Physiological ketosis is the non-pathological (normal functioning) elevation of ketone bodies that can result from any state of increased fatty acid oxidation including fasting, prolonged exercise, or very low-carbohydrate diets such as the ketogenic diet. [5] In physiological ketosis, serum ketone levels generally remain below 3 mM. [1]
Ketone bodies are water-soluble molecules or compounds that contain the ketone groups produced from fatty acids by the liver (ketogenesis). [1] [2] Ketone bodies are readily transported into tissues outside the liver, where they are converted into acetyl-CoA (acetyl-Coenzyme A) – which then enters the citric acid cycle (Krebs cycle) and is oxidized for energy.
Russell Morse Wilder, at the Mayo Clinic, built on this research and coined the term "ketogenic diet" to describe a diet that produced a high level of ketone bodies in the blood through an excess of fat and lack of carbohydrate. Wilder hoped to obtain the benefits of fasting in a dietary therapy that could be maintained indefinitely.
Drawbacks: The goal of the keto diet is to put the body into a state of ketosis so that it burns fat instead of carbohydrates. Lazy keto may not lead to ketosis. Related: 10 Keto recipes to try ...
Prolonged fasting (also called extended fasting or water fasting) involves periods of fasting above 24 hours, typically in the range of 5–20 days. [13] In early fasting, the body operates under a relatively high level of gluconeogenesis , though this eventually decreases as the body's metabolism switches into ketosis , causing ketones to ...
The accumulation of acetyl-CoA in turn produces excess ketone bodies through ketogenesis. [11] The result is a rate of ketone production higher than the rate of ketone disposal, and a decrease in blood pH. [12] In extreme cases the resulting acetone can be detected in the patient's breath as a faint, sweet odor.
The brain uses these ketone bodies as fuel, thus cutting its requirement for glucose. After fasting for 3 days, the brain gets 30% of its energy from ketone bodies. After 4 days, this goes up to 75%. [6] Thus, the production of ketone bodies cuts the brain's glucose requirement from 80 g per day to about 30 g per day.
