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, 4 inches 107.7 – 145.3 lbs 174.5 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?

    Got to watch your weight! Not only for the sake of being healthy but it can also mess with you in other ways. My Insurance Expert told me I could have fallen into a better plan if I lost some weight. It wouldn’t save me tons of money and make me rich by any means, but saving is saving.

    im 6 foot 3 inches and also a bean pole how am i class 1 obese? i weigh 242 and im obese?! im tall and bone like nothing jiggles so how the hell am i obese?! please answer this….for i am confused

  5. July 28th, 2015 at 21:48 | #5

    Too be quite honest I am built rather stocky and if I was in the weight it says I should be I would look like bone I am nearly six feet and overweight but not obese and it says I should be 7 or 8 feet to not be obese… This probably applies to a skinny build wrap your index finger and thumb of your non dominant hand around your dominant(writing hand) wrist and if your fingers overlay your a skinny build… If your fingers touch or barely touch your medium build… If they don’t touch or are nowhere near touching your stock built like me… So it does matter on your build hope this helps

    It’s impossible that a 6’7 young male’s highest weight should be 221.as a normal weight and that 265 is overweight . My son is a 6’7, 300 lb . football player and in 11th grade. No one has ever said nor does he look overweight. However at 221 he would look anorexic. Certainly bone structure must factor into this somehow.

    Yal people that work out in the gym a lot can be just as unhealthy being 6 ft 210 lbs of muscle mass. More power to you if plan on doing work out plans same from when your 20 to your dead. Other wise all your muscle turns to fat… I agree in being healthy but not with weights and bulking up to look like Roman carved statue. .. just kyak walk run swim stay active you will be alright.. I assume all yal people confused work with weights every day

    As guy who is 190 and 6’8″ I can see how this is confusing. It really has to do with fat ratios. If you are 6′ with 20% fat obviously that’s bad. I’ve been as high as 245 but that wasn’t healthy either because I didn’t build any muscle with that weight

    well I’m 6’0 and 205 but i currently goto the gym and am going until i get to 170 so i guess I’m in shape, but i just turned 20 1 and a half months ago so I can definitly lose 30 pounds in a month if i work my ass off but thats only because I’m young so i better do it now before I’m 50 and I’m old and get to the point where i want to lose 10 pounds which will take months for a 50 year old lol

    Muscle weighs more than fat. You could be pure muscle and be considered obese.

    That’s is the silliest thing I have ever heard. Yes cardio is needed but muscle does not turn to fat if you are someone who continuously works out. As you get older if you up your cardio and eat healthy it ain’t turning to fat. I lift every day and skate and kayak and hike and run … Building lean muscle daily … Prolly look a lot more in shape than you now at 25 and will when I am 65 you have too be well rounded. @clark

    OK. So I’m a 11 year old girl and I’m 5 ft. tall. So what is average weight for my height and average? So could someone please answer my question? Because school is about to start and I’ll be in mid school (I’m young to be in mid school), the worst time to be cubby. And since I’m going to be a mid schooler, I’m aloud to priticipate in sports and I really want to play basketball. But if I’m not in shape, I can’t. I also don’t want people laugh at me.

    Collin my nephew is just turn 23 in May. He is 6 ‘ 8 1/2″ and he been since he’s was in the 7th grade. He of course hated being that tall so young but he wore a size 28 ,29 waist. 36 length.Try finding those bad boys off the rack. However he went into the navy he put on weight and I don’t know if he is even over 200 lbs now but his waist went up to a 32,34. He looks healthier than he ever has. Now he thinks he’s fat. He’s not even close. I myself am now 52 and when I got married at 23 I weighed 105 and thought I was fat now i weigh 180 . Nobody believes me till I step on the scale. I’m now 5 ft 2 1/2 now I lost 1/2 in due to spinal neck fusion. I weigh way more now than I ever did pregnant all three times. I went into the army at 18. I was one of those who but on weight of course muscle weight. My son just turned 17 .He didn’t hit 100 lbs until he was almost 16. Dear Jesus I thought he won the lottery. He was around 5’ 3″ until he actually just hit a growth spurt now he is almost 5 ft 7. My girls are much older 29 now and 26. They were tiny and still are. The Dr’s worried about Their growth until I explained to them that there father was only 5 ‘6″ So by their calculations none of my children should have been taller than 5 ft 2 in. Well my 29 year old is 5 ft 7 1/2. Like I stated my now 17 year old is already 5’ 7″ and it’s all he can due to stay over 100 lbs. He’s definitely not a couch potato he’s and outside kid by choice as we’re his sisters. My point is weight and height is being measured on ” average ” there is no longer average. I think as long has your blood pressure is fine your cholesterol is good your not diabetic an healthy why does everyone feel the need to live in side the parameters of what is considered average. I would like to know how they come up with average now days cause I see no such thing. I do think back in the early 1900s late 1800s that people were more symmetrical if you will. Now I think it a bunch of B.S.
    I am just putting in my 2 cents. I was a LPN and An EMT. So I do have some medical back ground
    I just think average definitely died in the 20th century ;). Thanks

    Hey Rob lol we 50 years Olds can still read with reading glasses. I think I could take off 50 lbs at 52 that would mean I’m sick sick sick. I barely eat as it is but your 100 percent correct. Maintain long as your happy and can cause once you hit 50 it like you don’t even know who’s body your in. No disrespect intended just poking at ya. Thank you Linda

    Have they actually measured your legs separately. Start at your hip joint hold your foot straight up then Measure . Just make sure by you feeling the socket and ball in your hip and measure exactly from there to your heal. To see if they are both the same length…

    I am a 6’8″ Hispanic male who weighs about 300 pounds, but I do not work out or play sports anymore since I recently graduated from high school. I am by no means fat. I am built like a lumberjack. This chart seems to have a few things a little bit off if 227.1 lbs is overweight for this height. I feel like being that weight at that height most likely means that you are underweight. I have never heard of such obscene measurements. I don’t think anyone is that weight at 6’8″, unless they are anorexic.
