Re: Misogi - The diet part
I think it's been established (and it's definitely common sense) that elaborate diets such as the so-called Paleo diet, work well in the short term because, with their intense focus on the minutia of diet, they make people very much aware of eating. When you're paying close attention to eating, you're less likely to overeat, more likely to eat regularly, etc. That change alone encourages a tendency towards healthier weight and better health overall. Unfortunately, elaborate diets tend not to work long term because most people can't follow them for very long (although there are exceptions -- my boss is one).
