Anyone who's ever been inspired to down as many franks as possible by the Nathan's Hot Dog competition has come up against a quick and harsh reality: you can't eat that many hot dogs without preparation. The stomach is a muscle like any other. It needs training and recovery, otherwise you risk injury. If you want to increase your stomach's capacity, take it slow.  According to some studies, the average human stomach holds about 1.5 liters before becoming nauseated, but can hold between 3-5 liters if trained properly. It is possible to rupture your stomach if you eat too much too quickly, but it's extremely uncommon and rare. You'll usually vomit before you risk a stomach tear or other physical problems. The healthiest way of training and expanding your stomach capacity is not with food, but with water. Competitive eaters are able to drink as much as a gallon of water at a time, in less than 20 minutes. This increases the stomach's capacity and carries relatively little health impact, compared with eating lots of food at once. Start slow, increasing the number of glasses of water you drink in a day incrementally, then increasing the speed at which you consume the water you drink. It's usually recommended to drink as many as eight glasses of water in a day to begin with, so start there and gradually build up your capacity. Water serves a purpose during eating competitions, as well as during your training. While dunking a hot dog bun in water might not seem that appetizing, it helps to break down the food before you put it into your mouth, making it much easier to swallow and start digesting. The faster you get it down, the more you'll be able to eat, and water helps this process. Don't drink too much of the water while you're eating. While it's ok to use some water to help lubricate the food, don't gulp it to quench your thirst, or you'll be taking up valuable real estate in your stomach.
