When I am running my long distances I also need some extra carbs so I use a non-food like GU or Accel Gel. Neither one causes me to crave anything, I don't want *more* of either, and they both satisfy the need for a quick burst of energy with a sustained carb-up for the extra miles. I would think Hammer Gel would work the same way -(often sold at biking stores). In the past I've had luck with the Extreme Beans by Jelly Belly too.

I get what you are saying for sure though. When I first joined up on the low carb WOL people would say if I didn't eat all the carbs maybe I wouldn't hit a wall. Yes, I still hit it. Or, maybe some nuts and berries along the way - not practical.
