Does eating zero (or almost zero) carbs per day provide benefits over eating 20 carbs per day? At the moment I'm consuming a lot of protein powder and my total carbs per day is usually around 20 grams. If I were to switch to a zero/low carb protein powder, I could cut my daily carb consumed to 6 or lower. Is there any benefit in going from 20 carbs to day to 6 or less or even zero?
