Very little, it turns out. There are about 9 food calories in a gram of fat, so in theory you could gain one pound of fat (454 g) by eating some 4,000 calories more than you burn. The actual number may be closer to 3,500, so if you eat 500 extra calories per day for a week, you might gain a pound of fat.
