but would it break down muscle tissue? My performance is fine, desu- I can run/pedal at the same speed.

There is 2 reasons why your body breaks down muscle.
1. You do not have have any free amino acids in your system or useless protein that your body can salvage right now.
2. Your body requires an alternate energy source because your carbohydrate levels are depleted, but your current insulin levels are too high to dig into your fat reserve. (This happens when you calorie restrict while eating frequent meals).

>tl;dr no, morning fasted cardio won't cause you to lose muscle, it will actually help with fat loss.
