## Weight, Obesity, and BMI

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.

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?

Well I’m 11 5’0” and 115 lbs and people call me overweight if you think that your overweight then check this site and then you can shove it in there faces

@jackkson

Yes that is fine

@Raquel Minard

How dont you know bruh im 13 i weight more than you im 123

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

Im 12 yrs old, 5ft 8” and i weigh 151lbs. i do 5 sports and most of mt body is muscle is it bad that I weigh so much?

Actually I agree with the site I’m 6 feet and I weigh 134 pounds and I only need to put on 5 more

I’m 11 years old 5ft 6in and 120 lbs so I’m in aight shape I’m lifting and running for football to gain some weight and muscle

I am 15 I am 165 and 5″8 am I obese?

@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.

Is it okay if I am 13 years old and 6’7″ and I weigh 110 pounds?

@Grace</a

Sorry for replying a year later but in case you are still worrried yes it is obese and I would know because at age 11-14 I was very obese and I was around 5'4 and weighed around the 170s. I'm not obesed now thank God but really consider doing sports and eating less portions like eating only until your satisfied and not full. Hope this helps!

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.

if i am 5,11 and i weigh 140 is that normal

I THINK I’M OBESE BECAUSE I AM 5 FT AND WEIGH 120 – 130 LBS. AM I OBESE?

@blair godlesky

this doesn’t take into account bone density of muscle mass. purely bmi

i’m 12 and am 5ft 6 and am 121 pounds so i’m guessing i’m not overweight

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.

@clark

Muscle cannot turn into fat this is a biological myth

I am a 10 year old man who is 4’4 youre scale doesnt go low enough for me to see so Im goig to assume I am not boese. I only weigh 128 ponds.

Shaq was 440 at 7 ft not 300 like it says

I’m 6,9 But 15 I Weigh 240 And Im Pretty Skinny But That Out Of chart For 6,8 This Isn’t I’m Underweight if any but according to this I’m over get out of here

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!!!!

@Jane

Jane– Being anorexic is not “normal!”

@Grace

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.
