Eating a meal with no carbohydrates stops blood sugar from dropping too low after eating and keeps it within a normal, healthy range.
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.
When trained male cyclists follow the same diet and exercise routine, their blood glucose levels can vary by as much as 30 mg/dL between individuals, suggesting that a one-size-fits-all nutrition approach may not be effective for everyone.
In endurance athletes, the intensity of exercise—measured relative to their individual performance threshold—is the main factor that causes glucose levels in the tissue fluid to rise during training, regardless of how many carbohydrates they eat.
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.
