Training/breakfast help! Am I sabotaging myself?

Hey everybody, so I recently got a morning job and decided to get my workouts done before I head off to work. Now here's the problem, I've heard that cardio before eating burns fat great, but skipping breakfast is awful. Yet nobody seems to answer AT WHAT POINT IS BREAKFAST NOT BREAKFAST??!

Quick reference, I am 5'7, weighed around 137 before I switched to this regiment, but now am gaining...muscle I hope (started more weights)

I wake up at around 6:50, have some coffee/check email, then hit the gym from 7:45-8:15, or about 300 cal worth of cardio in the 80% heart rate range. Come home, shower, do a few pull ups/push ups, then bike to work (another half hour, prob around same calorie amount)

By now its 10 am and I am finally having my "breakfast" of a protein shake blended with eggs, flax, and berries with some almonds in the office.

So heres my question: Am I destroying my metabolism or will this morning workout help me shed more fat? Im going for a lean body and ideally want to just cut my body fat percentage, though Im scared I might be hurting my metabolism more than burning fat in the morning. Advice please?
Thanks in advance!

Everyone is different in terms of how quickly their body will catabolize muscle tissue for fuel in the absence of food, as well as the extent to which it will catabollize muscle in the absence of food. Therefore, the only way to tell if you're burning muscle for fuel is to track your fat loss and lean body weight each week. It's all in the numbers.

If you lose, say 1% of your body weight each week, you can figure out if it was fat or muscle by tracking your body composition with skinfold calipers, and comparing it to the previous week. Presto--there's your answer! ) I'll see if I can dig up the formula for you . . .

Here's a no-math, super convenient way to figure it out each week:

Good luck!

Eat before you hit the gym.Protein and carbs so you dont burn muscle.Also you need energy to push weights.Take a scoop of protein before cardio(30min.before).You either are cutting or bulking...cant do both.So if you want to just cut more fat off,eat less.But if you want muscle,then eat more.
