N: 1. 1610s, from French obésité and directly from Latin obesitas “fatness, corpulence,” from obesus “that has eaten itself fat,” past participle of obdere “to eat all over, devour,” from ob “over” + edere “eat”.
2. Obesity, also called corpulence or fatness, excessive accumulation of body fat, usually caused by the consumption of more calories than the body can use. The excess calories are then stored as fat, or adipose tissue. Overweight, if moderate, is not necessarily obesity, particularly in muscular or large-boned individuals.
3. An increase of body weight beyond the limitation of skeletal and physical requirement, as the result of an excessive accumulation of fat in the body.
4. A popular technique for estimating body fat content is derived from one’s height and weight. This is called the BMI or body mass index. … Obesity is defined as a BMI greater than 30. As the BMI increases, so does the level of risk for health problems.
