"After a 10-hour overnight fast (not eating or drinking anything except water), participants will complete a mixed meal tolerance test (MMTT):~This involves participants drinking a Boost drink, like a milkshake, which will raise participants' blood sugar.~The amount of Boost will be based on participants body weight, up to a maximum of 360 mL or about 1 ½ cups, and should be consumed within 5 minutes.~An IV will be placed in participants arm and blood will be drawn from it. Blood will be drawn from the IV before and then 6 times over the next 2 hours after participants drink the Boost."
