PWO cortisol levels can be any where in the 20-30 mcg/dl range (depeding on time of day and intensity). I don't see any possible way you can 'use' 100g of dextose, as with cortisol levels in that range, you won't secret insulin (not a usable amount). Consuming carbohydrates does not trigger an insulin response in that kind of an environment and secreted insulin is resisted. These are the findings of many people in the medical community. This is the basis for syndrome 'x', a possible cause of pre-diabetes, and heart disease. Mayo Clinic has many studies that show this data.
Pro's use insulin for two reasons.
* A PWO insulin injection would be necessary for proper uptake of glucose and amino's. (you can't secrete enough of it.) (this is of course if you can lower HR enough to efficiently digest)
* Elevated hgh suppresses Insulin activity
So, if you are consuming a PWO birthday cake shake without injecting insulin.... not only will your insulin not be capable of working properly, but the presence of glucocorticoids like cortisol tell insulin to STORE FAT. This is assuming, of course, you manage to actually 'digest' some of that PWO shake. Cortisol and CRH halt digestion... and the elevated cardiac flow wouldn't allow for even "decent" nutrient uptake through micro villi.
Why do so many people have this illogical habit and why do they defend it to their death?
Oh, and by the way...... Here is the trump card. If consuming carbohydrates triggered a usable insulin response in the presence of elevated cortisol; there would be no such thing as "Cushing's Syndrome"
