hello all, new here

some friends told me about zoho and thought you might be able to help me.  I have my own website I am building, already paid for so I can't switch over, but I am hoping you still might be able to help me.  I want to embed a program(don't have it, can't find one)that will allow my members to keep track of their food intake as well as their fitness tracking.  Does anyone have any suggestions for me?  I know how to use Excel, Access and the lesser forms of those programs in MS Works.  But I don't even know exactly what I need to do.  I can't imagine starting from scratch to enter in 5000 foods and their nutritional facts, as well as different fitness activities with calories burned.  Then I also need folks to be able to run reports to see where they are in reaching their goals.  I see these "programs" all over the web but darned if I can figure out how the sites built them:(
 
Thank you in advance, denise
