What happens when we eat late at night?
Eating at night after 8pm is said to be poison to the body. Eating at night has long been associated with weighht gain. Here, we should understand that conventional wisdom today is that a calorie is a calorie, regardless of when you eat it, and that what causes weight gain is simply eating more calories than you burn. Nutrition experts call this the calorie in/calorie out theory of weight control.
Also, it does not matter what time of day you eat. It is what and how much you eat and how much physical activity you do during the whole day that determines whether you gain, lose, or maintain your weight.”
A study in the journal OBESITY added to the confusion by suggesting that there may be more to nighttime eating than just overeating calories. Northwestern University researchers found that eating at night led to twice as much weight gain — even when total calories consumed were the same. But this research was done on mice, not humans, and the reason for the weight gain is unknown. And a single mouse study should not cause us to toss out the wealth of evidence supporting the calorie in/calorie out theory
Now we need to note that People eat at night for different reasons that often have little to do with hunger, from satisfying cravings to coping with boredom or stress. And after-dinner snacks tend not to be controlled. They often consist of large portions of high-calorie foods (like chips, cookies, candy), eaten while sitting in front of the television or computer.
