Final answer:
The lowest blood glucose levels during a typical day of eating are checked during the fasting or post-absorptive state.
Step-by-step explanation:
During a typical day of eating, the lowest blood glucose levels are checked during the fasting or post-absorptive state, which occurs when the food has been digested, absorbed, and stored. In this state, the body relies initially on stored glycogen, and as glucose is absorbed and used by the cells, blood glucose levels begin to drop.
Insulin levels also drop in response to the decrease in glucose. Blood glucose levels during the fasting state are typically in the normal range of 80-120 mg/dL.
