Fitness means good health or physical condition, especially as the result of exercise and proper nutrition. One individual may need fewer calories than another, depending on metabolism. Some people might prefer easier exercise to more strenuous exercise. Understanding the needs of your own body is the key. Even though no one can be sure of avoiding chronic diseases, poor diet can definitely ruin good health. With the change of your eating habits, you can reduce the damage or lower the risk of disease. Poor eating habits, such as eating too much junk food, might result in having extra kilograms. Although gaining a few extra kilograms doesn’t always mean you are overweight, it can be hazardous to your health. Unlike the muscle-bound athletes, for most people, the kilograms they are packing are fat, instead of muscle. Extra kilograms can decrease your life expectancy while increasing the risk of health problems, such as high blood pressure, heart enlargement, high blood cholesterol levels, heart attacks, adult-onset diabetes, colon and prostate cancers in men; and breast and uterine cancers in women, and osteoarthritis. For a typical adult who would like to know whether they have excessive body weight, the body mass index (BMI) is the best indicator. The BMI is a common measure expressing the ratio of weight to height. It is a statistical measurement comparing an individual’s weight and height. Because measuring and calculating one’s BMI is an easy task for most people, it is currently the most widely used diagnostic tool to identify weight problems within a population, including underweight, overweight and obesity. With this simple formula — an individual’s body weight divided by the square of his height — he can calculate if he should drop a few kilograms or not. For example, a person weighing 55 kilograms, with a height of 1.65 meters, would have a healthy BMI of 20.2 [55/(1.65)2 =20.2]. For adults, a BMI ranging from 18.5 to 24.9 is considered normal. If your BMI is between 25 and 29.9, you are overweight, while anyone with a BMI of 30 or more is considered obese. Good health is not something you are able to buy at any drugstore. You cannot depend on getting it back just with a quick visit to the doctor when you are sick, either. Instead, you should do exercise on a regular basis and keep a balanced diet if you want to have good physical condition. You are the one who is responsible to make your body last without major problems. Mistreating your system by keeping bad eating habits, neglecting symptoms of illnesses, and ignoring common health rules can indeed counteract the best medical care.
