what causes obesity
The definition of overweight or obese varies widely, but in general obesity is excess body fat experienced by a person chronically. In normal conditions, the body fat serves as an energy reserve, regulating body temperature, protection from trauma, etc.. Ideally, a woman 's body is composed of 25-30% fat, while 18-23% fat in men. When body fat exceeds 30% in women and 25% in men, then that person can be considered overweight or obese. The easiest way to determine the level of obesity is to find the value of BMI (Body Mass Index / Body Mass Index). BMI is calculated by dividing weight in kilograms with height in meters squared.



Here is a BMI assessment scale :
BMI < 18.5 : Underweight
BMI 18.5-24.9 : Normal
BMI 25.0 to 29.9 : Overweight
BMI 30.0 to 34.9 : Obesity class I
BMI 35.0 to 39.9 : Obesity class II
BMI > 40.0 :  Obesity class III

The higher the BMI, the more overweight a person is classified, and the more fat, the higher the risk of some dangerous diseases, such as coronary heart disease, hypertension, diabetes mellitus, cancer, gallbladder disease, stroke, osteoarthritis (arthritis), and gout (uric acid).
