Can someone please explain what a fitbit does?

I have heard several times how getting a fitbit is good way to know how many calories to eat, but I just don't understand how it works! I have looked on the fitbit website, so I know it tracks your steps and how many calories you've burned. Does it measure your calories burned for the entire day, or just when exercising? And how does it know how many calories you've burned? And after it calculated how many calories you've burned, do you just calculate your deficit for there? I am so confused, please help!

    Activity trackers (including Fitbit) measure your TDEE (total daily energy expenditure). They're tiny computers with sensors called accelerometers that use algorithms to calculate how many calories you burn 24/7.

    Like anything else they're just estimates—but they're way more accurate than MFP or exercise equipment. You can connect your accounts (via the "Apps" tab at the top of every page). Then MFP uses your activity tracker data instead of your activity level to calculate your calorie goal.

    MFP has a Fitbit Users forum: http://www.myfitnesspal.com/forums/show/1307-fitbit-users
