Conclusion    Starvation results from the inadequate intake of
nutrients or the inability to metabolize or absorb nutrients. It
can have a number of causes such as prolonged fasting, anorexia,
deprivation, or disease. No matter what the cause, starvation
takes about the same course and consists of three phases. The
events of the first two phases occur even during relatively
short periods of fasting or dieting, but the third phase occurs
only in prolonged starvation and can end in death.   During the
first phase of starvation, blood glucose levels are maintained
through the production of glucose from glycogen, proteins, and
fats. At first glycogen is broken down into glucose. However,
only enough glycogen is stored in the liver to last a few hours.
Thereafter, blood glucose levels are maintained by the breakdown
of proteins and fats. Fats are decomposed into fatty acids and
glycerol. Fatty acids can be used as a source of energy,
especially by skeletal m
