im going to try it in the moring and after workout to see what works best.
the only way to see what works best for you...do it in the morning for one show over 12 weeks, and then the next time you get in shape try it after training.
combining both, you'll never know what is working.
Here you go...To use fats as a form of energy, you need to produce OAA (oxaloacetate). Fat ultiziation is dependant on OAA, and OAA can only be produced from carbohydrates and certain amino acids.
So, yes if you do fasted cardio in the morning you will use fat as fuel because of the lower glucose levels after not eating for 5-8 hours, BUT in doing so your body will have to break down protein to make OAA. In the end, its your choice, but fasted cardio most definitely will cause proteolysis.
I would not recommend fasted cardio.
why would it cause proteolysis, you already said it uses carbs or aminos let me quote something that i found interesting:
Oxaloacetate is both a gluconeogenesis and Krebs cycle intermediary. When the liver needs to synthesize glucose, it pulls oxaloacetate out of the Krebs cycle, resulting in increased hepatic acetyl-CoA. This buildup of acetyl-CoA triggers the production of ketone bodies. All of this occurs in the liver: non-hepatic cells are still using their oxaloacetate in their Krebs cycle, in addition to generating acetyl-CoA directly from ketone bodies.
Oxaloacetate can be produced from glucose via pyruvate, and glucogenic (which is most) amino acids are metabolized into various Krebs cycle intermediaries, which either are or can be turned into oxaloacetate.
even if you do cardio after your workout the glycogen in your liver will be low, so no matter how you look at it you'll be converting sugars or aminos to oxidate fat. not recommending a type of cardio just because there's this fear of losing muscle mass is just silly.
I am walking towards dead end. I am walking all alone.

then all the carido shouldn´t be fasted? either in the morning or after the workout? slow always?

since i started doing it in the am ill stick to am cardio then. thanks bro.

then it doesnt matter if i do it fasted right man?

that is the exact reason why i would recommend doing HIIT training postworkout for a couple reasons.
1. You LIMIT amino acid breakdown. i am not saying that you can stop this 100%, but the goal is to limit it as much as possible. And if you do fasted morning cardio, amino acid breakdown is the only way to produce OAA and burn fat.
2. When doing HIIT postworkout you will be able to use up rest of your creatine phosphate and glycogen stores in the immediate system and glycolysis, and then during rest after your cardio you will use Krebs cycle and the Electron Transport Chain and use fat as fuel.
I am just saying that if you don't want to use amino acids as your fuel for burning fat (which i would assume that you wouldn't), it would not be wise to do morning fasted cardio.

then slow cardio in the AM and HIIT after the workout right?

yeah if you are really wanting to do morning fasted cardio, it definitely needs to be low intensity

as is the case usually, it depends on the individuals metabolism and his/her goals- find out what works for you. fasted cardio is a proven way to drop pounds, especially adding in Cuts or an EC stack (with aspirin or WWB)- just remember if fasted, do LISS, and get some carbs in you if your going to do HIT
in the end, i believe just getting your cardio in, whether it's after your workout, fasted am cardio, before you go to bed etc...., is going to be more crucial than any of the particulars
