i believe the "shut down organs and body starts consuming muscle" part is applicable in the death zone of mt. everest. However, it does not apply anywhere else in the world. The body burns FAT first, because that is where the excess calories go.
Basically, you lose FAT if you expend more calories than you consume.

Sorry but that advice is not only incorrect, it's dangerous. It sounds like the kind of rubbish anorexics tout. Please, talk to a doctor or nutritionist before giving this sort of advice. It's a very unhealthy attitude.
Our bodies are very clever. When they detect we aren't getting enough energy, they adapt by chewing down on muscle reserves. Muscle takes lots of energy just to maintain. Just resting, fat takes hardly any calories to maintain, while muscle takes HEAPS. The more extreme the shift in diet, the more your body will try to defend it's fat supplies for the long haul, while slowing down organs and eating away at muscle to reduce the amount of energy needed to survive.
This is one of the problems that healthy dieters have. Once they finish a diet, they've lost some of their muscle mass, so they don't need nearly as much energy to maintain their weight anymore. Then once they finish the diet and go back onto regular meals, unless they do lots of resistance training to build muscle up afterwards, their body stockpiles fat again. It can also be why that the longer you are on a diet, the less weight you loose, because your body has adapted to it's new energy input.
Quite simply, drastic changes in body shape are not healthy. Aim for 2.2 pounds a week, with some resistance training and you probably wont loose to much muscle. Hell, even though I was loosing under 1kg (2.2 pounds) a week, upping exercise rather than just lowering caloric intake and doing resistance training, I still lost about 5kg of muscle when I lost 20kg in 10 months.
