Obesity and Biology

obesity and Biology Obesity isnt classified as an eating difficulty anymore. It is more than that a persons biology plays a boastfully roll. Cells and internal secretions play a big roll on how big you be and how your body regulates zilch. intellectual nourishment equals energy and the body stores that energy in complete cells and uses the energy as needed. The metabolism breaks down that nourishment and uses the energy gene betrayed from that food for everyday activities a great deal(prenominal) as walking, talking, thinking. The faster geniuss metabolism is the more businesslike they argon at breaking down food and using the energy.The long-playing the metabolism the more energy chafes stored and gets turned into juicy cells and non used. The hormone leptin, which is produced in fat cells, sends signals to the brain telling it that its levels be dropping which elbow room the cells are reducing. When this occurs the brain processes that information as starvation a nd sends signals back to behind down the metabolism and store as much energy as possible. There are people who eat less than other alone still gain charge. Thats a biological trouble. There are areas in the brain research has found that if discredited dirty dog subscribe to to obesity.One such area is the ventromedial hypothalamus and the surrounding axons. If this area in the brain is damaged at then this can lead to overeating and more storing of fat cells. Research conducted on rats at the University of Nebraska looked at this area in the brain and how it affects food intake and body weight. With damage to that area the rat nearly tripled in size in the cores of about sixty days. Food intake does not always correspond to body weight. It is possible to as well eat and not gain weight. It just matters how active one is and how businesslike the metabolism is.There are other areas in the brain located in the prefrontal cortex that also can affect body weight. Those areas are r esponsible for food-seeking behaviors. If one is always hooked on seeking risque fat food such as burgers and high sugar drinks such as coke then that can lead to an overweight problem. The problem with sugared drinks such as coke is that it is high in levulose sugar and that particular sugar does not raise insulin or leptin as other sugars do. So you drink more of the soda, which equates to more calories without satiety. The brain is not the only factor in weight another factor can be transmitteds.Your gene makeup can be responsible for how much energy you store, and thats all been passed down to you from your ancestors. If your ancestors were only getting by in life by eating very little as about 1000 calories a day and storing a lot of energy in fat cells and using that energy efficiently then that government agency you should not eat foods that are high in fat. The reason is your genetic makeup structures your body to store more energy from food. Those whose body is structu red like this that eat a normal dieting of about 2500 calories a day will gain weight.That is due to the fact that the genes were from the ancestors thought a normal diet of about 1000 calories was good enough to get them by. In America most foods you find these days have a lot of fat in them. Good tasting unhealthy food is cheaper than healthy food. A burger is way cheaper than a salad these days. The American life direction requires people to be able to get food quickly. No one likes waiting anymore and barely anyone cooks anymore. Home kitchens are beginning to decrease as Americans waist size is beginning to grow. Fast food restaurants screen almost every business street.Americans eating lifestyle is one of the biggest factors in their weight. Obese people who lose weight end up gaining it righteousness back because the brain thinks the body is starving because there are not enough fat cells that it was normally used to. A person that loses weight cannot eat the same amount as a person who is by nature at that weight. They have to eat about 500 calories less in order to maintain their new weight. Its not only a unstable diet they have to be on, but a lifetime diet if they want to keep the weight off and they have to exercise everyday.
