Yesterday was my carbup day.. and in contrast to my low-carb day I felt incredibly sluggish and sleepy today! This also had to do with lack of physical activity as Sunday is my rest day.
Yay for low-carb meals!
The reason why I still carb up is to restore glycogen levels and the high food consumption also tricks my body into believing there's no reason to hoard fat as there is no crisis (6 days/week I'm about 500-600 kcal below maintenance intake).
