Shoot for 10-12 times your goal weight in calories. I agree, I think you're not eating enough. You should add some more vegetables (3 cups a day).

Fitday is great, but it does take some dedication. It can be a real eye opener, though. Every now and then I'll still be amazed at the amount of calories or carbs I'm eating when I thought I was being good. Things can sneak up on you...

Also, beware the advantage bar - they affect people differently, but some find they contribute to stalls.

You don't seem to be having that sort of problem, though!
