Had slices 7 & 8 of the pizza last night, along with about 7 oz of hamburger. Woke up this morning and blew a 6.1 on the meter.

Lifted about 22,000 lbs with free weights for about 75 minutes. It was 1.1 about halfway through the workout, and 0.5 when I was done. This was with nothing to eat since dinner last night.

Why would my ketone levels go down after exercising on an empty stomach?
