It all depends on how active you are, your diet and what time of the day. However everyone is different. Your BG reading could be 60, and mine could be 80, but we could both be feeling the same. So what you have to do is, check your BG levels and see how you feel on certain levels. Once you know how you feel on certain levels, next time you check your BG, you will be able to tell how far away you are from hypo or hyper and know around what level your body needs the nutrients to keep out of hypo. I use my BG monitor as a guideline.
