Specifically, I begin to experience edginess, palpitations, and a general "fight or flight" feeling. Since these symptoms are reminiscent of hypoglycemia I conjecture that my liver is not as efficient at gluconeogenesis as it should be. The body uses stress hormones, such as cortisol, to signal the liver to crank out glucose. My theory is that the stress hormones are causing the fight-or-flight symptoms. Further support for this conjecture is the fact that I only experience this at very low carb intake levels: 20g/day or so. Todd Moody [log in to unmask]
