When you are on hi carb diet, our body utilize carb as energy.
When you are on hi fat low carb diet, fat is used as primary source of energy.
We have unlimited source of energy from fat. That is good enuf to prevent muscle loss. Doing cardio early in the morning on empty stomach actually uses more fat as energy regardless you're on hi carb or low carb.

You'll be surprised that you can actually perform better on empty stomach early in the morning than after food. Since it is only 12 minutes, how much of muscles can you lose? You ain't running a full marathon, there's no need to worry about muscle loss.

BTW what the heck is HIIT?

It should be

"It's not the quantity of the weight, but quality of the movement"
