Fasting refers to complete abstinence from food for a short or long period for a specific purpose. The word is derived from the old English, feastan which means to fast, observe, be strict.

Fasting is natures oldest, most effective and yet least expensive method of treating disease. It is recognised as the cornerstone of natural healing. Dr. Arnold Eheret, the originator of the muscusless diet healing system, describes it as " natures only universal and omnipotent remedy of healing" and "natures only fundamental law of all healing and curing. "

The practice of fasting is one of the most ancient customs. It is followed in almost every religion.

The Mohammedan, the Buddhists, the Hindus and many others have their periods of strict fasting. The saints of medieval times laid great stress on this method.

Fasting indisease was advocated by the school of natural philosopher, Asclepiades, more than two thousand years ago. Throughout medical history, it has been regarded as one of the most dependable curative methods. Hippocrates, Galen, Paracelsus and many other great authorities on medicine prescribed it. Many noted modern physicians have successfully employed this system of healing in the treatment of numerous diseases.

The common cause of all diseases is the accumulation of waste and poisonous matter in the body which results from overeating. The majority of persons eat too much and follow sedentary occupations which do not permit sufficient and proper exercise for utilisation of this large quantity of food. This surplus overburdens the digestive and assimulative organs and clogs up the system with impurities or poisons. Digestion and elimination become slow and the functional activity of the whole system gets deranged.

The onset of disease is merely the process of ridding the system of these impurities. Every disease can be healed by only one remedy - by doing just the opposite of what causes it, that is, by reducing the food intake or fasting.

By depriving the body of food for a time ,the organs of elimination such as the bowels, kidneys, skin and lungs are given opportunity to expel, unhampered, the overload of accumulated waste from the system. Thus, fasting is merely the process of purification and an effective and quick method of cure. It assists nature in her continuous effort to expel foreign matter and disease producing waste from the body, thereby correcting the faults of improper diet and wrong living. It also leads to regeneration of the blood as well as the repair and regeneration of the various tissues of the body.
