Yes, Fitday is great. I just started using it a couple of days ago and I really like it. Before I didn't even know that there are carbs in coffee and diet soda.
I'd say keep coming back here often. I learn something new everyday. Check out the recipes so that you don't become bored. This is a really good website. Learn to navigate around here. There's a section here with tips. Also read postings by other people. Some people will have a link to their fitday and you can see what they're eating. Some people will put in their journals what they're doing.
And don't forget to look at the before and after pictures for inspiration. It would also help if you keep a journal here.
Good luck and don't hesitate to ask more questions.
