Do you ever notice hunger and intentionally ignore it? Why? If it's an attempt to control your weight you are sorely mistaken. Eating when you are hungry doesn't make you gain weight. And not eating when you are hungry doesn't make you lose weight.
Equally true if you are using methods so suppress your hunger such as drinking water, diet soda, coffee or any other beverage. Or perhaps you smoke, chew gum, or try to fill up on low-calorie foods like baby carrots. These things will give your stomach an artificial sensation of fullness – a fake out because there's not real nutrition attached to it. Hunger is your body's desire for calories and nutrients.
Hunger is your friend, not your enemy. It's a message from your body telling you what it needs. The disconnection from our bodies and dismissal of body signals is where we've gone astray. People who eat when they are hungry and stop when they are satisfied effortlessly maintain a weight that is normal and healthy for their body.
