By the end of the holiday season, many of us had eaten too many delicious chocolates or crispy
potatoes. So what happens to your body if you overeat? If you’ve just polished a plate full of groceries,
sometimes you feel like you’re going to explode.
Although it is possible that your stomach will tear after eating too much, your gag reflex will likely start
long before you reach this point. The average human stomach can take in between a liter and a half of
food before it is thrown away, but it can stretch to take up four times more space before it breaks.
When you eat a meal high in fat, sugar and carbohydrates, your parasympathetic nervous system makes
your body slow down and focus on digesting food, making you feel sluggish. As food is digested, the cells
in your pancreas produce the hormone insulin, which in turn causes an increase in melatonin and
serotonin, hormones that make you both drowsy and happy. You may also have trouble keeping your
eyes open when the glucose levels in the foods you eat increase. This can disrupt the neurons in your
brain that normally produce the orexin proteins that are responsible for keeping you awake and alert.
