Hi Suni!
I haven't read TSP II yet, so my info is from the 1st TSP book and personal experience.
Although Dr Schwarzbein does not advise eating man-made carbs such as bread, she does say for convenience sake, some are better than others ie whole grain. I imagine pasta would be in the same category.
I don't count carbs, I just try to keep my serving sizes of them within the range suggested in the book. I am allergic to all grains except rice. I have brown rice pasta maybe two or three times a month. I keep my serving size about 1/3 cup. It is always with protein and lots of salad and/or veggies. And when I get full, it is the last bites of pasta that get left on the plate, not the protein or veggies.
I would say your whole grain pasta with pesto lunch should be ok once in awhile but you should include some protein such as chicken or turkey breast, I don't think the parmesan would be enough protein to balance the carbs. Also make sure to eat some veggies or salad with it. Same thing goes if you were to eat the pasta as a side dish for supper.
Just be sure to keep your portion size really modest. Since you are so close to goal, ie normal body composition not overweight, you are allowed 30 - 45 g of carbs per meal if you are Somewhat Active, up to 60 if you are Active and up to 75 if you are Extremely Active. (see pg 260 in TSP). So just calculate the carb count for the pasta and you should be ok. But don't forget the protein and veggies!
HTH,
