BMI--I've about given up on it. Every calculator I use, I put the same info in, and I get a different answer every time. If they're going to use BMI for insurance purposes, etc., then they need to make it consistent across the board. It's ridiculous.

    All the calculators I have used have always given me the same numbers. I am currently 25.02. So close to normal! :smile:

    It's standard. Use a calculator. Put in your weight in pounds. Divide it by your height in inches. Take that new number and divide it by your height in inches. That that number and multiply by the magic number 703. This works really well for folks who are outside of a printed chart.

    Thanks for the info cbelc2. I downloaded a couple of apps and they must just be really bad ones. At least they were free. :)

    It's not a joke. What percentage of the people listed as overweight according to BMI are overweight because of muscle mass? Not very many

    After a little more playing around with it, the issue is that they're all giving me the same NUMBER, but whether they classify it as overweight or obese seems to vary widely. On one site, it says that at 182 and 5'4" I'm obese, while another says overweight. My goal weight is 145, and one site says that's still in the overweight category, while another says that 151 will put me in the normal category. Whose chart to trust...?

    Yeah you do not have high body fat but using the formula you are overweight and it is likely lbm.

    What us gonna do. BMI is a good population guide and for joe blogs is good. If you've built a substantial amount of muscle weight though it ain't going to fly.

    However any doctor would just need to look at you to understand you are an outlier and that is the point of BMI really. To establish if further investigation (I.e show me your belly sir) is required.

    I'll be still in Overweight when I reach my goal weight. I have a large frame http://www.myfooddiary.com/Resources/frame_size_calculator.asp

    The only time I was in Normal was after 6 weeks of under-eating and over-excising during boot camp.

    While I think BMI is useful for generalizations about populations, there will be individuals for whom it does not work.

    The one the NIH (National Institutes of Health) uses would be the one to go by.
    For 5'4:
    174.6 lbs or higher = BMI 30 + /Obese
    145.5 - 174.5 lbs = BMI 25 to 29.9 / Overweight Range
    107.5 - 145.4 lbs = BMI 18.5 to 24.9 / Normal Weight Range

    I'm guessing the one you stumbled across that said 145 is overweight is probably the adjusted one for Asians. That BMI chart has the normal range stopping at a BMI of 23.

    No it doesn't. 145 puts a 5'4 person at 24.9 which is the top end of the healthy range.

    My doctor wasn't joking when she told me my BMI was almost in the obese range. I scoffed at this for 2 years, then decided she was right. Now it's 24.5 so I'm sure she'd be happier with that number. I know I am. I thought maybe I was an outlier as well, but I was just lying to myself.

    I always use the calculator on the Canadian Diabetes website. It was the first result when I Google it and since it's the CD site, I trust it.
