I was thinking ( I know, dangerous!) if I low carb all day say on a Friday and then after the depletion workout, switch to the carb up, will there be a fat spill over from the morning and afternoon foods of low carb? After all, the meals are high in fat - Or....does it suit us best to not eat 3 hours or so before the depletion to ensure that the fat inside the stomach does not mix in with the carbs when venturing into the carb up phase? Make sense?
