What blood glucose level indicates that carbohydrates should be consumed around exercise?

The recommended blood glucose level indicating that carbohydrates should be consumed around exercise is below 120 mg/dL. This threshold is critical because maintaining adequate energy levels during physical activity is essential for optimal performance and endurance. When blood glucose levels fall below this point, it suggests that glycogen stores may be insufficient to meet the demands of exercise, particularly in endurance sports or prolonged physical activity.

By consuming carbohydrates when blood glucose is at or below 120 mg/dL, individuals can replenish energy stores and sustain performance throughout their workout. Carbohydrates are the most effective macronutrient for replenishing glycogen and providing a quick source of energy to support bodily functions and maintain blood glucose levels during exercise. Regular monitoring of blood glucose can help athletes and those involved in physical activities to strategically time their carbohydrate intake for enhanced performance and reduced risk of fatigue or hypoglycemia.
