"It’s because the chemicals from the stomach to the brain take too long to say that it’s full."

I read a long long time ago that there's a 20 minute delay. That's why it's better to eat slow, one may eat less but the time the 20 minutes are up.

Drink a glass of water and eat a slice of bread 30 minutes before mealtime. By mealtime your brain will have gotten the message that you’ve eaten and you will tend to eat less during the meal.

Simple diet plan.
