Definition
A refeed is a single day at or above maintenance — almost entirely from carbs — used during a long cut to replenish muscle glycogen, raise leptin (the satiety hormone that drops in deficits), and reset training performance. Different from a cheat day: protein stays high, fat stays low, food stays clean.
Real questions
How often should I refeed?
