As always, follow the money. And lately, the lust for power.
It’s built off the same bullstalin that gave us “somatotyping” which said that there were ideal body shapes/proportions and that non-ideal types might indicate certain behavioral flaws as well (withdrawn, etc.).
Should men and women weigh the same? No accounting for muscle vs. fat?
It’s an “easy” calculation but as bogus as the grain heavy food pyramid we saw under Herr Clinton.
For that reason alone, BMI is not very accurate.
Short people can be quite pudgy and have a satisfactory BMI.
Tall people can be beanpoles and have an unsatisfactory BMI.
If you are interested, have a professional measure your body fat (calipers are fine), which is what BMI is estimating. However, I’m not sure which direction is better in times of unrest. In extended times of unrest, a little extra body fat can carry you through lean times on limited food. A little extra body fat can also slow you down in case of violence. Look at how you plan to live in case of unrest and choose accordingly, but don’t assume there is a single right answer.
Well except maybe the guy on the left and the guy squatting, they according to the BMI index are just borderline obese.
The best way to determine if you need to lose weight is to look in the mirror. BMI doesn’t take into account bone or muscle density and thus can give false impressions.
BMI is useless. Eat healthy, exercise, sleep plenty, don’t drink or do drugs, and look good naked.
As I said, at my most athletic (6 minute mile), I was borderline “overweight.” I’ve always suspected that this metric is bogus, but just wanted helpful input here. Thanks.
It doesn’t factor in body structure. Most athletes have high BMI’s.
Take the BMI chart with a grain of salt, as a basic reference. Focus your attention on your waist size at the level of your belly button and see how much you can reduce that number.
I've been doing the same. Results come a lot slower now than they did in my testosterone fueled youth.
BMI is so blatantly stupid it’s hard to believe any medical professionals accept it.
First clue is a man and a woman of the same height are supposed to have the same weight. Duh! That exposes it immediately.
And anyone in very good shape with a lot of muscle is obese or way obese!
I was at 6-6, 213 and my BMI was 24.6, right on the edge of overweight. That was insane, I could exercise for five hours straight and had a 10-inch drop from my chest to my waist.
Agree. Not taking sex and build into account invalidates it for me completely.
The ‘B’ in BMI should stand for Bull$&it! Im 63 and 270lbs. I bench press 495, ride a couple hundred miles per week on my bike and eat no carbs or wheat products. Yet, Im morbidly obese according to the BMI charts. My body fat percentage would make a lot of people blush!
For the average person, its a fairly good guide. For people with a lot of muscle mass, not so much.
LOL! I know what you mean.
Try calculating what your weight should be for the middle of “normal” and let me know. I haven’t weighed that since the 6th grade!!!
I wonder if any FReepers would be interested in doing a weight loss group on here. A little mutual support / competition can be helpful.
If you wear anything over a size 0, you’re overweight these days.
Oh, the weapons angle is well covered. But endurance requires a trained, healthy body.
Even expert marksmen work out.
A few years ago, lean and mean and running a lot before my now-68 yr. old knees gave out, and lifting weights (41” chest, 32” waist), with hardly any real fat on me, my BMI was 26.25.
Supposedly, I was overweight.
Yeah. Maybe 1 lb.
Since I'm in the midst of mine, I'm game. I'm trying South Beach, which has really been effective on the weight side. Not as radical as Adkins, and not as boring either.
There’s different situations for not having a firearm in the home. I’m in Brooklyn, NY and have no means of moving to a more freedom-oriented state and town.
Completely unreliable. The basics for it come from the same set of scientists trying to “prove” the same things as phrenology. Why modern scientists picked it up is kind of inexplicable, but it’s a silly idea.
Try calculating what your weight should be for the middle of normal and let me know. I havent weighed that since the 6th grade!!!
I would need to quit lifting, quit eating, and dehydrate myself like a prune in order to make it to median normal. I wrestled 189 and 198 in HS, and I had to cut over 20 lbs to make weight each season - and it wasn't fat! Gym rats unite - the BMI is absurd!
I’m considered to be high normal. I think the BMI does not distinguish fat from muscle and bone.
I wish I was as fat as these guys.
Especially Apollo Creed...
Yes, BMI is seriously flawed as it is used today. The equation to calculate BMI is the work of a man named Ancel Keyes. Keys (ahem) borrowed the work of a 1800s-era Belgian mathemetician, where the formula was to be used in studying large populations. Keys’ graduate studies also involved sizing the total of fishery catches by measuring length and girth of individual fish.
You see where this is going?
We are not fish, and there is considerable variance across the breadth of humanity. Using BMI as a ironclad diagnostic tool when applied to individuals borders on quackery.
Here in MD, the Johns Hopkins group is slavishly devoted to BMI. It’s as if their doctors are required to bow and genuflect at a little shrine to Keyes before they begin their rounds.
This Keyes fellow is certainly a mixed bag. He is purported to be the inventor of the K-Ration, named after him.
Using BMI, most safeties and running backs in the NFL are obese, or close to it. BMI is garbage for people who lift weights.
Something funny about the picture I just noticed.
Arnold while being a big muscular guy is actually kind of short at only 5’7”. The other guys are all likely well over 6’
Look closely, the picture is taken on a hill and Arnold is standing back and up it in order to make himself (the star of movie) appear taller than everyone else.
He’s so far back you can’t see his legs & feet between the other guy in front of him (who no doubt was put there and squatting precisely to hide Arnold’s diminutive statue).
Well, I was at his inauguration for Governor and my recollection was that he was taller than me and I’m 5’-9”.
When you buy a pair of pants, is the waist measurement larger than your inseam? If so, lose weight.
That is a good idea. I was really fat, but started a diet and as of now I have lost exactly 100 pounds, 30 pounds left to go but they are going to be a b#tch.
I don’t know about that. I’m a 32-30 and need to gain weight if anything.
Well done! I have about 30 to lose too. I lost them last year but I “found” them again after I started a new job.
Weak, sickly, emaciated populations provide less resistance to the progressive takeover of your liberty and wealth.
so, I'm not overweight, I'm undertall.
He was amazed at how small Arnold was. The film editors must've had to work overtime to project his larger than life persona.
BMI is the dumbest measure, ever.
I have about 9% body fat (you can see 8 abs). I have a 34 inch waist.
I also deadlift 495 for 3, bench 405 for 6, squat (ass to ground) 520 for 5, do 15 pullups no stop, and easily can run a mile in under 7 minutes.
I’m morbidly obese per BMI.
Arnold is 6’2”.
You must be thinking of Stallone.
Third from the left, standing, and far right both have mental BMI’s way beyond obese squared.
Congratulations! Obamacare will require that your BMI be reported to HHS every year to track you, and most likely you will be penalized for your fantastic health. Your doctor will be required track your success in reducing your BMI to their satisfaction, and report to HHS for further instructions.
Looks like Arnold has been lying about his height.
Just read where he more like 5’10”; at best.
The claims for Arnold’s Height on the internet range from 5’6 to 6’2
The Indian guy to the Left of him is 6’3” and Carl Weathers to the right is 6’1”
If you were to move Arnold “Down the Hill” he looks like he would definitely be a few inches shorter.
Jesse is 6’5” I guess that’s why he at the bottom of the hill
Like I said, he was definitely taller than me.
