In trained male cyclists, exercising the day before leads to a small decrease in blood glucose levels during the night, regardless of how many carbohydrates were consumed.

In trained male cyclists, switching to a diet with very little carbohydrate for seven days lowers average glucose levels in the body and reduces fluctuations in glucose compared to a diet high in carbohydrates.

Doing four minutes of exercise each day is associated with lower blood glucose levels in people diagnosed with Type 2 diabetes.

Among trained male cyclists, consuming a diet high in carbohydrates results in a higher amount of time during exercise with blood glucose levels between 121 and 180 mg/dL compared to a low-carbohydrate diet, reflecting larger increases in blood glucose after eating and training.
