Calculate BMI (Body Mass Index)

9 posts in this topic

This script will calculate your BMI (Body Mass Index) among other things, a GUI will come shortly.

Thought I'd share an old script that was collecting dust. Original Author (javascript): http://home.fuse.net/clymer/bmi/

;Just change the variables appropriately. 
$nWeight = 150 
$nHeightFt = 5
$nHeightIn = 10
$nWaist = 33
$sSex = "m"
$nAge = 21

$arr = _BMICalc($nWeight, $nHeightFt, $nHeightIn, $nWaist, $sSex, $nAge) ; _CalcBMI(160, 5, 9, 36, 'm', 19) 
$arm = _BMIMsg($arr, $sSex)

msgbox(0,'', _
'Body Mass Index (BMI): '& $arr[1]&@lf& _
    @TAB & $arm[1] &@lf& _
'Waist to height (WtHR): '& $arr[2]&@lf& _
'Body Fat: '& $arr[3]&@lf& _
'Surface Area: '& $arr[4]&@lf& _
'Basal Metabolic Rate (BMR): '& $arr[5]&@lf& _
'Willoughby Athlete Weight: '& $arr[6]&@lf& _
'Willoughby Athlete Waist: '& $arr[7]&@LF)


Func _BMIMsg(ByRef $aArr, $sSex, $Ext = 0)
    Local $aArray[8], $sBMIText[8][8][8]
    
    $sBMIText[1][1][1] = 'Underweight.'; The lower the BMI the greater the risk' 
    $sBMIText[2][1][1] = 'Normal';, very low risk'
    $sBMIText[3][1][1] = 'Marginally overweight';, some risk'
    $sBMIText[4][1][1] = 'Overweight';, moderate risk'
    $sBMIText[5][1][1] = 'Severe overweight';, high risk'
    $sBMIText[6][1][1] = 'Morbid obesity';, very high risk'
    
    #cs
    A BMI from 20 through 26: desirable for most middle-aged adults. 
    Nonsmokers with a consistent BMI within this range have the lowest risk of disease and premature death. 
    In this category, weight gain can be avoided through moderate eating habits and exercise.

    A BMI from 27 through 29: moderately overweight, carries a slightly increased risk of weight-related health problems, 
    such as high blood pressure, high blood cholesterol, heart disease and adult-onset diabetes. 
    People in this group have the hardest decision to make about reducing, given the potential health risks of weight loss. 
    To prevent the development of weight-related health problems, most people in this category should avoid gaining additional 
    pounds by adopting a low-fat diet and a routine of regular exercise. Weight loss for cosmetic reasons is very common here.

    A BMI of 30 through 40: truly overweight, the risk of developing heart disease and other weight-related conditions rises sharply.
    Most people should lose weight in this category. Adult-onset diabetics in this category should definitely reduce,
    since blood-sugar control improves with weight loss.

    A BMI of 40 or more; severely overweight, you are in great danger of dying early. 80% eat in frequent binges. 
    Secret eating is common. Best weight loss technique is often a fasting diet. Benefits of losing weight clearly outstrip any dangers.

I created a nice BMI chart here, maybe you can get some ideas:

Uh, no... With a BMI of 40 or more, that eating isn't secret anymore. :mellow:

Neat script! Throw together some more health related calculations, maybe a calorie tracker, and you could have a saleable program :(

Is this really working ? I'm 96 KG and it says that i'm underweight and BMI : 0

Edit : ..

$nWeight = 96

$nHeightFt = 5.544608333

$nHeightIn = 66.5353

$nWaist = 40

$sSex = "m"

$nAge = 15

@weaponx

Thanks for the script, I will surely use that.

Edit : ..

The weight is calculated in pounds. :mellow:
