I don't know what's wrong with you 80-10-10 people. The human brain is 60% fat so you might want to think about eating some soon. You said he was 40-30-30, not me. There's absolutely no way you can tell. You have no clue what quantities of anything he eats. I'd bet he's running in the 10-30% range. It's extremely difficult to get to 40% carbs when your not eating breads, pastas, grains, starches, legumes, etc. Even the SAD only runs at 50% carbs with all the breads and pastas and pizzas and potatoes and corn syrup and sugar and pastry and bagels that everyone consumes.
I read what you wrote, you just hallucinated that I didn't. Oh, and let me quote specifically what you asked because you clearly can't remember "Where are all the elite Paleo runners and cyclists?"
By the way, there are recent studies that are showing that coconut oil reverses dimentia and alzheimer's symptoms, in case it's needed.
