Should I do Interval training on empty stomach?

I drink water or iced tea before I run or bike in the morning to avoid dehydration. Breakfast comes after the workout.

thanks for the reply, my only concern is muscle loss, but if I thought If I ate protein right after it shouldn't be a problem right?

Wrong.

It's what your body needs as energy source at the time of the workout, not what it got later.

So you fasted all night basically, your liver glucose stores are almost tapped out.

You go do a glucose intensive workout.

Now, the muscles have glucose in them for what the muscles need, that's fine and great. But that can't be put into the blood stream, only the local muscles.

So the liver is finished off, blood sugar drops, there is no more available glucose to put in to help, so something is going to be used. Some of the lactic acid from your intense carb-burning workout will be used, but sadly that is slow and inefficient, or else you would never feel the burn.

The next most efficient thing to break down is muscle. To the tune of 600 cal in a lb when used that way.
Now, this at least is not for general use, only the blood sugar, used for brain and heart and other organs that have no glucose storage. So it's not much, but it is some.

I lost 3.2 lbs of muscle that way over 6 weeks with specific spin bike one night followed next day with intense run, and never topping off carbs enough, same situation.

Buy some Clif Bars that have 40 carbs to 10 protein about, and eat as soon as you wake up with water. It should be digested enough by the time you get to the gym.

You eating protein afterwards won't matter, it'll be used to repair the muscle you actually used, not what was torn down for glucose.
You won't make that back while eating at good deficit, not working it out heavily, and you don't even know what was broken down.

And while it only supplies 600 calories of energy, it takes more than 3500 to build it, and lucky to get 2 lbs a month when doing things properly.

I don't suggest it.

What kind of intervals do you think you are going to do every morning? Only 20% of your cardio time should be spent on intervals, or you really don't get out of what you are putting into it.

If this is for the purpose of fat burning, actually do that which works better, even while fasted. Weight lifting.
Upper one morning, lower the next. Repeat.

so you would suggest weight training on empty stomach instead?

Yes.

Doesn't burn nearly the number of carb calories during the session, but burns fat later through the day during repair, after you've given it that great high protein breakfast, which will be used during repair of muscles.

It's incredible the number of posters that didn't actually read your post nor intent nor plans.

I took interval training to be cardio.

I do the bodyrock.tv interval training workouts which are short but quite intense.

Have a look on youtube for zuzanna light who was the original body rock girl.

She has posted some vidz on eating right for training before and after

cheers
