I am pretty sure that the BMI calculator you used is, like stated above, strictly for statistical purposes. Your BMI isn’t a very useful metric for health or asthetics. For health, a true body fat measurement is useful adn for asthetics, well try asking folks, “Do I look fat?” BTW, DO NOT ask your significant other, if any, this question. That would only lead a horrible answer that you would find objectionable, whatever it is.)
These calculators are pretty accurate for me… I am female, 5 foot 7 inches, and 135 pounds, 24-inch waist, wear a size 6 or 8 jeans. I consider myself to be normal, but not skinny.
From this site http://www.halls.md/body-mass-index/bmi.htm, for my height and weight I get this:
BMI 21.1 - In Normal Range
Your weight is at the 21st percentile according to your age and height.
Peoples Choice Ideal Weight: 130
Medical Recommendation: 121-160
So I guess I could lose 5 pounds to fit the “peoples choice” and 15 pounds to stay within normal range. Although if I lost 15 pounds I think I would be almost too skinny.
(By the way, considering that 2 years ago, I was a very chunky 198 pounds, hearing that I am in normal range makes me very happy indeed!)
I’m 5’9" and it says at 169 pounds I’d be considered “overweight.” I was skinny as anything throughout high school at 170. While there’s no question I need to lose weight — and I’m working out toward that very goal — this isn’t a reliable index for performance.
I have a BMI of 26.1 (just a hair on the wrong side of “overweight”). Having once weighed 334 with a BMI of 47.9, ask me if I care if I’m “overweight”
