Diet adjustment
Before the activity:
If you just had a meal or your blood sugar is> 10 mmol/L without ketones, it is not necessary to eat food with carbohydrates in addition to your usual diet plan.
If your blood sugar is <7 mmol/L, you should have a small snack of 10 g to 20 g of carbohydrates (see the table on the next page for examples).
During the activity:
If the activity is of low intensity: It is not necessary to consume food during exercise to prevent hypoglycemia.
If the activity is of medium intensity: Provide 10–20 g of carbohydrates per hour of exercise.
If the activity is of high intensity: Allow 10–20 g of carbohydrates per 30 minutes of exercise.
After the activity: If you practise your activity in the morning or afternoon, you should have your usual snack after your sports period.
If you practise your physical activity in the evening, make sure you have a snack with a slightly higher carbohydrate content and a source of protein to prevent hypoglycemia at night.
