Calorie Calculator Tool

Hello, Need a Calorie Calculator: I need a very simple tool to give away from a website. The tool should be html script which can be copied from iframe. The calculator is to be similar to [login to view URL] - only metric parameters are needed. Only parameters it should contain are- weight, age, gender, height, exercise level The website language is Hebrew, therefore Hebrew translations for the titles has to be possible (or I should be able to change the titles inside the html code to Hebrew) The tool should include anchored link to my website The tool should be simply but nicely designed I do not know if it is relevant but please note that I can not upload any files or data on the website server. Thank you
