Everyone is talking about "empty stomach" cardio — is this the best way to burn fat?

I don't believe everyone is talking about empty stomach cardio ... perhaps just the people where you are "hanging out." Cardio is fine at any point in time, and it is more what you burn and take in throughout the day than the exact time that matters. In fact, some will argue that empty stomach cardio does not in fact burn more fat, but rather takes on some muscle mass as well.
