Hi! there is a book called Keto Clarity (released like 3-4 months ago) write by this guy Jimmy Moore. I'm actually reading it.
its very good at explaining all the aproaches on the low-carbs ketogenic diets, and what are all the factors that contributes to this keto-state.
roughly speaking, it propose a low-carb, moderate protein, and high-fat diet, to make the switch to burn fat on the body.
measuring the ketones on the blood is an important part of the diet, cause you have to find your own proportions for carb-fat-protein, that will make you to burn fat and produce ketones.
its good book, I was personally really confused about all the things that are being said about the LC and ketosis and so.. and this is being really clarifying.
I recommend to the ones that are too confused about this subject!
