Overweight



Overweight refers to an excess of body weight, but not necessarily body fat. Obesity means an excessively high proportion of body fat. Health professionals use a measurement called body mass index (BMI) to classify an adult’s weight as healthy, overweight, or obese. BMI describes body weight relative to height and is correlated with total body fat content in most adults. But an easy way to determine if you are over-fat is to see how much body fat you have by pinching your skin fold. If you can pinch more than an inch of abdominal body fat, chances are you have too much body fat, and need to lose some. Also note that for people who are athletic with more muscle, especially people who lift weights (resistance training), the BMI will probably overestimate your level of fatness. It is best to get your body fat determined by a training individual for best results.
To get your approximate BMI, multiply your weight in pounds by 703, then divide the result by your height in inches, and divide that result by your height in inches a second time. A BMI from 18.5 up to 25 is considered in the healthy range, from 25 up to 30 is overweight, and 30 or higher is obese. Generally, the higher a person’s BMI, the greater the risk for health problems, according to the National Heart, Lung and Blood Institute (NHLBI). However, there are some exceptions.
For example, very muscular people, like body builders, may have a BMI greater than 25 or even 30, but this reflects increased muscle rather than fat. It is excess body fat that leads to the health problems such as type 2 diabetes, high blood pressure, and high cholesterol.
In addition to a high BMI, having excess abdominal body fat is a health risk. Men with a waist of more than 40 inches around and women with a waist of 35 inches or more are at risk for health problems.
Healthy Weight: BMI from 18.5 up to 25 refers to healthy weight.
Overweight: BMI from 25 up to 30 refers to overweight.
Obese: BMI 30 or higher refers to obesity. Obese persons are also overweight.
