Have you ever had someone tell you "If you eat before bed，you are more likely to get fat!"？（1）EEThis belief originated when researchers found the relation between individuals snacking late at night and having a BMI that categorizes them as obese（肥胖的）。
Is eating late at night，especially after 8 pm，really going to make you gain weight？One theory is that your metabolism（新陳代謝） slows down when you are asleep.（2）AAThus the calories you eat right before bed would not be burned off as much as they would be while you're awake.Although the science seems pretty sound，recent studies have shown that metabolism changes very little，if at all，while you are asleep.（3）BBThe heart is still beating，lungs are still working，and the brain is still very active.All of these actions take energy，meaning while we are asleep，we are still burning calories.
（4）GGAs we know，one physiological effect of insulin（胰島素）is storing fat.Food being consumed late at night will more likely be stored away due to the higher levels of insulin present in the blood system.However，insulin levels at night are shown to be no different than insulin levels during mid-day.If it is true that eating with high insulin levels causes you to gain weight，anyone eating anytime after the morning will become fat.
So how come individuals have higher BMI s when they snack at night？It is simply a result of eating too many calories.Snacks that individuals tend to eat during the night are usually high in sugar and calories，such as ice cream，candy，potato chips and soft drinks.Put simply，if you eat more calories than you burn，regardless of the time of the day，you will gain weight.（5）DD
A.With a slow metabolism，few calories are being burned.
B.While asleep，your body still functions in many ways.
C.All living matter undergoes a process of metabolism.
D.The time these snacks are consumed does not matter.
E.Without ever questioning it，people quickly assume this to be true.
F.Besides，insulin levels are dramatically lower in the morning than at night.
G.Another theory is that late-night snacking leads to rising insulin levels.
