a pregnancy blog
I hope it helps! Like I mentioned on Twitter http://www.loseit.com/ is a good tracker, they also have an iPhone app. It breaks how many carbs/protein/fat into percentages, shows a pie chart for what percentage of your calories you take in at breakfast, lunch, and snacks. My dietician recommends that breakfast, lunch, dinner, and snacks should be balanced, meaning each about 25% of my daily intake. She also recommends using http://www.sparkpeople.com/ to see vitamin and mineral data (Lose It doesn't track them as well) but cautions that they send a lot of e-mails so use a junk e-mail address if you sign up.
