Lucky you! I love Paris.
I've just had 4 days there and still managed to lose half a pound that week (even with all the vino I inhaled, I mean, drank!)
Breakfast, as Silvermaneuk said will most probably be a breeze - usually buffet style. Our hotel had muesli, lots of fruit, fat free natural yoghurt and loads of egg type stuff. I had muesli mixed into fat free yoghurt with fresh fruit. I had to tell myself to 'step away from the croissants' etc. Especially those choccy ones....
There is a big moroccan influence in Paris, which is good news on EE. I had couscous dishes or one night, a rather fabulous chicken tagine. Scrumptious. Have a look on Google at Chez Bebert - there are about 3 around Paris. We were staying in Montparnasse and there is one there. Get there early though as it gets very busy.
Another night I had grilled sea bass with the sauce on the side, served with julienne vegetables. It was delicious. (Check out Le Petit Sommelier - very French. Very good food).
During the day, most of the cafes serve SW friendly things like Omelettes. Just be careful about the cheese. Even if you ask for a plain one, there will be a HE or 3 hidden in it somewhere.
Wine is served in 120ml glasses. How rude. But very good for counting syns.
I could go on, but you're probably falling asleep by now?
Bon voyage!
