Hi,
I haven't visited this site since months since I don't do any diet at the moment, in contrary I life a quite unhealthy lifestyle.

Anyway, as far as I know there is no page like fitday.com in German with local products. The ony help that I can give is that there is a software called Bodycap with 11.000 products which might be very useful for you. You can download a free trial version at their homepage.

Good luck in Bavaria where the people love potatoes and other high carb products and the people probably think that you are starving yourself to death.
