Are you suggesting that you cannot lose weight while staying calm? I don't see what 'staying calm' has anything to do with this. And i'm not talking solely about losing weight but losing weight and holding on to muscle.
I think you need to consider the roles of each of those molecules.
Insulin is all about packaging. Wether it's pulling glucose (with or without an amino acid) into a cell, H2o sol. vitamins ect.
-Insulin doesn't package anything, its stimulates adipose/muscle to store carbs/fats/proteins/vitamins etc. As well, as far as i know, it antagonizes cortisol (which is why sugar is used post w/o to stop the cortisol secretion, its not the glucose itself but the insulin which antagonizes cortisol)
Diet, is all about efficiency. The idea is to package everything in a manner that you see best fit.
-I don't know what the hell you are even talking about here
Besides, the cortisol without the insulin... just leaves you breaking down tissue into a macromolecule without anything to package it! Catch 22 or whatever they call that shit.
-Check out my comment up top, i don't think cortisol and insulin play very well together as cortisol is about catabolism and insulin is about synthesis and anabolism
Think about a diabetic getting his bg under control. He is going to LOSE his gut.
-this depends on too many factors to get into, not all diabetics lose their gut
It would completely depend on the individual and his or her diet (and ethnicity)
A Russian wouldn't be able to imagine a Chinese male of the same size getting drunk so fast.... unless he understood the role of alcohol dehydrogenase. We may all be Human. But none of us are the same. Period.
-Yes i'm aware of this. Bringing up a lack of an enzyme is a bit misleading to the newbs around here. We all have insulin, cortisol, stress and glucose. Apples and oranges IMO
