Document Summary

Obesity is assessed by body mass index or bmi this is calculated by dividing weight in kg by height in m2. Healthy range for bmi is 18. 5-24. 9, there are different ways to assess composition as to percentage body fat. Overweight is defined as 25-29. 9, while obesity is > 30. Body composition may differ within this range and some people with a higher bmi may not be at added risk for chronic diseases (such as hulk hogan with a bmi of 30. 3). Bmi does not tell the whole story, we need a little more information than that. Health risks are increased when fat is stored in the abdominal region. Where your fat is deposited is dictated mainly by genes but can be influenced by stress, smoking, and alcohol use.
