I was just wondering why I get SO thirsty after a binge (lasting from a couple of hours afterwards and continuing into the next day). Of course, this is apart from the bloating and gassy feeling from shoving more food into my body than it needs.
Most binges are carb-heavy, right? And every gram of carbs that you eat holds on to 3 - 4 grams of water. So lots of carbs means lots of thirst since your body needs more water - the excess carbs are sucking it up.
This water retention after a carb binge is why someone can gain huge amounts of weight overnight, even though the calories consumed weren't that many.
