I have but the book mentioned in that article is essentially snake oil. I had been changing my eating habits to achieve fitness goals for some time now. Basically, a multi vitamin/mineral supplement (I recommend Twinlab dual tabs), fish oil supplement, abstaining from refined sugars/processed foods, a diet of whole foods (brown rice, quinoa, oatmeal, beans, lintils, vegatables, fresh fruit, nuts, honey, seeds, spinach, coconut oil, ginger, egg whites, chicken, some steak, etc), and limiting caffeine intake to ~50mg per day or less.

If you want something more specific Google "Zero Willpower Eating System". The only part of that eating system I'd recommend someone with bipolar change is adding fats from stir frying with coconut oil, nuts to oatmeal or as a snack - basically have ~25% of calories be from fats which are good, calculate your protein requirements based upon your level of physical activity and bmi, then fill the rest with complex carbohydrates and fresh fruits.

Also foods high in gluten spike insulin and can adversely affect overall mood - pasta, enriched flour, bagels, bread, etc.
