The average weights of American men (191) and women (164) have increased 25 pounds since 1960. And according to one study, in 2003, Americans' 223 million cars and light trucks burned an extra 39 million gallons of fuel for every additional pound of passenger weight. So Americans are using almost a billion gallons of gasoline more each year than they would if they were as (comparatively) svelte as they were in 1960.
