So before I share my thoughts, let's start with the science:
According to the Centers for Disease Control & Prevention (CDC):
Body Mass Index (BMI) is a number calculated from a person's weight and height. BMI provides a reliable indicator of body fatness for most people and is used to screen for weight categories that may lead to health problems. BMI is used as a screening tool to identify possible weight problems for adults. However, BMI is not a diagnostic tool. For example, a person may have a high BMI. However, to determine if excess weight is a health risk, a health care provider would need to perform further assessments. These assessments might include skin fold thickness measurements, evaluations of diet, physical activity, family history, and other appropriate health screenings.
The Metric Calculation for BMI is your weight in kilograms divided by your height in meters squared: xx(kg)/[xx(m)2] [shout out to all my international readers!]
The American Calculation for BMI is your weight in pounds divided by your height in inches squared multiplied by 703: xx(lbs)/[xx(in)2]x703
or you can skip this trip down middle school algebra lane and use a BMI calculator like this
...So what's my BMI?
weight: 116 pounds [yeah I'm not that girl who won't reveal her weight. I told people my weight when I was 134 pounds, I just don't care that much...] height: 64 inches [yeah...I'm vertically challenged, so what!]
*random math mumblings* [carry the 1...cross multiply 703...I really suck at math, lol]
OK, so what the hell does that number mean??
Well, the standard weight status categories associated with BMI ranges for adults are:
Below 18.5 Underweight
18.5 – 24.9 Normal
25.0 – 29.9 Overweight
30.0 and Above Obese
It's just that simple.....NOT!
What if my BMI isn't "normal" does that really mean I'm overweight?
Is there an ideal BMI or weight I should aim for?
Is BMI biased/skewed more toward those of European descent and doesn't factor in my ethnically influenced body shape and "shapely gifts"?
IMO, BMI generally does what its supposed to. The range in values for each category are fairly generous to allow for variations in body type and weight distribution, including some of those shapely "gifts from the motherland". Height and weight do have a strong correlation to your body fat distribution; if you're only 5'2" and weigh 150 pounds, the odds are, you truly are overweight. HOWEVER, that doesn't mean the system is perfect. Since BMI only factors in weight, and not body composition (ratio of body fat, muscle, and bone) it can lead some people astray. You need to first understand your body and be honest with yourself. If you have a naturally athletic/muscular build, and/or you're walkin' around all swole like Terry Crews or Serena Williams, you may end up with a 25+ BMI score, because muscle weighs more than fat.
|Damn, I gotta get my weight up!|
Big boobs and some extra junk in yo' trunk may also skew your BMI score, but if you have junk in yo' gut, thighs, arms, etc as well, then you could probably stand to lose a few pounds. Which brings me to my next point.
