    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 felt that it was not just quantity, but also quality of food which contributed to fullness... but I didn't think of hormones. Thanks!

    Your animation makes my body look so cute! I feel so safe and protected with an army of smiley face organs and hormones inside me! Unlike other videos that neglect to show the smiles and double down on the textures. I always feel iccy afterwards.

    This isn't true, the feeling of fullness comes from hearing. Wear earplugs while you eat in a quiet atmosphere (no tv, no family talking) you will get full faster and you will lose weight.

    Strange Question: Could your intake of food increase, I remember not that long ago I could eat a small meal in the morning and not be hungry until nighttime, but now even if I eat a big meal I'll get hungry in 2 hours flat.
    Could increase intake of food cause you to get more hungry faster than others?
