In a human’s lifetime, they spend 5 years total eating. In a lifetime, a human eats 7,000 times their weight in food!
There is a 20 minutes delay from when you start eating until you start feeling full.
Feeling “full” is a function of the brain, and not the stomach. Feeling full is the result of the brain reacting to chemicals released when food or drink is placed in the stomach. The brain takes around 20 minutes to register these chemicals. After the meal, the levels continue to rise over 10 to 30 minutes. They stay elevated for three to five hours following the meal.
