Kenya,
I started out using fitday and then got lazy. I also started letting more carbs into my diet because I didn't have to see that chart showing me how bad I was being. Now I'm back to using it! If I have too many carbs early on, I know I have to do pure protien for the rest of the day. If my fats are high I know I have to get leaner so I'll eat turkey or chicken instead of that hamburger I was thinking about.
I'm aiming for the 3 pie wedges like Bree said, but I'm allowing myself a few more carbs. I read somewhere that the percentage for a GB patient should be 40% protein, 26% fat, 34% carbs.
Here's another place online that I think will help you a lot, at least it did for me.
MyPyramid.gov - United States Department of Agriculture - Home It tells you how much of each food group you should be eating for your age, height and weight, and what are good choices of food for each group. RNY pateients don't fit the "normal" but it can still teach you about good foods vs: bad.
