Not sure why humans always have to drift to the extremes, high carb vs full keto. Always the extremes.
I try the middle ground, pretty much what Froome and others are doing: I periodize my carb intake depending on my training load and goals.
Base diet is LCHF-ish/protein rich, carbs are consumed to fuel workouts (depending on workout pre/during/post). There can be days with very high carb intake (8-12 g/kg).
I compete in events where both is needed, high/efficient fat oxidation and high level efforts fuelled by high octane carbs. I can get out of the door without breakfast and ride for 6 hours without any food intake. On the other hand my carb metabolism isn’t downregulated and I can use them to fuel high intensity efforts.
Best of both worlds.
