Calories burned keeps changing

Sorry if this is mentioned in previous post but I gave up looking after a few pages.

At the beginning of my day my Current Cals. Burned will read 0 of 2,329 cals. I have noticed that sometimes the second number increases. Today I went in to log my foods and noticed that it happened again it now reads 2,629 of 3,068. Why does this change; it happens about once a week.

I'm seeing the same thing...I started out at ~2300, now it's at 2,507.  What's happening here?

IDK I gave up looking for an answer

Do you log activity?

0 of 2329 burned is what you should see at midnight, by the time you wake up, you should have burned some -- we burn calories 24/7/365, every breath you take, every eye you blink burns calories. 2329 is your CC BMR, based on the information you put into your account settings (age, gender, height, weight, and activity level)

2,629 of 3,068 would lead me to believe that you logged some activity, and therefore, you increased your burn potential, and at the time you logged your food, you had burned 2629 calories from midnight

Thanks coach, that's the answer.  I just looked  back at days I logged activity vs days I didn't, and that accounts for the discrepancy nicely.
