I realize this post is 14 months old, but I’ve been eating ketogenically and running and biking for 6 weeks straight. I rarely measure any ketones with my blood meter. I don’t measure daily, but do measure at least 4x/week. Usually first thing in the morning I don’t register any. Before bed, I’d say the highest I am will be 0.4. I once measured 1.1 during my first week on the diet. ONCE. I’ve been an endurance athlete for 12 years and perhaps I was able to adapt quickly and my body just doesn’t produce much in excess? At least two of my female endurance friends have this same issue.
My blood glucose levels are pretty consistently at upper 70’s to low 80’s.
