It's wrong to lump common sense advise together with the previously-scientific-until-proven-otherwise low-fat diets. Common sense here, in my opinion, should refer to what has been generationally observed. Even if there's mistakes in there, our bodies would have evolved to handle them well. It's when we try to substitute what has been a generational practice with careful study that we go wrong. Because careful study is not careful enough, and often makes the common mistake of prescribing new things, food, actions, processes, etc.
