Most people experience a condition called ketosis when they suddenly go from a high-carbohydrate diet to a low-carbohydrate diet. This occurs when ketone molecules are circulating in the blood in a higher amount than on the previous high-carbohydrate diet. Ketosis is a normal physiological state caused by very normal and healthy body functions contrary to the myths,  distortions, and lies published by vegetarians and other high-carbohydrate diet supporters. Ketosis allows the body to function efficiently and live off of stored body fat when necessary. Ketones are not a poison which is how most medical and nutritional experts refer to them. Ketones make the body run more efficiently and provide a backup fuel source for the brain. The three substances known as ketone bodies are acetoacetic acid, beta-hydroxybutyric acid, and acetone. Some unknowledgeable people have an absolute fit when told that ketosis produces acetones in the blood, since acetone is a common household solvent. Acetone is commonly used as a fingernail polish remover. The body produces ketones as the preferred fuel for the heart, outer part of the kidneys, and most areas of the brain.

Ketoacidosis is a life-threatening condition commonly associated with Type 1 diabetes and insulin-dependent Type 2 diabetes. Ketoacidosis is not the same as normal dietary ketosis. The abnormally low level of insulin in the diabetic leads to a toxic build-up of blood glucose, causing excess urination, thirst, and dehydration. The glucose cannot enter the cells to produce energy in the absence of insulin. This causes the body to break down an excessive amount of body fat and muscle tissues for energy. Ketoacidosis is an unhealthy condition in which the body has excessively high glucose and ketone bodies at the same time. The ketoacids lower the pH of the blood to an unhealthy level. The body is very sensitive to changes in blood pH. The condition is never present in a non diabetic on a carbohydrate-restricted diet in which beneficial ketosis is achieved. Normal ketosis stabilizes blood glucose within a normal range and prevents the breakdown of healthy muscle tissue. The dietary restriction of carbohydrates prevents any build-up of excess glucose. The blood glucose level remains perfectly normal and stable, almost straight line. The body is actually powered normally by ketone bodies while we sleep. Ketosis was common and normal in all primitive people who lived on a high-protein, high-fat and low-carbohydrate diet such as the North American plains Indians and northern Eskimos. Dietary fatty acids and ketone bodies are very healthy fuels for the body in contrast to glucose which causes insulin resistance, diabetes, heart disease, and cancer.
