Obesity and Biology

obesity and Biology Obesity isnt classified as an eating line anymore. It is more than that a persons biology plays a titanic roll. Cells and internal secretions play a big roll on how big you ar and how your body regulates energy. viands equals energy and the body stores that energy in risque cells and uses the energy as needed. The metabolism breaks down that viands and uses the energy gene hindquartersed from that fare for everyday activities such(prenominal) as walking, talking, thinking. The faster angiotensin-converting enzymes metabolism is the more competent they atomic number 18 at breaking down food and using the energy.The long-playing the metabolism the more energy hails stored and gets turned into expound 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 government agency the cells are reducing. When this occurs the brain processes that information as starvati on and sends signals back to deadening down the metabolism and store as often energy as possible. There are people who eat less than other only when still gain angle. Thats a biological task. There are areas in the brain research has found that if alter send away get going 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 also eat and not gain weight. It just matters how active one is and how effectual the metabolism is.There are other areas in the brain located in the prefrontal cortex that also can affect body weight. Those areas are respo nsible for food-seeking behaviors. If one is always hooked on seeking elevated 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 fructose 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 genetics.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 bureau 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 organise like this that eat a normal diet 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 vogue requires people to be able to get food quickly. No one likes waiting anymore and barely anyone cooks anymore. Home kitchens are beginning to repress as Americans waist size is beginning to grow. Fast food restaurants covert 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 ripe(p) 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 fugacious diet they have to be on, but a lifetime diet if they want to keep the weight off and they have to exercise everyday.
