Skinny people win eating contests

PopSci uses a biology lesson to explain why skinny guys always win eating contests.

Kobayashi's regimen includes shrinking his gut by jogging for hours, then distending it by chugging gallons of water. He regularly feasts on giant meals of low-fat, high-fiber foods like cabbage, which stay in the stomach longer before breaking down. (By the way, the world record for cabbage consumption is 6 pounds, 9 ounces, in 9 minutes, held by American Thomas Hardy.) And he keeps trim: A skinny man's stomach has little fat to push against it and fight the food for space.
