Does your stomach really shrink and stretch depending on how much you eat?
Your stomach is an elastic organ, so when you take in a large volume of food, liquid, or air (think carbonation), it does expand to accommodate everything that’s put into it. But it starts to shrink back to its normal size once the meal has passed out of the stomach. So overeating on occasion won’t permanently expand your stomach and in turn won’t make you hungrier.
