I originally asked this on the Crossfit nutrition forum but didn't get any responses there.
I can't reconcile this. In Nutrient Timing, Dr. Ivy basically argues that it's ideal to raise your blood sugar level just at the end of a workout, because your muscles are more receptive to glycogen intake during that window, which closes quickly (like within half an hour of the end of the workout). Also you need insulin to build muscle, so increasing your insulin window during this time means your muscles will regenerate more effectively during the recovery and eating period to follow. This all seems
to make sense.
On the other hand, in Protein Power, Eades/Eades argue that the critical component in muscular development is HGH (human growth hormone, generally recognized as very good stuff), and that the release of HGH is attenuated in the face of high blood sugar. Therefore you shouldn't eat any carbohydrate before, during, or after your workout. You should just have a high protein/fat meal an hour after lifting because HGH will be manufactured if you keep your blood sugar low.
OK so what am I missing? If one of them is wrong then which one? If they're both right then which negative (or positive) factor is dominating?
