KETOSIS and KETOACIDOSIS are two different things, although webMD obviously disagrees.
Ketosis is a state that indicates ketones are in the urine. ketones are a result of the body burning fat. They will be present if you eat a low fat diet and your body burns body fat. They are also present if your body burns dietary fat (they dont' indicate weight loss) and this is why the ketones are so obviously present on a low carb diet. from http://www.lowcarb.org/ketosis.html "Ketosis-Lipolysis is not Ketoacidosis" Maria C. Linder is on the faculty at California State University Fullerton, California in the Department of Chemistry and Biochemistry. All quotes are from her textbook; "Nutritional Biochemistry and Metabolism: with clinical applications", Maria C. Linder. pages 87-109. Chapter Eight: Nutrition and Metabolism of Protein. There is a difference between starvation, prolonged fasting and controlled carbohydrate eating. There are similar metabolic mechanisms at work, but the differences are key to understanding the safety and efficacy of controlled carbohydrate diets. "The whole process of muscle protein catabolism and liver gluconeogenesis is regulated principally by glucocorticosteroids and glucagon and a relative lack of insulin. Early in fasting glycogen reserves are depleted, and protein (mainly from muscle) becomes the major source of carbon for glucose production. Glucose is required in substantial amounts by blood cells and the central nervous system on a daily basis. There is also an initiation of ketone body production by the liver to provide a more water soluble form of fat-derived fuel." THIS IS WHERE THE CONFUSION BEGINS "A very similar adaption of protein and energy metabolism occurs in persons consuming diets very low in carbohydrates, where there is little or no glycogen reserve. However, in this instance, DIETARY PROTEIN largely or fully SUBSTITUTES for muscle protein in gluconeogenesis. NOTE: "DIETARY PROTEIN LARGELY OR FULLY SUBSTITUTES FOR MUSCLE PROTEIN IN GLUCONEOGENESIS." Even when discussing starvation most critics of lowcarb miss the mentally adept boat. "The body adapts to starvation and reduces the need for protein-dependent gluconeogenesis by boosting its production of ketones, a fuel ALTERNATIVE to glucose for MOST CELLS. Circulating ketones reach maximum levels after about ten days of fasting and now substitute for much of the glucose requirement of the central nervous system. This drastically reduces the need for catabolism of muscle protein." "With reduced protein catabolism, urinary nitrogen excretion also declines. And there is a shift from the excretion of urea to a predominance of ammonia loss. This shift toward ammonia versus urea parallels the increased production and excretion of keto acids, and serves to MAINTAIN ACID/BASE BALANCE." "The overall point is that muscle is a valuable reserve of carbons that can be used for glucose production when needed. However the body prevents excessive losses of muscle protein over long periods of fasting by adapting the central nervous system to utilization of ketone bodies for fuel." "A parallel adaptation in the production and excretion of ammonium ions by the kidney neutralizes the increased ketone bodies (principally beta-hydroxybutyric and acetoacetic acids). Without the latter adaptation, such large productions of keto acids would cause a severe ketoacidosis, as well as a loss of large quantities of sodium and potassium ions (accompanying ketones spilled into the urine)." Therefore, unless one is an insulin dependent diabetic or literally starving TO DEATH due to a lack of food, there is little or no danger from ketosis which is not characterized by a simultaneous RISE IN BLOOD GLUCOSE and BLOOD ACIDITY. ----- Original Message ----- From: "Ben Braver" <[EMAIL PROTECTED]> To: "CF-Community" <[EMAIL PROTECTED]> Sent: Friday, November 22, 2002 7:27 AM Subject: RE: Adkins > Yes, it makes your breath reek. > Your body goes into ketosis, and the smell is blowing off acetone. > > Atkins screws up your whole metabolic balance in much the same way as acute > starvation or severe diabetes. > > see WebMD article: > http://my.webmd.com/content/asset/miller_keane_18249 > > IMHO, the only diet that really works without messing up your health is to > decrease total calories as part of a nutritionally-balanced diet, and > increase calorie expenditure through aerobic and other exercise.
