    The BMI scale is a joke. And this thing doesn't even take your height into consideration. I will put very little stock into what is says.

    Am I missing something?

    From what I see, the calculations assume that you already know what your current body fat % is, then uses that knowledge to calculate using a target body fat % to know what kind of actual poundage you should/can lose reasonably.

    The point is to do this based on body fat % rather than just blindly throwing a weight loss number out there that you think is desireable, but which may actually be detrimental if you are determined to lose it, regardless.

    Yet I see lots of people saying it's telling them what their current % is. Either I am misinterpreting it, or some of the other people are.

    There's a link at the bottom of the page that leads to the equation for figuring your % body fat.

    Well, I was just looking at the page that was originally linked, so I wasn't aware they were going to another link.

    According to that other link (to the actual body fat calculator), I would be about 26.33% bf. That's close to what I visually assumed I had, accept I was thinking more along the lines of 27-28%.

    Hmm, I'd like to be around 20%. I have a ways to go yet.

    BMI Formula:

    Weight
    _______ X 703

    Height in inches x Height in inches


    Scale weight is divided into two categories. Pounds of fat and Pounds of lean body mass

    Weight x Body fat percentage = Pounds of fat
    Weight - Pounds of fat = Pounds of lean body mass

    I already knew what my body fat was from when I joined a gym over the summer (not much has changed unfortunately...) but I was really shocked when I stumbled upon this and realized that 160 lbs, for me, means that I'm fit (22%), and that 145 lbs (12%) is unrealistically low for my level of dedication.

    Hey - I have put together a calculator based on the original webpage that started the discussion. Does the math to determine your reduced weight based on knowing your body fat % and weight. I haven't added in the calculation for body fat yet because I can see there is a lot of discussion on if it is correct.

    My speadsheet is a google doc here - https://docs.google.com/spreadsheet/ccc?key=0AsUGNe6xaFyVdHBQR2VDdW1NcndPQno3YXJwU3dnb0E

    Here is a simple body fat calculator - that I'll work in - http://www.scientificpsychic.com/fitness/diet.html

    Thanks for that post, it was helpful. Now.... if I only knew my current body fat percentage.

    Anyone know if the digital scales that measure body fat are accurate?

    I think the digital scales are out to lunch...i did the calculations on the website and apparently I have @27% body fat and my scale says 45%.....

    Huh -- the BMR calculator that site links to sure gives me a different BMR than the calculator on here does (when you set your goals) -- according to that website, MFP is overestimating my BMR by about 500 calories a day! Wow...I wonder which is more accurate.
