Thanks for the replies.. I was unsure of calories as I have never counted them before... so i think that right now I feel pretty good and in control with about 1700-1800 calories. I feel satisfied, not full though but not hungry.
I also have no idea about the ratio of carbs, protein and fats... any hints on those... the days when I feel good - seem to be a 40% carb, 30% protein and 30% fat intake day.... does that seem right?????
One of the things that I also like is being able to check my intake of iron etc.. I have noticed that I am very low in iron on most days - probably why I am so tired!
I use a mac so the fitday software isn't designed for it - I wish they would do a version for apple.
Thanks again for all of the help
