Why is obesity dangerous to your health?
Obesity is an acute condition, in which a person accumulates so much fat in the body that will cause a negative effect directly on health. So you can imagine, how is obesity dangerous to your life. A person considered to be obese, if he or she is having body weight at least 20 % higher than a normal person. It is determined by Body Mass Index (BMI). If BMI is between 25 and 29.9, then you are having condition of overweight. BMI index over 30, considered to be obese.
Obesity potentially increases the higher risk of various type cardiovascular conditions, such as heart disease and stroke. But it commonly harm your heart and blood vessel system. It also causes various disorders like gallstones, osteoarthritis and respiratory problems. So a doctor recommends every adult to measure BMI index at least once in every year.

How BMI measured?
BMI is a statistical measurement that derived from your height and weight. It works effectively to estimate in case of a healthy body weight person. However, it can’t measure the percentage of body fat. Sometimes it measures misleading readings, like in the case of a muscleman, BMI may be high. But may have much less fat compare to an unfit person, whose BMI index is generally lower. So BMI measurement will be a useful indicator in the case of an average person.
The formulas to calculate BMI index based on two unit systems:
BMI = weight (kg)/height2 (m2) (Metric Units)
BMI = 703·weight (lb.)/height2 (in2) (U.S. Units)
