    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.

    I think we have two stomachs, one is for everything and the second one is just for french fries and ice cream, but your first stomach, the one where every food can go, is priority, so if you eat ice cream and french fries first you're going to be full but you won't eat the rest of the food, so first you need to eat all the normal food, to full your first stomach and then eat ice cream and french fries, (other foods like sushi can also be allowed in the second stomach)

  • 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.
