Let's have a quick look at
Wikipedia:
"Early symptoms include impulsivity, irritability, and hyperactivity.
Atrophy (wasting away) of the stomach weakens the perception of hunger, since the perception is controlled by the percentage of the stomach that is empty. Individuals experiencing starvation lose substantial
fat (
adipose tissue) and muscle mass as the body breaks down these tissues for energy.
[6] Catabolysis is the process of a body breaking down its own muscles and other tissues in order to keep vital systems such as the
nervous system and heart muscle
(myocardium) functioning. The energy deficiency inherent in starvation causes
fatigue and renders the victim more
apathetic over time. As the starving person becomes too weak to move or even eat, their interaction with the surrounding world diminishes. In females,
menstruation ceases when the body fat percentage is too low to support a fetus.
Victims of starvation are often too weak to sense thirst, and therefore become
dehydrated. All movements become painful due to muscle atrophy and dry, cracked skin that is caused by severe dehydration. With a weakened body, diseases are commonplace. Fungi, for example, often grow under the
esophagus, making swallowing painful.
Vitamin deficiency is also a common result of starvation, often leading to
anemia,
beriberi,
pellagra, and
scurvy. These diseases collectively can also cause
diarrhea,
skin rashes,
edema, and
heart failure. Individuals are often irritable and lethargic as a result.
There is insufficient scientific data on exactly how long people can live without food.
[7] Although the length of time varies with an individual's percentage of body fat and general health, one medical study estimates that in adults complete starvation leads to death within 8 to 12 weeks.
[8] There are isolated cases of individuals living up to 25 weeks without food.
[9] Starvation begins when an individual has lost about 30% of their normal body weight.
[10] Once the loss reaches 40% death is almost inevitable.

Now, with this in mind, can you answer my questions ?
