The Body Mass Index Body mass index, or BMI, is a measurement that evaluates the relationship between body weight and height. While BMI is not a direct measure of excess body fat, it is the recommended method to diagnose overweight and obesity. Because it expresses the weight height relationship, BMI provides a more accurate measure than body weight alone. The formula for calculating BMI uses weight in kilograms and height in meters: BMI (kg/m2) = Weight (kg) Height (m) 2; or weight in pounds and height in inches: BMI (lb/in2) = Weight (lb) Height (in) 2 x 703. Online calculators that automatically do the computations from an entered height and weight are a convenient method of determining BMI. Over 50 healthcare organizations around the world, including the National Institutes of Health, use the same BMI standards to define adult overweight and obesity.1 BMI’s Link to Diseases BMI is used as the standard to diagnose overweight and obesity because there are so many studies that show a link between BMI, the risk of several diseases and death.2 As BMI increases, so does the risk for several conditions3, including Sleep apnea Some cancersWhile the links between BMI and disease risk is clear, it is important to remember that it is only one of several disease risk factors. In other words, BMI cannot tell an individual that he or she will get a disease, only that his or her risk of developing the disease is increased. BMI has some limitations.4 It tends to overestimate body fat in people who are very muscular and underestimate body fat in people who are highly sedentary. BMI also doesn’t show where the body fat is located. Abdominal fat carries the greatest health risk.
How Much Exercise Should I Do Daily to Burn 3500 Calories When you’re interested in tracking the calories you burn through exercise, you’ll often hear people discuss the 3,500 calorie threshold. However, this number isn’t representative of the calories you’re likely to burn during any exercise. Rather, it represents the number of calories in a pound of fat. It’s more realistic to burn 3,500 calories with exercise in a week, but not in a single day. Don’t Expect to Burn 3,500 Calories Daily Burning 3,500 calories daily in a workout is impractical to even attempt. A 175 pound person would have to run at 8 mph for more than

Set More Modest Goals Losing a pound per week which requires you to create a calorie deficit of 3,500 calories is a sensible weight loss goal.
