In response to your ketosis. One can buy ketone strips from the drug store for approx 10 dollars for 50 of them. It is best to test this when you first wake up and you will see if you are burning and how high are you burning. When you are burning ketones that is a sure sign that you are burning fats. this is what the ketosis is all about. If you start eating starches and carbs it can throw you right out of ketosis so this one has to be careful with.
Hope that helps you
