Your body mass index or BMI carries important information that you have to understand, as it does dictate possible health consequences you might face with your current weight. Apart from knowing your ideal weight, your BMI is something you should consider when you’re on an isogenics diet plan or any other fitness regimen.
A quick exercise in algebra
Don’t let the math in this computation scare you, it’s fairly easy to deduce your BMI. All you need to do is (1) multiply your current weight by 704, (2) square your height in inches, and divide the product of step 1 by the result of step 2.
Let us have an example: a man 67 inches tall weighing 188 pounds.
Step 1: 188 x 704 = 132352
Step 2: 672 = 4489
Step 3: 132352 ÷ 4489 = 29.48
A BMI of 25 to 29.9 means grade 1 obesity or being moderately overweight, like the man in the example. When your BMI reaches the 30 to 39.9 bracket, that’s grade 2 obesity or being severely overweight. A BMI of 40 and beyond is deemed massive, morbid or grade 3 obesity.
You could easily reverse the equation to find out your ideal weight. Input your desired BMI and multiply it by the square of your height before dividing it by 704. Applying the same parameters as the man in the example above, here’s the equation:
(24 x 4489) ÷ 704 = 153.03
From the initial weight in the example, the man has to lose 35 pounds to achieve the desired BMI.
Why bother with BMI?
Many associate high BMIs with arthritis, as people who have a high BMI at a young age are at greater risk of developing the condition later on. This doesn’t include the other possible surgical and medical procedures you’d go through such as knee replacements and medication that obesity brings. Excessive body weight can also complicate the success rate of these procedures too. These are the reasons those who want to get fit have to take their BMIs into account.
Obesity has a lot of medical conditions associated with it. In your muscular and skeletal systems alone, you could suffer different bothersome aches and injuries. Your BMI, then, is a good indicator of whether or not you should step up on your fitness plan or cut back a little to maintain your ideal weight.
