Ultimate weight loss calculator

Hey! I'm an amateur programmer and I made a huge calculator that figures out everything from your current BMR to your predicted weight loss over a period of time and a ton of other things. I hope that it will be a useful resource, and would love to get some feedback on it if you have a few minutes. You can check it out here: http://ift.tt/YiEcD1



P.S. Mods, I know self promotion isn't allowed but this isn't a product or anything, just something I made that I thought would be useful - I hope this is ok.
