I have been asked this question a few times. What’s the best way to start a whole foods based approach to nutrition. The best idea that I have seen was recommended in the Engine 2 diet book.
First week, try to get breakfast right. Second week, try to get lunch right. Third week, start working on the dinners.
So for breakfast, why not try 1-2 cups of oatmeal, 1/2 of berries, 2 bananas and 1/2 cup of soy or almond milk. If you want to get fancy, add 2 Tbsp of ground flax meal and some cinnamon to your oatmeal. Done! You are now on your way.
