With a 1.1 BHB, you should be relatively adapted. Exercise can trigger the release of both BHB and glucose. It is common for diabetics to see their glucose increase with exercise (however if they exercise and then eat, they can handle more carbs many times.). Also, though the glucose meter reads down to 1 mg/dL, it may be +/- a fair amount - they all are. With one experiment, I had two meters and a continuous glucose meter - actually the CGM read the sensor and also has strips they give very different readings.
