Good points, but I would just add once I ate almost nothing but salad and salmon or sardines for two weeks and it completely transfigured my physiology in a way that continues to astound me. As a result of that my primary recommendation is that people experiment with the best diet plans they can find and try them in two week blocks to let changes set in.
