单词	ketogenic
释义	ketogenic /ˌkiːtə(ʊ)ˈdʒɛnɪk / adjective Relating to or causing ketogenesis: if you are supplying less than 100 grams of glucose, you will be putting your body into a ketogenic state... The main pathway for tyrosine degradation involves conversion to fumarate and acetoacetate, allowing phenylalanine and tyrosine to be classified as both glucogenic and ketogenic. The products of this reaction are both ketogenic (acetyl-CoA) and glucogenic (pyruvate). However, while both the Atkins and South Beach low-carb diets warn people not to stay in the extremely low-carbohydrate ketogenic "induction" phase for more than two weeks, many people, like your friend, choose to do so for months. Origin Early 20th century: from ketone + -genic.
