Since Taubes GCBC, we have know that getting fat is the body's response to the SAD. Now is that getting into the researchers sights?
One of the solutions is to drift toward some form of Paleo, Paleo template, real food diet. That by it's self may not be enough, some form of mental clearing of the built up bull shit piled on by media, medical disinformation, misdirection, may also be required. Dispelling all the collective super-ego concepts is also helpful. Those are the ideas and concepts that guide us, imposed by society that knows less than I do about food and the issues overeating, obesity, and related similar subjects.
