Oh cool, well if you have had no junk food since you were 17 you must be a fellow Atkinser!!
I only eat whole grain carb sources, my ratio is 55/25/20 of a carb/pro/fat index keyed to my body weight and activity level. I could consider altering the ratio for a specific training strategy. I am willing to change! My fats are from legumes and olive oils, am I wrong?
