I find all of these resources extremely helpful as I am continually trying to learn about ketosis, ketogenic lifestyles, and the anatomy of the human body when it comes to eating.  I urge you to do your own research before you leap both feet first, but all of these blogs/sites helped me tremendously.  Whether it's anatomy, meal plans, before/after pics, or nutrient breakdown, you should find these helpful in mapping your own unique keto or low carb lifestyle.
