Appetite Control, Hunger
Eating Patterns: What Determines Appetite, Hunger, Calorie-Intake and Body Weight
Appetite, Hunger and Weight
To be able to control your food intake and maintain a healthy weight, you need to understand why you feel the need to eat.
Appetite & Food Intake
Experts believe that basically, three factors regulate food intake including:
Experts believe that appetite is influenced by the brain stem, which is independent of the hypothalamus. The hunger center stimulates an individual to eat while the satiety center extinguishes the need for food. The appetite also stimulates a person to eat.
Appetite is often referred to in the same sense as hunger. It includes and is influenced by time of day, smell, and sight of food.
Appetite is Learned
However, appetite relates to the desire for specific types of food and eating experiences, instead of food in general.
Appetite helps select the quality and balance of food as learned by an individual in his or her environment.
Appetite and Hunger Center
The hunger center is responsible for the long term, metabolic, regulation of food intake over weeks and months. The hunger center maintains normal quantities of nutrient stores and controls physiological hunger. The hunger center is influenced by the following factors:
Hunger vs. Appetite
Appetite & Eating Control - Upper Gastrointestinal Tract Nerves
When you overeat and overstretch the abdominal cavity, nerves in the upper gastrointestinal tract signal to stop eating. This is particularly important in bringing a halt to a heavy meal and explains why drinking water before a meal or why having soup with a meal can reduce total calories consumed. When these "eating factors" controlled in the brain stem have been satisfied, the hunger center in the hypothalamus becomes temporarily inhibited.
Since complete inhibition of the hypothalamus does not occur until both hunger and appetite are satisfied, you may desire food soon after you have eaten if appetite has been satisfied but not hunger. This also explains why people eat when they do not have hunger.
Use Appetite to Control Hunger for Healthy Weight
The fundamental principle underlying adequate eating is to use your appetite to control your hunger.
If you wait to eat until you are physiologically hungry, you may eat four or five times the amount you need to fill the nutritional stores. Many people skip meals and then "pig out."
It is relatively easy to fight off your appetite but nearly impossible to fight off your hunger. To prevent this situation from occurring, eat nutrient balanced meals every day, avoid allowing yourself to become physiologically hungry by using your appetite to control your hunger.
Hunger, Appetite & Satiety
Satiety, the opposite of hunger and appetite, indicates a feeling of fulfillment in the quest for food. Satiety occurs when your nutritional storage deposits, such as the adipose or fat tissue, and glycogen stores are filled. The appetite is satisfied when a person's learned nutritional needs are satisfied.
Balance Hunger, Appetite & Satiety
