“I’ve read the theory that our bodies don’t recognize these artificially grown and developed items as “food.”  (Doritos, though delicious, are not picked from a Dorito bush.)  Because of that, our bodies are always in search of nutrients, which makes us hungrier.  We eat and eat, yet never feel satisfied.  So:  our portions are bigger, we eat out more, we reach for convenience foods, and our food supply has changed.  Our hunger hormones are on overdrive because we have tried (unsuccessfully) to restrict what we are eating and we are eating processed junk.”
