Time-series data analysis of blood-sugar level of a diabetic in relationship to lifestyle events

Twelve days of time-series blood-sugar level data of a diabetic were analyzed in relationship to lifestyle events such as food ingestion, alcohol intake, and exercise. In this analysis, to exclude the influence of other lifestyle events on blood-sugar level variation, only data within time-windows where the target lifestyle event occurred, were considered. Three main results were obtained: (1) ingestion of grain or meat/fish/beans caused blood-sugar level to peak after one hour, (2) exercise decreased blood-sugar level rapidly in thirty minutes, (3) alcohol intake, particularly beer, increased blood-sugar level.
