Sleep More, Weigh Less
Sleeping an extra hour a night could help a person drop 14 pounds in a year, according to a University of Michigan researcher who ran the numbers for a 2,500 calorie per day intake. His scenario shows that when sleep replaces idle activities -- and the usual mindless snacking -- you can effortlessly cut calories by 6%. Results would vary for each person, but sleep may help in another way, too. There's evidence that getting less than 7 hours of sleep revs up your appetite, making you uncommonly hungry.
