I don't know about raw foods, but if you want energy, you have to put some time and thought into food preparation using whole foods.
I am low on energy, too, and being pregnant I hate to spend too much time cooking. But here is an easy, healthy meal that I make often, and that leaves me feeling very good (no gas, heartburn, overfull feeling, etc...)
1. Fish- take 4-6 defrosted or fresh fish fillets (I use salmon or tilapia) and marinade in whatever you like for a few hours. I use a mixture of soy sauce, honey, vinegar, diced garlic, and orange juice. On a non-stick pan over med-med-high heat I cook until flaky. I top with diced fruit or veg like peaches, nectarines, or tomatoes.
2. Sweet potatoes- so easy to make. Peel and cube the sweet potatoes, place in non-stick pan, pour olive oil over them till they are coated but not swimming in oil. Sprinkle with sea salt and bake for 25-40 minutes at 400 degrees depending on how firm you like them (stir with spatula a few times so they brown evenly). Add rosemary leaves during last 5 minutes of cooking.
3. Wilted spinach- Cooked or wilted is healthier than raw because you can use more of the nutrients. Place 1/2 cup of water and 1-2 TB of olive oil in non-stick pan and heat till boiling. Take off heat and add several handfuls (it will wilt and get a lot smaller) of fresh baby or regular spinach (regular will take longer to wilt and you should remove the stems). Watch as it wilts so that it stays nice and green, stir with tongs if you like. When it's nice and soft, drain the water and oil, season with salt, and if you like, top with pine nuts or almonds.
This sounds like a lot of work, but it's not. It's a very easy meal that I fix often because it's healthy and easy to shop for. You don't need to spend a lot of money on processed or frozen foods. I am always full of energy after eating like this. If you don't like fish, substitute chicken breast, tofu, etc.
