Blood Sugar Graph (Negative Feedback Loop)

Blood Sugar
After the ingestion of a carbohydrate rich meal, blood glucose levels increase rapidly. Once the body detects these elevated blood glucose levels it releases insulin. Blood glucose levels peak and then fall off and insulin does the same, however insulin levels peak later than blood glucose. Once blood glucose levels reach normal again, it takes insulin a little bit longer to reach normal again. It is this lag time in normalization of insulin levels which gives us those sugar cravings after carbohydrate rich meals.
