I don't know if it's 100% accurate, but fitdayonline.com has some criteria you enter (age, height, weight, activity level) plus you can add daily activities (and it's pretty specific--even includes bedroom romps!) to figure out your calories burned per day. You can enter your foods as well and it will break things into percentages, show you nutrition goals, calories, % protein, fat, carbs, etc.--even the poly, saturated and monounsat fats. I use it and it works fairly well. It's nice to see when you are doing well, and you can track your progress over time. It's free, otherwise, I wouldn't use it. :wink: I can't vouch for the accuracy of it, but it seems pretty decent.
For me, it works as more of a boost than a detriment. Although I feel like I am eating a ton, I can see that my % are in the Zone (proof beyond how I feel) and that my calories are still quite low. It's exciting to see hard evidence that you are burning calories even when you don't feel deprived!
It was my anniversary last night, and I admit we overindulged a bit at dinner, but even so--I could see that I didn't stray too terribly far and still burned more calories than I consumed yesterday. Very uplifting!
Just a tool that may help you--it does for me.
