In nature cure, one of the very important tools for health and disease cure is
fasting. Many people are learning the trick of curing their colds, headaches, nervous spells
and other acute troubles by missing a few meals or taking a short fast. It is the simplest and the most efficient way of relieving the overloaded and "foodpoisoned" system. You would be surprised to know
how little food is actually required to keep the individual healthy.

One of the commonest complaints of the sick is that they have "lost their appetite".
In fact, the greatest blessing to them would be to lose their appetite long enough to
find their hunger. Loss of appetite is an indication that the system is overcharged with toxins and nature is trying to correct this by giving a chance to the waste accumulation in the organs to escape from the system.

Fasting as a remedy is fully in harmony with the "naturecure" philosophy of the cause
of disease. If the disease is created by an abnormal accumulation of toxins in the system, it stands to reason that fasting will help in their elimination from the system. The membranous linings of
the stomach and intestine which act as a "sponge" to absorb food materials are now "squeezed" to throw out the waste matter from the system.
