Last year, Travion Shinault weighed 370 pounds. In January, 19-year-old “Tray” had one of the first teen bariatric surgeries at Children’s Hospital Colorado, where doctors shrunk his stomach to the size of a banana. Now, the 6-foot-4 teenager weighs 325 pounds. “My biggest thing was losing weight because I wanted to feel like I belonged in this world,” said Tray, whose goal is 270 pounds.
