Purpose of Cardio

[gu3mute]

I have hear people say they do cardio to get cut, and to help keep fat off while bulking. What I am wondering though, is if this is true. I don't quite understand how it would be helpful in losing fat. It seems to me that if you are eating a certain amount of food and doing cardio, you could achieve the same effect by just eating less and not even doing the cardio.
I hope you understand what I'm asking I can't seem to word it how I want.

Why do cardio when you can just eat less?
Thanks

Don't quote me on this, but I've read somewhere that dieting by JUST reducing calories will result in more lean muscle loss than reducing calories AND using cardio.

Plus, there's this thing called your heart. . . and cardiovascular health is important while bulking, helps you work harder in the gym, etc.

You don't have to. You are 100% right.

Some people do cardio exercises for the health benefits.

More favorable nutrient/substrate use.

more oxegen into your bloodstream = more muscle (bulking)
calories in calories out (cutting)

and yes you can cut without cardio

If I am about to start 5x5, how many times a week should I do cardio? HIIT, but how long?

Whatever you like. Just don't go crazy and run yourself into the ground with it.

Okay. I don't do any cardio as is so if it helps with bulking, then I'll start it up and keep my calories the same cause I need to shed some BF.
