I'm also going to begin checking my ketone levels. According to the authors of The Art and Science of Low Carbohydrate Performance, I need to be between .5 and 3 ketones to be in nutritional ketosis. Here's the recommended graph from the book..
The problem is that the ketone test strips are expensive! About $5 a strip! I think I'll do my first check in a couple days, it may take that long to become keto adapted. I'm strictly following LCHF, keeping my carbs below 50g and my protein around 60g.
This morning my glucose reading was 79, down from yesterday.
