Fasting is not starvation

Fasting refers to the complete absence of food, surviving solely on water.
People have this misconception that fasting is the same as starvation, when in actual fact starvation can only occur after prolong fasting.

In general, fasts should last no longer than twenty eight days. Fasts that last longer than forty two days are both unnecessary and dangerous. A prolonged fast of two-three months is a slow form of starvation.
During a fast the body enters ketosis. This is caused when the body uses up readily available energy sources (food). Once that energy source has gone it starts converting nonessential tissue (fat), though conserving essential tissue. After the nonessential tissue have been used up the body then starts converting essential tissue thus causing starvation.

During a fast the ketone levels in the blood rise from 2.0mm to 3.0mm after a few days and continues steadily rising there after.

To reach starvation takes some forty two days or more thus proving fasting is not a form of starvation. Starvation is the latter stage of fasting and totally unnecessary.

Fasting burns only nonessential tissue where as starvation goes beyond the point until there is nothing left to burn causing serious illness and in most cases prolonged health problems, or even death.
