Lol I was just reading that. Aside from the Dukan mayonnaise which doesn't sound that appetizing, what do you have tuna with? Also, what do your typical breakfast, lunch, and suppers look like? I know there's the concept of unlimited but I feel like if I'm not structured I'll just overload.
According to their calculations, I only need to "attack" for 2 days and "cruise" for 32. Should hopefully be manageable..
First of all I use light mayo. As a rule of thumb if it's less than 5 grams of fat then it's low fat enough for Dukan.
As far as my meals, it varies. In general for breakfast it's the oat bran pancake (you can shmear some low fat cream cheese on it) and a plain Greek yogurt with splenda. Lunch can be eggs, tuna, sardines in tomato sauce (which are allowed even in attack phase), farmer or cottage cheese, light Greek strawberry yogurt or a diet cheese cake. Snacks are mostly diet American cheese and cheese strings and on vegetable days your options are much more.
For dinner it's either fish, chicken, meat etc. On vegetable days you can make a veg soup and my favorite... spaghetti squash. Mashed cauliflower makes a good mock mashed potatoes (throw in some American cheese if you want!) and you can make carb free gefilte fish balls in tomato sauce which are probably allowed even in attack phase) And don't forget about cheese latkes and blintzes using corn starch but I would stay away of corn starch in attack phase.
Have fun and good luck!
