    View full lesson:
    Hunger claws at your belly. It tugs at your intestines, which begin to writhe, aching to be fed. Being hungry generates a powerful and often unpleasant physical sensation that’s almost impossible to ignore. After you’ve reacted by gorging on your morning pancakes, you start to experience an opposing force: fullness. But how does your body actually know when you’re full? Hilary Coller explains.

  • ViolettaVie

    I don't think this is accurate. Your stomach does not signal that you are hungry. That uncomfortable feeling is the detoxification process. Hunger is signaled in the throat.
    If you have ever fasted, once your body gets finishes detoxifying, you will feel fine for a while, and not even hungry. Then you will start to feel thirsty and want to eat.

    When you are full, sure...This is supposed to be more or less cultural video. A glass with water in it
    can be full. A person is satiate or satisfied. Of course many people use it but that doesnt make it right.

    I usually ignore whenever my stomach starts to growl (which is basically everyday for me). I usually have only one meal per day anyway. (BTW, I'm 20 and 103 pounds.)

      Danly thats not a healthy weight...try not to ignore you're hungry and slowly maximize you're meals.
