Calculate Body Mass Index (BMI)

First things first! Your Body Mass Index or BMI is supposed to be an indicator of how healthy your weight is by comparing it to your height. I say “supposed” because it is only a rough guideline and will not be accurate if you are super athletic and musclemanish, i.e. muscle weighing approximately 3 times as much as fat.

However, if you’re the average person, and like the rest of us blobs you eat when you’re hungry and exercise when you have to, and throw up on mom’s shoes after running 300 metres uphill before passing out… (hohoho poor lizliz ^^), then you’re good to use this means of “overweight”, “underweight” or “proper weight” estimation :)

So! The Imperial formula is as follows:
BMI = (weight in pounds * 703 )
————————————
height in inches²
And, here’s the metric one, if you are that way inclined.
BMI =
 weight in kilograms
————————————
height in meters²

*For those of you who are not so mathematically inclined, 1 meter = 100 cm and 1 foot = 12 inches.

And thus, Using our Imperial formula as an example,

  1. First, weigh yourself. Write down your weight in pounds. (For argument’s sake, let’s say you’re 100 pounds, you skinny creature.)
  2. Multiply 703 with your weight. (In this case, 100 x 703 = 70300)
  3. Measure your height. Write that down in inches. (For example, if you’re 5 foot 4 inches, you would have 5 x 12 + 4 = 64 inches.) Square it. (64² = 64 x 64 = 4096)
  4. Divide your weight figure with your height figure. (70300 ÷ 4096 = 17.16 which you would round up to 17.2)

To rate your BMI:
Underweight = 18.5 or less
Healthy weight = 18.5-24.9
Overweight = 25-29.9
Obese = 30 or greater

At 17.2, this would make you severely underweight, and you should eat more until you’re fat and happy. Hurray!

Remember, just because you happen to fall into the healthy weight category doesn’t necessarily make you healthy!! We all know those annoying people that eat nothing but junk food and drink buckets of lard all day, never, ever exercise, but won’t gain an ounce. Probably have a high percentage of body fat, but it doesn’t show and no one can tell, so they go around pretending to be skinny all day. Grrrr…This is what I term as the SECRETLY FAT phenomenon that I am OPENLY JEALOUS of. But more about that next time. Byebye!

p.s. If you’re lazy like me, forget the math and just use the calculator up thar. XD
