How do we judge a healthy weight range? BMI is no longer valid?

    ...Frank Zane, at 5'9'' was under 200 pounds when he won Mr. Olympia, just as a reference point.

    Also I too "easily" was around 195-200 pounds all my life. I didn't look fat, I was slightly chubby at most.
    Now I'm at 150, about 13% bf and feel like another 5-10 pounds down are totally doable before bulking for more muscle mass and all that while I'm a head taller than you.

    I'm thinking you're overestimating your lean mass or how normal you look like at a higher weight like was mentioned before, due to the unfortunate fact that obesity is so prevalent, it's becoming the new "normal" in perception.

    Also, while I'm glad that you've set a goal, met it and found
    another AND managed to belittle me in one post. I'll just go ahead and brag about a 150 meter sprint, hopping a 6 foot fence, getting punched in the face and pepper-sprayed before successfully wrestling someone who outweighs me by 50-60lbs to submission while wearing 30lbs of gear in 90 degree weather for fun. And got up for work the next day.
    I think you may also underestimate how abnormal Frank Zane and that ilk look.

    And if you're more into sprinting, take Usain Bolt. The world record holder is at just under a BMI of 25.

    Another simple way to measure heath would be to take a look at the waist/hip measurement

    http://www.topendsports.com/testing/tests/WHR.htm

    A waist to hip ratio greater than 1 is considered an extreme coronary health risk.

    I doubt any of us are here because our BMI's are 27 instead of 21. Use it as one input. Your eyes and your heart and your sports performance and your overall health are the best metrics when you get close.

    Didn't someone above just say she went from 27 to 21?

    30.4 when I was fat and had no illusion that I was "big boned" to 20.9 for my running race weight.

    I want to understand how to judge a healthy weight range for myself in order to take opinion out of the equation. What is the standard we are using now? I feel like BMI calculations are dated right? Is body fat percentage the best metric? What is the best measurement tool?

    What is the issue with the BMI? It was updated rather recently.

    The weight ranges were determined 240 years ago in France, which was in the midst of the Maunder Minimum famine. With that little historical semi-accurate nugget stated, I'll share that my Dr asked my loss target and I told her it was the middle of the healthy BMI for my height, which is about 160. She suggested that I should go no lower than the top of the healthy BMI for my height, which is about 180. My brother is my height and he's always looked good at about 170.

    No, they were not. They were recently updated by the CDC. The WHO has another range they use, but it's pretty close to the CDC's.

    As a non-muscular woman, BMI has been spot on for me. I sit happily at the lower end of the BMI range - about 19/20 is good for me. I could gain another 30-35lbs and still be considered a good weight.

    In my biased, personal experience, I have never met someone in real life who decried BMI as unrealistic or unattainable who I didn't look at and think, 'hmm, I DO see where 10lbs could come off you'. Obviously where they maintain their weight is their decision, and I don't believe being a BMI 25 rather than 26 is going to overhaul anyone's fitness levels or long term health, but I do believe a lot of people consider themselves an outlier due to muscle/frame size or find it better to decide BMI is flawed, when really just as a country the UK is getting fatter.

    Case in point: we had our BMIs calculated at work as part of an occupational health day, and one of my colleagues received a measurement of 30. She was not happy with this and spent a good part of the rest of the afternoon telling anyone who would listen that she had a higher muscle proportion than most (a woman in her 50s whose only exercise, by her own admission, is walking her dog) and that BMI was 'dangerous' for women with hourglass figures to try and conform to.

    I've yet to meet anyone who I thought really probably was a BMI outlier.

    I consider myself muscular. I've even competed in a figure class bodybuilding competition (although I'm not muscular enough to be competitive). I have always fallen on the top end of the BMI. I can never imagine myself at the low end of the weight scale and I have been down to a lower body fat level.
    We did a health assessment at work before where I was just over the BMI into the "overweight" category. The nurse used the waist measurement as a second evaluation and classified me as "healthy". I wouldn't have considered myself as overweight but I did have weight to lose.

    TL;DR - I agree with you.

    One caveat about the thing with the belt, it can depend on how you wear your pants. The waist measurement for assessing body composition is supposed to be taken around the navel, whereas most men wear the 'waist' of their pants more toward the top of the hips. I wear size 36 pants, but my actual waist measurement is 47.5. Fortunately, my belly distension is not flabby, or I'd be sporting a major 'dunlap' aside from just being round.

    So basically what you are saying is- you are obese with an unhealthy amount of visceral fat and you have problems with your BMI.

    I'm saying I am obese and working on it, and BMI is completely irrelevant. Body Fat Percentage is a useful tool.

    Depending how you look at it. It could be "unfortunately" because a belly that is not flappy indicates a large amount of visceral fat. So basically in your case BMI is currently a good indicator of fatness, and the worst kind too.


    yes, at my current weight, BMI does happen to come out pretty close to my actual body fat percentage. If I get to my goal weight (220) without losing any lean mass, which would still leave me at the very low end of average muscle percentage for a male, my actual Body Fat Percentage would work out to just under 22%, where BMI would calculate to 29. In other words, BMI would tell me I was bordering on obese when I was at the high end of average for my age. This is why I say BMI is worthless for trying to determine an individual's ideal weight. Even if it were accurate, the weight ranges on the charts are too broad for one to pick and choose a goal based just on BMI, and how to determine ideal weight was the original topic of the thread.

    The one that uses wrist and frame size was also said to overestimate lean mass potential.

    Yes, but I highly doubt it's 50 pounds over.

    Try the others and see how different it is for you.

    And that guy is seriously -skinny-! A guy that lean works out to barely at the top end of "healthy" weight according to BMI, and you don't see a flaw in the metric? I mean, he's gotta be what, no more than 13% body fat, if that?

    Sorry, as has been mentioned before you are wearing size 36 pants because you have a large amount of visceral fat. The location of the fat forces your pants to fit that way. Most men don't wear a pants size 12 inches less than their waist size.

    I never claimed I didn't. I was merely pointing out that using your belt size as an indicator is not going to be accurate if your belly is larger than your belt. If I assessed myself based on my pants size, it would suggest I'm in pretty decent shape, which clearly is not the case.

    Since neither of us knows, let's assume 100 %.

    Do you think this world-wide conspiracy against meet is part of why people are so worried about carbs?

    Again, not a conspiracy, group-think. And low carb is very much counter to the "establishment" position. The agencies that push BMI still favor the low fat, high carb model.

    The parameters of the current BMI scale were set by the CDC, National Institutes of Health, and World Health Organization in the late 90's.

    Two federal agencies and the UN, there's a real model for trustworthiness.

    (do I need to tag the sarcasm?)

    Why are the CDC and NIH not trustworthy? Have they been infiltrated by vegans too? Is this a "it's the government so of course they're lying" kind of thing? Or just "their data doesn't support what I want to be true so I'd prefer to ignore it?"

    Lies and/or incompetence, take your pick. Govt in general can not be trusted with anything. Especially when talking about all these alphabet agencies who's existence is not even Constitutionally authorized.

    I mentioned it previously. I did try the others and they still gave me a total weight that was over 200 pounds at 15% body fat, where the BMI charts say I would be a 24.4 at 185 pounds. When a calculation shows that I have to shed functional muscle in order to reach a level where I'm considered to border on "overweight", there is something wrong with the references being used.

    Skinny?

    I was picturing the wrong guy apparently, I don't follow sports. But in any case, he is very lean and NOT carrying that much in the way of extra muscle. If he were actually at 25% body fat he would definitely look borderline overweight. In other words, your own example has demonstrated BMI as a crappy estimator of body fat.
