Does anyone have any suggestions on where to get nutrition help? I try to follow all the rules for endurance nutrition - about 70% of calories from carbs, a serving of solid protein with each meal, Power Bar or something similar at regular intervals during a long ride or run, recharging carbs within 30 minutes or so after a long ride or run, etc. I still bonk occasionally during or after a long ride/run without much rhyme or reason.

I've been testing for diabetes and my fasting glucose was fine, and the four-hour glucose tolerance test went o.k., too, although my levels were at the lower end of normal. I went to a dietitian awhile back and she said my diet is fine. She recommended a good sports nutrition book (Nancy Clark's Sports Nutrition Guidebook, which has lots of good information), and she also made some recommendations on good carbs/bad carbs, regular solid protein, etc. My weight doesn't fluctuate much, so I assume I'm eating enough.

Does anyone else fight sugar battles and bonks?
