Even if you eat no carbs, your glycogen stores will gradually be
replenished with glucose from gluconeogenesis. If we think of glycogen
as a fuel for suddens but not too frequent bursts of explosive effort,
that should be adequate. But, as others have pointed out, daily
high-intensity workouts to the brink of exhaustion are something else
again. For that you'd need some incoming carbohydrate.
