Today my ketone reading was .6. I'm dangerously close to being kicked out of Ketosis City.
Although most of the low number is due to my endless sampling, I also took the reading earlier in the day. I usually take the reading around 3pm. Today it was at noon. If I ever get a good stash of ketone sticks, I may take a sample in the am, afternoon and evening. I can only afford to do this once, plus I don't want to stick my finger all day.
Tomorrow my husband and I have a long hike planned. I may take a reading as soon as we're done, to see if my ketones go up after exercise. I did take samples after my marathons last month. I didn't see a significant change.
On a related note, my underwear is getting baggy. Nutritional ketosis rocks!
