I've selected 2 key metabolic ingredients, Acetyl CoA and Citrate, to explain nutrition metabolism in further detail. I've also selected a different storyline, the mitochondrial amusement park and the Kreb's merry-go-round, to help you visualize some of the most fundamental steps of metabolism. In this episode we cover: Acetyl CoA's role as a key metabolic conductor The metabolic merry-go-round used to explain Kreb's cycle The importance of the Citrate sensor in switching between anabolism and catabolism How these concepts are tied to the root cause for weight gain and insulin resistance A critique of B-vitamin supplements as "energy producers"
