There are lots of other advantages to being on a low-carb health fat diet.

I mentioned the issue before about not having to refuel constantly, so you don't have to keep chugging down drinks and gels and so on when you're on a long run.
I think also you recover a lot better. It's probably related to this inflammation factor. That soreness you get after exercise is significantly reduced when you reduce those foods that cause inflammation.
