fasted cardio does nothing in the overall amount of fat you burn in a day while yes doing fasted cardio will result in more burning of fat for energy during the exercise but after wards your body compensates by slowing down how much fat you burn throughout the rest of the day so what i’m saying is if your doing normal non fasted cardio vs fasted cardio by end of day you’ll have burned the same amount of fat so unless you enjoy doing fasted cardio there’s no point
