[QUOTE="KennyA, post: 2609689, member: 517579"] I am running on ketones because my body is mainly using ketones, rather than glucose, for fuel. The ketones are derived from metabolised body fat (not dietary fat). I'm not sure that glucose is really the basic unit of fuel - we managed for tens of thousands of years on minimal carbohydrate consumption. I'm not a scientist and this I know is a very simplistic version. More here: [URL unfurl="true"]https://www.ruled.me/ketosis-ketones-and-how-it-works/#:~:text=Ketogenesis%20takes%20fatty%20acids%20from,for%20fuel%20is%20called%20ketosis.[/URL] Digested food is handled differently depending on what it is composed of. Carbohydrate is digested to glucose and is either used by muscles for fuel (assuming your insulin etc is working effectively) or converted to bodyfat or left in the bloodstream. If you restrict sources of glucose from carbohydrates, your liver uses two processes to fuel your cells — ketogenesis and gluconeogenesis. Ketogenesis takes fatty acids from stored bodyfat and dietary fat and converts them into ketones. The ketones are then released into the blood to fuel cells like our brain and muscle cells. The process by which the body burns ketones for fuel is called ketosis. Some cells always need to use glucose for energy. To meet the energy demands that can’t be met by ketones, your liver uses a process called gluconeogenesis where the liver converts non-sugar substrates like glycerol from fatty acids, amino acids from protein, and lactate from muscles into glucose. Together, ketogenesis and gluconeogenesis create the ketones and glucose that can meet all of the body’s energy needs when carbohydrates are restricted. [/QUOTE]
