Since then - to help train at higher intensities and fuel longer/faster rides - I've added small doses of carbs/grains even limited fruit here or there. I gained 10#'s, and am not much faster on the bike - if at all. If anything, I'm slower uphill.

I always had reactive hypoglycemia - since my mid 20's, even as a very fit cyclists/weight lifter. For my body - carbs, grains, fruits... always = poison.

For some of us fiber/carbs are not only not essential, they are harmful.

Everyone is different. Everyone has different genetics.
