I think at the end of the day the main thing when cutting is that one does some form of cardio during the day , as it further enlarges ones calorie deficit while still allowing optimal nutrition
I do fasted cardio 45 min in the morning , no food for at least 10 hours , it's also slow steady cardio heart rate 120 to 135 bpm
I then follow that up with a whey shake and oats (no fats as far as possible) but I wait 30 to 40 min post cardio to have this meal , this advice I read from Chris aceto ( trained the likes of jay cutler , mike francious etc)
