Fitday uses a formula based on the information you give it. How active you are, how tall you are, what type of job you have. It gives you a number for Basal Metabolism and a number for Lifestyle. If you enter information in about activities it gives you that number as well.
I find it pretty accurate, however it can be off by 10-15%, it's just a formula, after all. I know when I first started off at +250 lbs it was on the high side and now it's on the low side, but it's still a good reference.
Keep in mind that the RMR part of fitday is the Basal number - not the total. The total of all the numbers in fitday is what they estimate you burn in a full day, not what your body needs to survive.
Wenzday, I agree, you don't need to eat that much, and good luck trying to! But if you have the odd higher calorie day, don't sweat it - it may actually be a good thing. Keep the body guessing.
In theory to lose fat you need to eat a few hundred calories below what you expend, in total, on any given day. The more you expend vs. the number you eat the more you
should lose... but it doesn't always work this well. A deficit that is too great will put stress on your body and fat burning comes to a halt. This is why we often don't lose weight when we eat less calories, too much of a deficit, too much stress.
You have to figure out what works best for you. Trial and error and some calorie fiddling - but only if it's broke. If you're eating a reasonable amount of calories and you're losing, don't mess with it!
