You can't stop eating even when you're full because your brain is still trying to figure out if you're getting enough of the nutrients it needs. It does this by taking into account all the different sources of information about food, including sight, smell, taste, texture, and temperature. u003cbr/u003eu003cbr/u003eOnce it has all that information, it runs it through a u0022u003cstrongu003esatiety algorithmu003c/strongu003eu0022 to determine whether or not you should keep eating. So, if you're not getting enough of the nutrients you need overall, your brain might keep sending you signals that it's time to eat, even after you're already full. This is one of the reasons it's so important to eat a balanced diet: if you're not getting enough of the nutrients your body needs, you might end up overeating, even when you're not hungry.
