Thanks guys, and thanks Mark, I just found a previous post of yours which Ladyshopper might also find encouraging!
Ketosis Myths and Facts
Hi Everyone, those who are not up to speed with Ketosis and do not understand the condition please read the below article. Just to make one thing clear, YOU DO NOT HAVE TO BE IN KETOSIS TO LOSE WEIGHT.
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.
Many people falsely believe they cannot or are not losing weight because the ketones drop to a lower level. However, weight loss continues with or without the ketones being present. The spillage of excess ketones in the urine disappears on the low-carbohydrate diet after the body becomes accustomed to using dietary fats for energy instead of glucose. This usually occurs within a few weeks on the diet. People who normally eat high-carbohydrate meals have been fueling their bodies with glucose and fructose obtained from the carbohydrates. Their cells have had very little experience burning fatty acids for energy. The body uses the glucose first to prevent high levels of glucose in the blood.
The body experiences a new condition when a person goes on the low-carbohydrate diet. The more commonly used glucose fuel is no longer available. The body reacts by dropping the pancreas' production of insulin and increasing the hormone glucagon. The glucagon draws stored fat reserves in the form of triglycerides for use by the cells as the new energy source. However, the cells are slow to react to this new fuel source, and the individual feels weak or lacking energy. The resistance to burning fatty acids for energy can vary greatly among individuals. Some people feel this weakness, but others pick right up and take off with the feeling of greater energy than before.
The liver begins to catabolize (break down) the extra fatty acids when they are not being utilized by the cells; however, the liver does not have the enzyme necessary for complete catabolism of the fatty acids. This causes the discharge of the ketone molecules into the blood. The strange taste in the mouth and mild breath odor shows the presence of these ketones. Other body cells can utilize the ketones for energy. The brain can utilize ketones contrary to the myth that the brain must be powered by glucose only; although, some areas of the brain still require glucose which the body makes from amino acids or fats. Ketones are the preferred energy source for the muscles of the heart.
The body begins to utilize the fatty acids for energy more efficiently after a few weeks on the low-carbohydrate diet, and the ketone level drops to normal. This does not mean a person is not losing weight. It means the body is becoming a more efficient fat burner.
The scientific and practical amount of carbohydrate needed in the diet is ZERO -- NONE. Dietary carbohydrates are not a requirement in any body function. In fact it appears that the lower the carbohydrate level in the diet the better the long-term health. Age-related degenerative diseases are caused by high levels of carbohydrates in the diet. One can be on a very low or zero-carbohydrate diet indefinitely as has been shown by the study of many primitive societies.
