Answer 1

Catabolysis. Your body resorts to protein for energy. It is really inefficient (producing something like an eighth the energy of ketosis, which is burning fat for energy). Muscle tissue degrades first as your body attempts to preserve things necessary for survival. Eventually your organ, which are smooth muscle, begin to breakdown as well. This is eventually fatal.
