I recently discovered atomic Iodine. I really like this! I feel balanced, less hunger and a little more energy. "Nascent Iodine"

Exercise is so key, walking a lot helps.  Depending on your genotype, increasing fats in your diet may help.  Eating more butter has helped me a lot.

Getting rid of just wheat was not enough for me.  I had to be sure I wasn't eating a single smidge of gluten to get back my energy.  The website celiac.com helped me research what products might have gluten...one of the last products to go was any spice I couldn't comfirm gluten free as they sometimes use wheat products to keep the spice from sticking together in clumps.  Dairy works similar for me...if I eat ice cream I actually get sleepy.  

Some of my favorite feel good foods are beef, cod, greens, broccoli, onions, artichokes, and bananas. Oh, and green tea.  Since it has gotten warmer I don't drink hot tea and never realized my body was missing it until I had a cup the other day and "oh yeah, my body likes this stuff".  So I started making some cold green tea to drink during or after my walks.

A green smoothie for breakfast most days, i.e., one or two fruits, two or three green leaf vegetables--all from my diamond superfoods list--some ginger, lemon juice, compliant protein nuts/seeds/oil and larch powder, all mixed together in the Vita-Mix, seems to burn very cleanly and for over the over the span of a few hours. During this time my energy does not flag, but neither is it a nervous-type energy ... and then I eat lunch. (:

Hope this helps and, like Sahara mentioned, consistent exercise is such an important component. The more you work the body's muscles, the better the other positive things you're doing related to nutrition fall into place.
