Cardio Workout: On a Full or Empty Stomach?

Cardio workout is necessary if you want to burn fat.

What is best? Cardio on an empty stomach (fasted) or cardio on a full stomach (fed)?

I found a fellow on YouTube explaning what is best. He categorizes the conversation into:

• What is your goal?
• Hormones 
• Insulin 
• Grow hormones, 
• Catacolines
• Intensity
• Glycogen (stored energy in our muscles) and energy
• Strategy

In the video he talks about a link; if you want to use his link find the link below his video on this link .
