Pre Window Workout Carb Exception
Pre window workout carb exception permits a small pre-session carb-and-protein snack before the eating window opens when fasted hard training repeatedly underperforms.
Pre window workout carb exception allows a small carb-and-protein snack—banana with whey, rice cakes, or sports drink—minutes before a morning session even when the formal eating window has not opened, when fasted attempts repeatedly fail quality targets. The exception is for hard output, not habit grazing: roughly fifteen to thirty grams carbs plus ten to twenty grams protein, then break-fast as planned.
Black coffee alone does not count. Some coaches treat this as window start; others log it as training fuel only.
Common questions
-
Does a pre-workout snack break intermittent fasting?
Calories before the window technically end the fast early. Many athletes accept a small training snack when fasted quality suffers—then keep break-fast as the first full meal inside the planned window.
