Why do some people eat too much? Is it because they're hungry? Or is there a scientific(explain)?
There are a number of theories to accountovereating. One factor depends on the time of day. “It's all part of a routine,” says Randy Seeley,professor of psychiatry in Cincinnati. “You're hungry at noon because that's the time you(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 (absorb) the alcohol.
(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(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. Harlow adds, “If you know you love French fires, (smell)them will make you want to eat them because you know how good they are,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.
