Yeah the sleepiness usually comes from carbs; if I take fibers/protein it feels better. Maybe anectodal but still, even if I'm physically active the whole day

Yeah the sleepiness usually comes from carbs; if I take fibers/protein it feels better. Maybe anectodal but still, even if I'm physically active the whole day (unless I'm snowboarding with a tshirt 9-17) I really feel better off eating nothing. I feel the urge to eat after physical activity, but not before. If I eat (and I'm not planning to burn 2000+ active calories) I'm still better off on not having any breakfast but just water and perform MUCH better on physical/mental activities.
