The patient comes fasting (12 h) in the morning, bringing the breakfast to consume. Before starting the meal, two blood samples are taken with 10 min in between. After the start of the meal, a new blood sample is collected at 10, 20, 30, 45, 60, 90, 120, and 180 min afterwards. Each blood sample consists of 6 ml plasma. At the same time intervals, the satiety score is completed. With a few days in between, the same procedure is performed where their previous ordinary, daily breakfast is replaced by the new diet, so that 2 test meals are performed during run-in; one with ordinary breakfast and one with new diet breakfast.
