'MasterChef's' Gordon Ramsay eats 'six or seven times a day'

"I eat like a horse," he tells Zap2it. "I have an active mind and an active body. Whenever I have trained or worked in a kitchen, I run home with a rucksack on my back and put 10 to 15 pounds of potatoes in it."

Ramsay's new cooking competition, "MasterChef," premieres Tuesday (July 27) night on FOX and he recently returned from Vietnam, where he was fascinated by the way people shop for food, cook and eat.
