Dear Mark: High HbA1c with Low Blood Sugar; Muscle Glycogen: Is It Local?; and Ketogenic Mosquito Repellant
For today’s edition of Dear Mark, we’ve got a three-parter. First, what could possibly explain an ardent and otherwise healthy low-carber with stellar postprandial (i.e. after a meal) blood sugar levels showing up with an HbA1c reading indicative of pre-diabetes? Who’s messing up — the test or Nancy herself? Next, that pastured chicken you’re about to eat may very well be local, but what about the glycogen in your quads? Is a muscle’s glycogen usable only by that muscle, or can it be shipped to nearby muscles as well? And finally, a reader reports suddenly becoming unattractive to mosquitoes upon adopting a low-carb diet and bouncing in and out of ketosis. Is he imagining things or is there a potential mechanism at play?
