food journal web application

I have an existing website that is subscription based. ? We have a database ([login to view URL]). ? We want to add a food journal/diary to offer? existing? and some new members. ? The application I would like to tailor it after is [login to view URL] . Application MUST: **work with our? existing? database (will need plug-in) **track calories, fat, fiber, protein, etc. **have an extensive database of foods that can be added to their personal log VERY EASILY **have an extensive database of prepared foods? commonly? found in grocery stores or in? common? restaurants. **have a "favorite foods" section that members can easily access to add food to their diary. ** have a place to manually enter new foods not in database. **have a place to record weight and measurements **have a graph that shows their weight changes **exercise tracker: ? be able to calculate calories burned in common exercises? **must integrate with the look of my site other features I like that are not required: **calculate amount of calories each day one can eat and 1)maintain weight 2)loose 1 pound 3)loose 2 pounds **graphs showing weight changes Any other ideas are welcome! ? ? ## Deliverables Navigation throughout the application should be VERY user friendly.? ? It must look like the rest of my site.
