Dangers of Obesity


Weight control is a process of eliminating or avoiding the accumulation of fat in the body. This depends on the relationship between the amount of food consumed by the amount of energy used. Little did you eat and more energy is released, then you will lose fat. Weight control is very important for health because of obesity (too fat) can cause heart problems. Obesity is a serious disease that can lead to emotional and social problems. People who are overweight (obese) may not obese, but overweight words often used for people suffering from obesity. Being overweight means having a body weight above the average for a certain height.
Some people have a body weight below average because they have smaller bones and muscles. While others have a weight below average due to less fat accumulation. In this case the lack of weight does not mean less healthy. But many also have a weight below average caused by diseases such as cancer, diabetes, or tuberculosis. Some children have a weight below the average could be early signs of growth. People who have a body weight below the average should consult with your doctor, if not find a disease, then do not have to worry about.
People who are not too fat do not need to lose weight for health reasons. To keep the body healthy enough with a simple exercise such as walking or exercising.
Dangers of obesity
People who are too fat compared with thinner people more susceptible to certain diseases. Treatment of these diseases among obese people are often less successful. Certain illnesses such as appendicitis, cirrhosis, diabetes, and heart and blood vessel disease, especially coronary heart disease. Patients with one of these diseases, being overweight is more easily treated if they lose weight.
People who are very obese will easily fall in and easily have an accident other than thinner people, because they are slow and awkward. Often more difficult to heal from the wounds meraka for doing surgery on them is very complicated. Obesity has cut their freedom of movement, especially in the elderly, which can lead to lower overall health due to lack of exercise. The decrease freedom of movement in patients with rheumatoid arthritis obesity, resulting in difficulty in healing.
In some parts of the hemisphere, obese people may be denied in many ways. Fat people are often not treated well by others, including classmates at school. In general they are less successful than others in the association and they are more difficult to get a job.
Causes of obesity
OvereatingYou can raise or lower the weight as a result of eating too much or too little calories than you need. Calorie is a unit for measuring heat energy produced by the body of a certain amount of food. If you eat more calories than you need, the excess will be converted into fat in the body. If you eat less than that needed by the body will convert fat into energy. In a few days or several weeks if you eat 3,500 calories more than necessary you will go up 0.5 kg. You will lose the same weight if you eat less than 3500 calories than necessary.
Additional calories are needed for a growing child and the woman pregnant. But they will become overweight if you eat too many calories.
Amount of food that you eat can play an important role in regulating body weight compared with other types of food. People who are overweight than normal weight or less, so they can eat the same foods. Their body weight differences caused by the amount and type of food that relate to the amount of energy they use.
Certain centers in the brain controls appetite, hunger, and satiety, the feeling that causes you to stop eating when your appetite and hunger has been satisfied. This brain center normally make people eat a certain amount sufficient to provide power for them. Centre resulted people want to eat food. Satiety center brake food center checkers make people stop eating.
Center for food and satiety center is a very complicated mechanism. They may be disturbed by certain causes such as emotional stress and physical character. For example, such feelings are very disappointed pressure can cause some people to stop doing all physical activities. At the same time the person is eating more than usual, and gained weight. While the others too much motion and less food and lost weight.
Some scientists believe that giving food to the baby too much can cause a lot of developing fat cells. They stated that these cells may lead to the formation of fat quickly than the ordinary person, so that obesity can result in the future.
Physical inactivity is a major cause of obesity among all age groups, especially among children and adolescents. Though most people with obesity among children and adolescents eat in an amount not more than their normal weight. But they are not very active so despite having the appetite that is, they eat more than they need to move, and terkumpulah excessive fat.
Exercise to burn calories. The more vigorous exercise, the more calories are used. A person weighing 68 kg runs at a speed of 5.6 km per hour will burn 502 calories during 97 minutes (same calorie drink a glass of milk powder). The person will burn the same number of calories as riding a bike for 61 minutes, or run for 26 minutes.
The number of calories used is proportional to weight. If you weight 50 kg then it will use half the amount of calories needed person who weighs 100 kg for the same type of exercise in the same period.
Appetite active people can go up if they become very active. If they turn off, their appetite will not come down immediately. Appetite will not come down to the lowest position even if the activity has dropped dramatically.
OffspringMany scientists investigated the relationship between heredity and obesity in animals, especially rats. This relationship is based on the gene, the main unit in the cell that determines the characteristics of offspring. Scientists have found that mice and other animals have the gene that causes the satiety center is not operating. Another gene in mice resulted in some of their body produces certain hormones in excess. As a result of these hormones make the mouse easy to generate body fat or very difficult to burn body fat. Another gene that resulted in some mice become obese quickly than the other rats when in a state of physical inactivity or when given food containing fat.
The scientists suspect that genes might cause obesity in humans because the weight of a child's weight is often associated with their parents. In the study of high school children, only 8 percent of students with parents who lean to obese. If one or both parents were obese, about three quarters of them become obese. But the weight of adopted children does not depend on their adoptive parents. In 1994 scientists announced the discovery of the first gene is believed to have anything to do with obesity for humans. Since then the researchers found that other genes that seem to play a role for human obesity.
Disease and other causesObesity may be caused by several types of diseases. Several endocrine diseases caused by these glands release too many hormones into the bloodstream. The excess hormones interfere with the food center and satisfaction in the brain. Thus, obesity can be caused by damage to these centers caused by infection, injury or tumor.
HOW TO CONTROL Obesity
You should consult with a physician before starting a weight loss program extensively. Advice of a dietician is also very useful. An obese patient may require the help of a psychiatrist, especially if he's still young and plagued by feelings of guilt, despair, or feel worthless. Psychiatric care can help eliminate these feelings so that obesity can be treated medically.
DietThe first step to lose weight is to develop a healthy diet that can stop weight gain. Some weight-loss diet should provide fewer calories. If a person requires 3000 calories per day to maintain weight on a habit of his life, he should eat 2000 calories per day to remove 0.9 kg of body weight per week. In general, very dangerous to lose weight quickly.
The food in the diet should be healthy balanced. Food should provide all the nutrients needed for good health in sufficient quantities. There is no evidence that extreme diets like low carb, low protein, or a diet based on one type of food, has many advantages over a healthy balanced diet. Diet to lose weight should also have a good taste and easy to buy and serve.
Someone who lose weight have to learn a list of the number of calories contained in various types of food. Many people believe that certain foods such as roasted potatoes and toast have more calories than usual. They also estimate a lower amount of calories in certain foods such as steak.
Distribution of calories among the main foods and snacks depending on each person. Some people do not feel very hungry when they divide their caloric needs into 4 or 5 snack or light meal each day. But others can follow the way of eating better if they eat 3 main meals per day and no snacks.
ExercisePeople who run weight-loss diet should do more exercise. But an able-bodied people with obesity, although not all of a sudden start with heavy exercise. Very dangerous for the heart. An exercise program should be developed gradually. One good way to start is by foot every day, with increasing exercise duration. Additional training is needed for people who want thinner and thinner. Someone should do 5 to 6 hours of exercise per week. Men aged over 40, women over 50, and a person with risk factors or symptoms of heart disease or lung disease should consult a physician before starting a serious exercise program.
OperationPeople incredible fat, threatening her life and those who failed the diet have to do surgery to shrink the size of the stomach. In a certain operation called gastroplasti or gastric stapling procedure, doctors use a large clamp equipment to cover most of the patient's stomach. After surgery the patient just by eating a small amount of food it has become full.
