Standard test meal (SM)
Participants were given a standard breakfast meal with a fat and protein content similar to their daily intake. Insulin was administered according to their individual carbohydrate-to-insulin ratio. On the test day, venous blood samples were collected from the catheter inserted for GLP-1, glucagon, and free fatty acid analysis immediately before the meal (t=0 minute) and at 30, 60, 90, 120, 240, and 360 minutes after the meal.
High fat high protein meal-carbohydrate counting (HFHP)
On the high-fat, high-protein meal-carbohydrate counting test day (HFHP), participants were given a high-fat and high-protein breakfast. Insulin was administered according to the individual carbohydrate-to-insulin ratio. On the test day, venous blood samples were collected from the catheter inserted for GLP-1, glucagon, and free fatty acid analysis immediately before the meal (t=0 minute) and at 30, 60, 90, 120, 240, and 360 minutes after the meal.
High fat high protein meal-fat counting (HFHP-a)
On the high-fat, high-protein meal-fat-counting test day (HFHP-a), participants were given a high-fat and protein breakfast. In addition to their individual carbohydrate/insulin ratio, insulin was administered based on fat counting (1 unit for every 15 g of fat after the first 15 g of fat in the meal). In this method, the insulin dose calculated based on their individual carbohydrate/insulin ratio was delivered via insulin pump as a standard bolus, while the insulin dose calculated based on their fat count was delivered as a 4 hour extended bolus.
High fat high protein meal-fat and protein counting (HFHP-b)
On the high-fat, high-protein meal-fat and protein counting test day (HFHP-b), participants were given a high-fat and protein breakfast. In addition to the individual carbohydrate/insulin ratio, insulin was administered according to the adapted Pankowska Algorithm (1 FPU for every 100 kcal after the first 200 kcal of the meal). In this method, the insulin dose calculated based on the individual carbohydrate/insulin ratio was delivered as a standard bolus by an insulin pump, while the insulin dose calculated based on the fat and protein count was delivered as a spread over 4 hours.
