可以「行」行gluconeogenesis的amino acid叫做gluconeogenic amino acid,當中包含BCAA,但有好多AA例如alanine(非 BCAA)可以變做pyruvate然後gluconeogenesis變glycolytic intermediate。

"Some popular high-protein/low-carbohydrate diets limit carbohydrates to 10 to 20 g/d, which is one fifth of the minimum 100 g/day that is necessary to prevent loss of lean muscle tissue
這明顯是錯的,有ketone bodies存在的話係唔會消耗肌肉的 (好多VLCD的例子表明唔會耗肌肉,機制應該係依靠抑制 branched-chain-2-oxo acid dehydrogenase)
仲有教科書 McArdle WD, Katch FI, Katch VL. Exercise Physiology: Energy, Nutrition and Human Performance. Philadelphia: Lippincott Williams & Wilkins; 2001
"low-carbohydrate diet sets the stage for a significant loss of lean tissue as the body recruits amino acids from muscle to maintain blood glucose via gluconeogenesis ''
錯!錯! 錯! 完全無視咗ketone bodies 的存在!
