Fasting is a general term meaning to abstain. Most people use the word to mean eating nothing at all, but it doesn’t have to mean that. Just avoiding a few foods for health reasons or Lent is a kind of fast. We were not meant to eat absolutely every single day, really. Tests on single-celled organisms discovered that feeding them sporadically helped them to live 50% longer than organisms fed every single day.
Fasting is a fantastic way to restore and maintain vitality. It helps us to realize how few foods and protein we really need to make it through the day, a great way to reset the perspective that gets thrown out of wack by the standard American diet and commercials urging us to eat eat eat. Fasting is highly recommended for certain illnesses, chief among them is arthritis, general toxicity, digestive complaints including a coated tongue, adult-onset diabetes.
