I started a thread somewhere on this book (but can't remember where LOL). It's a mother & daughter who wrote the book with the help of the husband who is an MD--so he kept them "honest" on the physiology. They do indicate that 12 cal/pound may not be right for everyone, but have some good science to suggest that is the case. I'm doing my counting a little different than them, but I'm tracking everything at this point in time and basically trying to find if--FOR ME-the 12 cal/pound is a reasonable estimate of what I'm burning (it's turning out to be). I eat below my maintenance level right now because I need to drop some weight a bit faster to make my hike next year w/o blowing out my knees
I find their approach refreshing and they do make the exceptionally valid point that if you calculate your maintenance calories and try it out and it is just not something you can live with long-term, well....then you have a problem and maybe you're aiming at too low a goal weight. Instead of presenting a "diet" they just give you your new lifestyle.
