After working with SuperD doing DC training and reading Massive G's articles and what Dante preaches I ALWAYS eat meats/fats then carbs. In short, (from what I understand) is it takes more energy to digest the proteins than carbs thus upping the caloric expendicture of your body increasing your metabolism turning you into a furnace. You stay leaner, eat more, gain more size, and stage off fat. Either way I normally don't eat sandwhiches or anything that has the carb's/proteins mixed together. Always eat something like 99% lean ground turkey with 2 tbs of almond butter mixed into it followed by my carbs (normally oats, oat bran, potatoes, rice, etc).
Does anyone feel that they have seen this work better for them than mixing or eating carbs first, that's the question? I have always ate like this since really training and dieting hard so I have nothing else to go by.
