How long does it take the stomach to signal the brain that hunger is satisfied?
20 minutes
“Hunger hormones” (ghrelin) in your blood and an empty stomach signal the brain when you’re hungry. Nerves in the stomach send signals to the brain that you’re full, but these signals can take up to 20 minutes to communicate — and by that time, you may have already eaten too much.
How does your brain know when your stomach is full?
Stretch receptors in the stomach are activated as it fills with food or water; these signal the brain directly through the vagus nerve that connects gut and brainstem. Hormonal signals are released as partially digested food enters the small intestine.
How long does it takes for your stomach to be empty?
The F.D.A. defines an empty stomach as “one hour before eating, or two hours after eating.” The F.D.A.’s two-hour rule is just a rule of thumb; the stomach will probably not be completely empty. The specific definition of an empty stomach varies from drug to drug.
Should I eat if I’m hungry late at night?

Is it OK to feel hungry?
Your body relies on food for energy, so it’s normal to feel hungry if you don’t eat for a few hours. But if your stomach has a constant rumble, even after a meal, something could be going on with your health. The medical term for extreme hunger is polyphagia. If you feel hungry all the time, see your doctor.
Is it better to eat slower?
Eating too quickly can lead to weight gain and decreased enjoyment of food. However, slowing down can increase fullness and promote weight loss. It also provides other health benefits. If you minimize your screen time, chew more, and focus on high-fiber foods, you’ll be well on your way to slower eating.
Is it rude to eat fast?
Eating at a moderate pace is important, as eating too slowly may imply a dislike of the food and eating too quickly is considered rude. Generally, it is acceptable to burp, slurp while at the table. Staring at another diner’s plate is also considered rude.
