Why do some people eat too much? Is it because they're hungry? Or is there a scientific{#blank#}1{#/blank#}(explain)?

    There are a number of theories to account{#blank#}2{#/blank#}overeating. One factor depends on the time of day. “It's all part of a routine,” says Randy Seeley,{#blank#}3{#/blank#}professor of psychiatry in Cincinnati. “You're hungry at noon because that's the time you{#blank#}4{#/blank#}(eat)lunch for the past 100 days.” Another reason we may eat more than necessary is that the body needs to satisfy a salt and sugar balance. Drinking alcohol also increases appetite, because the body wants something {#blank#}5{#/blank#}(absorb) the alcohol.

    {#blank#}6{#/blank#}(basic), overeating can also be a question of more biological factors. For instance, your body temperature can tell your brain that you feel hungry. “Your body temperature{#blank#}7{#/blank#}(drop) when it's time to eat, and eating warms you up,” says Gina Harlow, a paediatrics professor at Harvard University. Also, the smell of certain foods can make us imagine subconsciously the pleasure of eating{#blank#}8{#/blank#}. Harlow adds, “If you know you love French fires,{#blank#}9{#/blank#} (smell)them will make you want to eat them because you know how good they are,{#blank#}10{#/blank#}can lead to eating too many.”

    So, the next time you realize you've eaten too much, don't worry about it. You can always blame it on science.
