People, don´t forget that comparing bodies within a given population, metabolism and response to training and nutrition can be partly described as a stochastic! In my mind, clean foods are only those that cultivated without growth hormones and other chemicals, are not deep fired and overall contain less saturated. People who take in the majority of their nutrients from "Clean" take in less because of the absence of saturated fats. Clean food does nothing for your metabolism per se, it is the LACK of chemicals and fat which is the "healthi-ness" of clean foods. I see a LOT of overweight people with shopping wagons FULL of "Clean Foods".
