As was mentioned in the OP:
Neither of you need to worry about your increased fasting glucose. Once you have been fat adapted for many months your muscles and other tissues, that do not require glucose but which can use ketones or fatty acids for energy, will preferentially take those over glucose in order to leave the glucose for the tissues that must have it like the red blood cells and certain cells of your brain. This effect, is commonly referred to as ‘glucose sparing’ or ‘physiological insulin resistance’. Do not be fooled by that scary sounding latter term. It is differentiated from ‘pathological insulin resistance’ and is a good thing. Basically, with fat adaptation, your muscle cells become insulin-resistant so that they resist pulling in glucose thus leaving glucose at a higher levels circulating in your blood and leading to higher fasting glucose. This good effect however is easily undone with only a few days of poor eating choices.
