I try to buy mostly organic one ingredient foods, or close to as possible. I've also cut out white potatoes, white rice, breads, pasta, flour, and sugar. It took almost 2 weeks before my sugar/carb cravings completely went away. I do have an apple every day either with nuts or almond butter for a snack.
I eat only wild caught Alaskan salmon and seafood, along with grass-fed beef. No more farm raised seafood. I have a raw salad and a cooked vegetable with lunch and dinner along with seafood, chicken, or beef. Breakfast is eggs and veggies or oatmeal with walnuts or an organic whey protein shake.
