Created in 2017 a NodeJS NPM module to use the Mifflin Fitness Macros into a return value.

You can find the NPM link in the buttons above or use npm to install with terminal/NodeJs and NPM:

Run in terminal

npm i fitness-macros-calculator

Test values

var mifflin = require("fitness-macros-calculator"); 
var sum = mifflin.macros({weight: 132,height:{ft:6,in:1},birthday:481834906});

The test will return

return value =  { 
     carbs : { weightloss : '137.0', weightmaintain : '218.0', weightgain : '259.0' }, 
     calories : { weightloss : 1291.44, weightmaintain : 1547.0375, weightgain : 1668.1100000000001 }, 
     fat : '36.0', protein : '103' }
