The nerves inside the body detects the pressure and if the stomach is heavy then it means full.
Actually brain tells to stop eating if you further try to eat and enlarge the stomach the reverse pressure is created and you may vomit the food.
Nerve cells in your stomach send a signal to your brain when your stomach is "full".
When you feel really bloated and feel like u cant eat anything more is an idication u have eaten 2 much so just b4 you reach that stage ul realize ur belly is full and so should stop eating.
There is a certain point when your body needs the energy, or food, to continue to run. Your brain will then receive a message saying that you need to eat, also known as feeling hungry.
You can eat an apple before a meal, or have peanut butter during a meal. These foods give the illusion of being full, and will not crash a diet unless you have eaten too much.
Your brain.
Yes, it does.
It makes chemicals. For example, chemicals from and to the brain and stomach help you to know when you are hungry/full.
There appear to be three. The brain interacts with gut hormones such as PYY (peptide tyrosine tyrosine) and ghrelin and fat hormones such as leptin to control appetite and body weight. The brain says you are full.
That you need to eat to restore energy levels and give your body the required nutrients. As simple as that.
Being hungry means feeling a strong desire or need for food due to an empty stomach or low blood sugar levels. It is the body's way of signaling that it needs nourishment to function properly.
I am hungry
Nerves and brain cells in the brain send electric signals to each other to tell the body what to do.
I think the answer you're looking for is nerves. Nerves are the types of cells that transmit signals from your body to your brain, and brain to your body. Nerve cells release charged molecules in a controlled way to create electrical signals that can propagate information across the body.
Your brain is a very hungry organ. It weighs only a 50th of your body weight, yet consumes one fifth of your energy.
what the brain tells you is how to control your functions in your body, how to do school work, how to play, etc.
Neurons transmit messages to and from the brain.
