Obesity, BMI and stuff

[chickenfeet]

I'm overweight but not by much. I weigh 213 pounds which at just over 6 feet tall gives me a BMI of 28.5. I would like to be 200 pounds (BMI=26.7) which would apparently make me still overweight. Frankly this is nuts. I was 200 pounds when I was playing rugby competitively and was as fit as I've ever been in my life. It's not like I'm unfit now. I've run 25km in the last four days which is more than a lot of people do in a year. What's really scary is that according to the BMI calculation I could be 140 pounds and still be a healthy weight! When I was ill about ten years ago I dropped to 155 pounds and I looked horrible, all skin and bone, and not in the least healthy.

So let's look at this in the context of the "obesity epidemic". It's trivially obvious that the BMI statistic exaggerates obesity among tall people and does the opposite for short people (weight, other things being equal, is proportional to the cube of body weight rather than being linear). It's a fact that in the developed world average height has been increasing for at least a hundred years. This of course means that obesity statistics based on BMI will get worse even if nothing is happening! I'm not saying there isn't a problem but it is being exaggerated by the use of a very dubious statistic.

You're in exactly the same boat as my husband -- he's 6'1", has a muscular build, is a runner, and weighs about 220. He's got some weight to lose, as we're both showing the effects of not-so-healthy eating, but if he gets much below 200 he starts to look unhealthy. But all the "experts" would tell him that he should be down to around 180 to be in the normal/healthy weight range. Bollocks.

For that matter, IIRC the *maximum* healthy weight recommended for women my height (5'3") is around 125. The last time I weighed that much, I was skin and bones. It's hard to gauge how much I should weigh, since I've put on a lot of fat as well as muscle over the last few years, but it's hard for me to imagine that I could look healthy at anything much below 140. (I clock in at around 170/175 now, which is morbidly obese according to the charts, but given that I don't even need to shop in the "women's" section in the store, that label seems misapplied. Yes, I'm too fat and could stand to lose at least 20lbs. But if I'm morbidly obese, then I don't know what to call larger people!)

hehe, I remember the women's section. That does amuse me that the Americans do that. I remember going over there and being about to look in the women's section and being grabbed back by my sister. Yet they also have size zero (UK 4????) - from one extreme to another

I've always been annoyed/amused by the "women's" section. On the one hand, you have society/advertisting/the media telling you that Real Women are thin. On the other hand, you have retailers suggesting that Real Women are, um, larger. Smaller-sized women's clothes are "misses." What is this all supposed to mean???

Kids' clothes are even wackier. Clothes for big girls here are often labeled as "Pretty Plus." Big boys' clothes are "Husky." It's all straight out of 1952.

yes! Misses! And there's juniors aren't there? I couldn't work out what size they were meant to be, but I had to get a much larger one than normal. :(

[thidwick.livejournal.com]

Yep. Juniors are the odd sizes up to 15...so sizes 0,2,4,6, etc. are misses, while 1,3,5,7 are juniors. Makes *perfect* sense, huh? :::rolls eyes::: Juniors are intended to be worn by teenagers and other less curvy women -- they're cut *very* straight. I was never able to wear them -- I always had too much of a curvy shape, even when I was skin-and-bones thin. :-)

oh good! I ended up having to buy a 13?? I think it was, whereas normally I wear a UK 12 or US 8 - I was totally lost. Many thanks for the comrehensive explanation...these were hipster jeans, and as my hips are a good ten inches bigger than my waist/chest, that'd probably be why I needed to go bigger...

[jen-c-w.livejournal.com]

bugger. I mean my hips and chest are ten inches bigger than my waist, not my chest is ten inches smaller than my hips. That'd just be silly. On the other hand there's a damn fine pie shop on my way back from work, so it might start going that way...

Yeah! I was beginning to wonder whether you resembled one of those inflatable toys one can't knock over.

jen_c_w the weeble doll :(
Actually just had a pig out on Chinese with susanbiscuit so it's possible.

Also....women's sizes are often labeled with a W. So you don't just buy a size 20, you buy a 20W. My sister used to think that that "w" meant "wide." :-)
