I've probably read every significant diet book/scheme for the last 25 years. I also have 12 s.h. of college level dietetics and nutrition. Now, I'm not claiming that this makes me an expert, but whoever said don't go below 1200 calories a day is pretty much correct. Or at least that's what all my previous education tells me. Below that level your metabolism basically shuts down and does go into the aforementioned "starvation/survival" mode. It will begin to digest it's own muscle to preserve it's survival stock of fat. And as many of you have pointed out, muscle weighs more than fat.
The rule of thumb is that a moderately active individual (30 mins of exercise at least 3 times per week) requires an average of 15 kcal per pound of maintenance weight. So a lady who wants to weigh 120 would need an average of 1530 kcal per day. A guy like me who wants to hit a goal of 225 would need 3375 per day, at moderately average activity levels.
