I would say that high octane means high nutrient density regardless of the energy density. I consider leafy greens to be 'high octane' and they're low density. I also consider avocado to be 'high octane' and it's quite energy dense.
One thing that should be made clear is even though I tend to err on the lower-carb side of things, I'll make the caveat that you have to eat a necessary load of carbs for the work you have planned. If you're riding a crit or doing anaerobic intervals, you better be carb'd up or else you'll be flat as a fart.
