We all behave like gluttons at some point - from the cookies your co-workers bring in – to Sunday dinner with the in-laws. But when you gorge yourself, you take in food faster than your body can absorb it. 
So here’s the science of stuffing yourself – what really happens. This comes from Dr. Barry Swanson, professor of human nutrition at Washington State University.  
  • When you sit down to dinner, your stomach is roughly the size of your closed fist. It doesn’t want extra helpings. So when you feel stuffed, you are – literally. 
  • You know that feeling when you can barely catch your breath after dinner? That happens when your stomach becomes distended. When you gorge yourself, your stomach can grow to 3 times its normal size, then it starts pushing against your lungs and diaphragm.
  • If you overeat, some of the food may not immediately reach your stomach. It chills out in your esophagus – causing acid-reflux related belching and nausea. 
  • Another by-product of gluttony: Your liver has to work overtime to digest all that extra food. 
  • Basically, your gastro-intestinal system gets stressed out from your pig out, and most of the time, it can’t take it. Your body will start to rebel and look for a way to unload the overload – if you know what I mean.
