N: 1. overweight (adj.): “in excess of proper or ordinary weight,” 1630s, from over- + weight (n.). Of persons, as a noun, “obesity” from 1917.
2. An excess of body weight but not necessarily body fat (characterized by) a body mass index of 25 to 29.9 kg/m².
3. overweight: This term, which refers to an intermediate weight category that falls between normal and obesity, is also used to refer to the condition of any person whose body mass index is more than 25 kg/m², including obesity.
4. Overweight and obesity are defined as abnormal or excessive fat accumulation that presents a risk to health. A crude population measure of obesity is the body mass index (BMI), a person’s weight (in kilograms) divided by the square of his or her height (in metres). A person with a BMI of 30 or more is generally considered obese. A person with a BMI equal to or more than 25 is considered overweight.
5. Overweight and obesity are major risk factors for a number of chronic diseases, including diabetes, cardiovascular diseases and cancer. Once considered a problem only in high income countries, overweight and obesity are now dramatically on the rise in low- and middle-income countries, particularly in urban settings.
