Amber Wilcox-O’Hearn explains why.
Your heart beats 100,000 times a day, every day, without rest. You’d think it needs a reliable energy source, and you’d be right. One of Amber’s references (#4) reminds me that, “Fatty acids are the heart’s main source of fuel, although ketone bodies as well as lactate can serve as fuel for heart muscle. In fact, heart muscle consumes acetoacetate in preference to glucose.”
