If you’re performing high-intensity cardio you’re burning mainly carbohydrates and not a carb/fat fuel mix like you would be during low intensity cardio. But wait… if you’re burning carbs you’re still creating a carb/calorie deficit that will signal your body to switch and burn the carb/fat fuel mix after the workout and throughout the day. Case and point, if you want to burn fat, create a carb/calorie deficit. The fastest way (maybe not the easiest though!) is with high-intensity cardio.
