Is Fasted Morning Cardio Superior?
Q: I believe you’re a fan of cardio in the A.M. As a person who hates mornings, is morning cardio necessary or is it acceptable to do evening cardio when prepping? Also, do you prefer fasted cardio or getting some food in first? Shelby: Ah yes, the good old fasted cardio debate. I have always done my cardio in the morning on an empty stomach, and when the amount gets really high (over an hour), I’ll start adding in P.M. sessions, either directly after weights if it’s a training day, or just in the evening if it’s a rest day. The argument for A.M fasted cardio is that in the morning, after an overnight fast, your body is slightly glycogen depleted and insulin levels are low, so fat will be the primary fuel source for cardio (at least for low to moderate intensity cardio). The argument for “anytime” cardio is that the aforementioned variables don’t really matter; fat loss is simply a matter of calories in vs. calories out, and doing cardio later in the day will produce the same results g
