of the most powerful means of appetite suppression that the human body has. Peptide YY and Insulin After the release of CCK, a number of other hormones begin to activate in order to decrease your desire for food. As food begins to leave your stomach and cycle through your digestive tract, you start to produce another hormone known as Peptide YY, which gives more signals to the brain that you have had enough to eat. In addition to this, the pancreas starts to secrete Insulin in order to control and regulate blood sugar, which also has a suppressive effect upon digestion. Digestion Signals Satiation When your body starts the process of serious digestion, it stops being interested in eating. This is why you always hear the suggestion that you should eat slowly and chew your food for long periods of time. The longer it takes you to eat, the less food that you will eat before your brain starts to shut down appetite. Importance of Leptin On top of all this, fat cells throughout your body produce a hormone known as leptin, which serves a similar purpose to Ghrelin, telling the hypothalamus that you don't need to eat anymore. Upon stimulation by Leptin, the hypothalamus releases Alpha-MSH, another power hormone that eliminates the desire for food. Hunger is Complicated All of these different hormones play their own special role in cultivating the delicate balance between satiation and hunger. You may wonder why so many hormones are involved in your sense of hunger. This is because your body gets nearly everything it needs through digestion, and all of these hormones promote different aspects of hunger and fullness in order to ensure that you get a healthy amount of all the nutrients that you need without overdoing it. Obesity, a Modern Dilemma The problem is that our bodies are streamlined for a different environment than what exists in the first world, or even the modern world in general. There has never been a time in the history of the world where so much food has been available to so many people. Even the hunger that persists in the third world is not the result of a global lack of food, but because of the combination of waste and poor international distribution. In our evolutionary past, we spent our days doing everything that it took to survive, hunting and gathering for food and eating what we could, when we could. Because of this, our bodies developed an amazing ability to store fat in order to help us survive through periods where food wasn't readily available. Up until very recently, this ability was vitally important to the health and propagation of the human race. Today, however, sugars and fats exist in tremendous abundance, and because of this, our bodies have a tendency to absorb too much, far beyond that which we need in modern America. Upon accumulation of body fat, our bodies even resist fat metabolism. If you don't engage in healthy exercise in combination with diet, then your body will actually burn energy from your muscles before it will start burning fat effectively. This is why it is important not just to diet, but to engage in cardiovascular and aerobic exercise as well. Take Control of your Hunger Fatty Liver Disease and Type-Two Diabetes are serious diseases.
