I have no doubt that you do, but I am equally as sure that you are misunderstanding the term "catabolic" and the role of Cortisol. As I said previously, Cortisol's role as a catabolic catalyst is to provide the system energy from the destructive metabolism of more complex energy units. Catabolism is a necessary condition for performance and lean tissue growth in regards to lean tissue proliferation [in resistance training]. Without catabolic processes [such as glycolysis, citric acid cycle and lipolysis] our bodies would have no fuel during exercise.
Again, Cortisol's role in respects to resistance training is not to catalyze a destructive metabolism of lean tissue, but rather to promote oxidative metabolism of fatty acids and triglycerides, maintain glucose homeostasis [via regulation of Glucagon and Insulin], and regulate epinephrine or norepinephrine serum levels. Cortisol is completely necessary in a resistance training environment, and really only plays a negative aesthetic role when it is elevated post-training. Lower Cortisol levels may actually impede fasted training.
I.e., lower Cortisol did not impact performance, and may have hindered it. Further, as I have stated, lean tissue is not the primary oxidative substrate target for Cortisol during exercise.
Actually, Cortisol will decrease plasma glucose levels during exercise. While the inverse is true in rest conditions, we are speaking about training! However, you are correct on the first points - all benefits to a fasted training environment.
Also, RR, please give proper reference when quoting verbatim! Your commentary was found here, I believe:

Again, I disagree and feel you are misrepresenting the role of Cortisol, specifically in regards to its necessary role in resistance training. We must be weary of elevated Cortisol in the proceeding 130-150 min period after training, not before. Suppressing pre-exercise Cortisol would negatively impact Fasted Training. However, the addition of intra-workout BCAAs and utilizing ReCreate as a selective 11B-HSD1 inhibitor are added for just this purpose.
Again, please reference when using direct quotes, RR. I know this was not your intention, but it makes it appear as if you are representing this as original thought!
Again, these are rest-state specific changes.
Again, I disagree. We must also take into account a more accurate and direct description of what we mean by elevated. This can be mean elevated from circadian baselines, or it can mean exercise-induced intra-workout elevation from acute stress factors. However, at any rate, normal circadian release of Cortisol will not negatively affect fasted training in any way, but its suppression may.
Yes it was from wikipedia, as translating the articles from russian to english is painstaking.
Sorry, i never meant for the terms i used to sound like my own words, i quoted so as to show it wasnt my thoughts but proven fact.
I still disagree with aspects of your advice, i assertain that dosing aminos before fasted training, would be beneficial and prove to help the burning of fat during exercise, while diminishing the oppurtunity for a catabolic stress hormone to wreck havoc upon muscle tissue.
I do believe that once the body has adjusted to fasted training, then muscle will not be used to fuel exercise, but rather fat and glycogen, but even then i would rather take preventative measures, than throw caution to the wind as it were, Even though as you said..I.e., lower Cortisol did not impact performance, and may have hindered it. Further, as I have stated, lean tissue is not the primary oxidative substrate target for Cortisol during exercise.
And yes i again agree with you that the time post training, is extremely important to negate the effects of cortisol, as at this time it can have a direct affect upon muscle tissue..or lean tissues.
I personaly though will continue to use a full spectrum amino supplement before fasted training, as i find it higly beneficial in retaining muscle and at th same time allowing me to push harder through the pain barrier, utilizing more fat calories.
Just to reiterate, i am not saying you are wrong, but i do have different ideas based on my own findings, and on the studies i conducted in university.
FOR EXAMPLE...
Conversely, cAMP can indeed be preserved by methylxanthines in coffee and tea, as they interfere with a cAMP destroyer called phosphodiesterase. So why aren't heavy coffee/tea drinkers all extremely lean? Because much of the fat that's broken down and mobilized circulates throughout the bloodstream of a sedentary person and eventually gets re-esterified or rebuilt into stored fat. It doesn't get taken up by contracting skeletal muscle and burned on its trip through the blood. So just mobilising fat when in a fasted state doesnt mean they leave the body..
This is from robert lowery explaing cAMP.
Cyclic AMP is a signal to break things down within a cell such as glycogen (stored carbohydrate in muscle tissue) and yes, triacylglycerols (stored fat in muscle and fat tissue). So in weight loss situations, well-timed lower insulin concentrations can be helpful.
My view here is that whenever you are completely fasted, or protein starved..it doesnt sound good does it, your body breaks down muscle to some degree, not good when trying to preserve muscle while loosing weight, or vicerol fat, do you want to be a runner, or a bodybuilder?
So here just to keep things safe, the added aminos, 5-10 grams would stop cortisol using the aminos in your muscles for fuel..in other words breaking down muscle.
... or maybe :think: it is just placebo ! :lol:
