Last blog post I talked about BMI or Body Mass Index to determine a person’s health in relation to the growing obesity epidemic.
BMI is calculated using your weight and height (your weight divided by your height squared). There are a number of websites that can easily provide you with your BMI. Here is a couple of links;

The problem with BMI, is that even though you may have what's considered a healthy BMI - let’s say a BMI of 20 to 22, the body mass index doesn’t take the composition of the weight into account. For example, bodybuilders are heavy for their height and will have a high BMI.
The World Health Organization defines obesity as a body fat percentage over 25 percent in men or 35 percent in women. At a BMI of 25, which is considered just barely overweight, this would be incorrect as it doesn’t take into account the body fat percentage.
Along with BMI, a person’s waist circumference should be looked at. According to Dr. Michael Greger of Nutrionfacts.org, someone with “normal-weight central obesity,” meaning someone not even overweight according to BMI, but fat around the middle, may have up to twice the risk of dying compared to even someone who’s obese according to their height and weight!
Increased risk of metabolic complications starts at an abdominal circumference of 31.5 inches in women and around 36 inches in men.
According to Dr. Greger, the good news is the riskiest fat (visceral fat) is the easiest to lose. If you are severely obese, you may have to lose 20 percent of your weight to realize significant improvements in quality of life. However, for most, just a 5 percent weight loss (just 10 pounds for someone weighing 200 pounds), blood pressure and cholesterol improv cutting your risk of developing diabetes in half.

Next time I will be discussing tips to losing that visceral fat.
