"This is the first installment in a series of discussions focused on health and wellness. During a yearly physical, weight and physical fitness may not be topics discussed in great detail with your general practitioner. It may be suggested that you need to lose a few pounds or work out aerobically three times per week, but how do you know the healthiest range for your weight? One method is to calculate your BMI [Body Mass Index]. The BMI is an estimate of body composition, specifically body fat. The normal BMI range is 18 to 25. A BMI below 18 is considered underweight and a BMI above 25 is considered overweight. A BMI over 30 is considered obese. Research has shown that keeping your body weight in the normal range reduces your risks of serious health effects like heart disease and diabetes."
