Abstract
A continuous glucose monitoring (CGM) system was applied using FreeStyle Libre 3 to evaluate glucose variability in response to various food intakes and exercise. The subject was a 45-year-old registered nurse with a BMI of 17.9. When she drank 500 cc of a carbonated beverage containing 23.5 g of sugar, her blood glucose increased acutely. She then exercised by jumping for 3 minutes, after which her glucose levels decreased shortly thereafter. Consumption of pound cake, pork bowl, and corn soup caused a rapid rise in blood glucose. She consistently follows a standard low-carbohydrate diet (LCD) and consumes only 15 g of nuts and soybeans for lunch, during which her blood glucose does not increase. Appropriate CGM application significantly contributes to overall well-being.
