be a lot of collective fat among them.
