Appetite, small things but can have a big impact on you. Uncontrolled appetite can make you eat more and eventually lead to excessive weight gain. Or, it could be the other way around if you lose your appetite, then your body's nutritional needs cannot be fulfilled and in the end it can make your body thin and your immune system decreases. Maybe you consider it trivial, but your appetite has a big influence on your diet and health. What are the things that can increase appetite? Previously, we must first know how appetite occurs.
What is appetite?
Appetite or appetite is your desire to eat. This desire makes you eat to provide the nutrients your body needs. So that, maintained appetite is good for you and your health.
Appetite will usually appear when you are hungry. Hunger is an uncomfortable feeling that arises when your body needs to eat. However, your appetite may appear when you actually don't feel hungry, this can occur due to various factors. This is what you should be aware of, the appetite that often appears without hunger will usually cause you to overeat. Overeating will then cause you to become overweight.
What can reduce and increase appetite?
Appetite is a very complex thing, involving brain and hormone interactions and is influenced by habits, external cues, and emotions. Many factors can reduce and increase your appetite, can be from factors in the body or factors from the outside environment.
1. Hormones that affect appetite
Hormones function to maintain balance in your body. Your digestive system also involves hormones to support its work. Some hormones that affect appetite are:
Leptin
Leptin is a hormone that suppresses appetite You. This hormone is released by fat cells in the body. Leptin levels in the body peak when you have eaten or when you are full. So, when you have eaten a lot and are full, then your appetite is lost because of the work of this leptin hormone.
Because leptin is produced by fat cells, the amount of leptin in a person's body is proportional to the amount of fat in the body. However, in obese people, leptin resistance usually occurs, so the person is not sensitive to satiety signals.
Ghrelin
This hormone is the opposite of leptin. If leptin suppresses appetite, then ghrelin trigger appetite. This hormone is released by the stomach when the stomach is empty and requires food. The hormone ghrelin increases in number before the meal and then decreases in number when you have eaten. "This happens naturally every four hours," Nolan Cohn said, quoted from Today's Dietitian.
In obese people, the level of the hormone ghrelin is lower. However, obese people are more sensitive to appetite stimuli.
Other hormones that also affect your appetite include somatostatin, amiline, cholecystokinin, glucagon, insulin, and others.
2. The nervous system that affects appetite
Besides hormones, the nervous system through neurotransmitters (compounds similar to hormones) can also affect your appetite. Some neurotransmitters that affect appetite are:
Neuropeptide Y
Ghrelin communicates with the brain and triggers the release of neurotransmitters called neuropeptides Y. This hormone is released by the hypothalamus which also functions to stimulates hunger. These neurotransmitters are usually released when body fat is low or when the body has started to lack food. In the intestine, neuropeptide Y can slow gastric emptying and food transit time.
Dopamine
Dopamine is a brain neurotransmitter associated with satiety hormones (suppresses appetite) Dopamine can activate pleasure centers in the brain that can affect mood and food intake. Dopamine levels can increase because of the intake of foods high in fat and sugar, both types of food can increase pleasure. However, both types of food can also increase appetite, so you overeat and cause you to gain weight.
Other neurotransmitters that also affect your appetite include serotonin, norepinephrine, acetylcholine, and others.
3. Social environment
The social environment also influences your appetite. For example, eating with friends or family can increase appetite. Your appetite can also increase when you eat at a time and in a place that suits you.
4. Food appearance
For example, the size of food, food packaging, taste and texture of food, and the aroma of food. Usually you have more appetite to eat if the appearance of the food matches your preferences.
5. Emotions and psychological
Stress, anxiety, and discomfort can make your appetite disappear or vice versa depending on the individual. Indirectly, your emotions also affect your appetite.
6. Habits or routines
Appetite can also arise due to eating habits or eating routines that you often do. This can also be related to the culture in the environment around you. For example, there is a birthday cake on birthday celebrations, eating habits with friends on Friday nights, or relaxing with family while snacking in front of the TV every day off, and so on.
