It's the "eat more" that I don't agree with. That is seriously bad advice for food addicts because your brain will convince you of crazy things in its desire to eat and my experience is that you should never give it any room for excuses.
I'm 5'11". I achieved my lowest weight about 2 years ago and have managed to keep off all but 10lbs of it, much of which I'm confident is muscle. It took me 4-5 years to hit the low mark.
I didn't mean to imply that 44lbs was insubstantial, rather that I've had to operate at a different scale and so have a different perspective on what works and what doesn't.
