Weight, Obesity, and BMI

April 25th, 2008

Did you know 1 out of 3 Americans is obese? 2 out of 3 are overweight? Yep, according to a 2007 CDC study. And according to a 2007 worldwide study, 40% of adults are overweight, with 25% being obese. Holy crap. More people are obese than underweight worldwide (WHO 2000). And don’t forget the childrens – 15% of those ages 6-19 are overweight according to 2000 CDC data, triple what it was in 1980 (more stats).

But how much do you have to weigh to be considered obese? Well, you are considered obese if you have a BMI greater than 30, and overweight if its greater than 25.

What is BMI? Body Mass Index. It’s the most popular, accurate way (heh, way, pun) to measure obesity (sort of). It’s a simple formula based on your weight (lbs or kg) and height (inches or meters). According to CDC, the BMI formula is 703 x (lbs) / (inches^2), or if you are from metric land, its just weight (kg) / [height (m)]2. For me, I have a 23.7 BMI, thats 703 x 175 lbs / (72 inches)^2 = 23.7, or 79.4 kg / (1.83 meters)^2 = 23.7 in metric talk. Heres my BMI results from this BMI Calculator, which gives you a nice chart like this:

BMI Weight Range (6′ tall) Weight Status
18.4 and Below 135.7 lbs and Below Underweight
18.5 – 24.9 136.4 – 183.6 lbs Normal
25.0 – 29.9 184.4 – 220.5 lbs Overweight
30.0 – 34.9 221.2 – 257.4 lbs Obese (moderate)
35.0 – 39.9 258.1 – 294.2 lbs Obese (severe)
40.0 and Above 295.0 lbs and Above Obese (very severe)

If you’re 20 years or older, its the same for men and women. Here’s a BMI Calculator for those under 20. If you ain’t feeling this math or the BMI thing, don’t worry – I crunched the numbers and made this reference chart.


Weight Chart, Over 20 years old

Height Normal Weight Range Obese
5 ft, 0 inches 94.7 – 127.7 lbs 153.3 or more
5 ft, 1 inches 97.9 – 132.0 lbs 158.5 or more
5 ft, 2 inches 101.1 – 136.4 lbs 163.7 or more
5 ft, 3 inches 104.4 – 140.8 lbs 169.0 or more

5 ft, 5 inches 111.1 – 149.9 lbs 179.9 or more
5 ft, 6 inches 114.6 – 154.5 lbs 185.5 or more
5 ft, 7 inches 118.1 – 159.3 lbs 191.2 or more
5 ft, 8 inches 121.6 – 164.1 lbs 196.9 or more
5 ft, 9 inches 125.2 – 168.9 lbs 202.8 or more
5 ft, 10 inches 128.9 – 173.8 lbs 208.7 or more
5 ft, 11 inches 132.6 – 178.9 lbs 214.7 or more
6 ft, 0 inches 136.4 – 183.9 lbs 220.8 or more
6 ft, 1 inches 140.2 – 189.1 lbs 227.0 or more
6 ft, 2 inches 144.1 – 194.3 lbs 233.2 or more
6 ft, 3 inches 148.0 – 199.6 lbs 239.6 or more
6 ft, 4 inches 152.0 – 204.9 lbs 246.0 or more
6 ft, 5 inches 156.0 – 210.4 lbs 252.5 or more
6 ft, 6 inches 160.1 – 215.9 lbs 259.1 or more
6 ft, 7 inches 164.2 – 221.4 lbs 265.8 or more
6 ft, 8 inches 168.4 – 227.1 lbs 272.6 or more

Notes:

I’m not sure I trust CDC entirely. This 2006 CDC study said no change in American obesity since 2003-2004. But by their own numbers, obesity went up 2% overall, almost a 7% increase (males up 7.1% from 31.1% to 33.3%, females up 6.3% from 33.2% to 35.3%). At that rate the number of obese people will more than double in 11 years. Yes, no-increase means double in 11 years. Hello? Is this the new Bush-Era Science?

    i am a 25yr old female, 5’6, weight 118llbs. Although i am on the low side of the ”normal” weight listed above i am still very curvy and not ”too skinny” by ANY means. my husband is 31, 6’3 and weighs 225llbs and i think thats ideal for his height. i think the grey area in the chart should be further explored. we are very athletic and left heavy 5 days a week. i do although believe there is a difference for men and women and for individual body types that wasnt explored in the above chart

    @Stephen ray powell
    Obese is considered a form of being overweight, so I guess the website means that the same amount of people are obese as overweight, which does seem off. However, it does account for people who are not overweight with the 1 in 3.

    Seriously? My husband is 5 feet 11 inches tall. According to this chart he should be at 132 minimum? Someone must have been drunk when they made this chart. At 132 he should look sick anorexic. My husband weights 224 and no one tells him he looks fat or anything he looks really good at that weight. Well he works out daily. In lifting and running. His muscles you can see them that has put some effort into having them. They are not full muscles but you can see the markings. Thats why it might explain the weight at 224 but at 132 is WTF.

    In short be yourself be happy. Just be you. No chart like this will make you happy and i think this chart is totally wrong.

    You’re all American and really have had your ideas on a “healthy looking size” screwed up by 50 years of gradually burgeoning wastelines. Inventing a new normal doesn’t solve growing health issues

    @Tony
    Depending on your bmi six feet tall should be between 136 and 183. So your probably on the upper bmi if you looked skinny at 160. not everyone’s body who is 6 feet tall is the same some 6 feet tall ppl will look a little chubby at 160.

    Ridiculously low weights on the low side. Isn’t there something unhealthy about having almost ZERO MUSCLE? A male 6 foot and 140 lbs would be a stick! Just another game by people in charge to generate money and hype. I’m 6’3″ and 220. I could lose 5 lbs – NOT 50!!!!

    Hey buddy. You’re too young to worry about your weight. Your body is still growing and you need those building blocks to form a strong skeleton and adequate muscle mass. Do yourself a favor: go find a workout program that focuses on total body health, like crossfit or a high school lifting program. Doing so will bring your weight to a level that is right for you, while encouraging your body to build balanced mass. You’ll feel more confident and worry less about your body weight.
