If yesterday was a typical day for you then you can expect to get a similar reading every day, in which case if your Scooby calculations settings you're currently using on MFP are hugely different you can just change your goals manually up or down accordingly.

If your activity levels vary from day to day, get a couple more readings and calculate an average to set as your goal. As you get more data you'll get a clearer idea of your TDEE.

I agree watch it for at least a week to see an average maybe even longer. My TDEE can vary on the fitbit as much as 800 calories during the week. Depending on how active I am. Scooby set my TDEE as 2725. My fitbit TDEE this week had a high of 3100 and a low 2300. So 2700 is a good average and I am sticking with that. Also the fitbit only counts the walking type activity. If you lift or swim it will not count that. Something to keep in mind.

I love my fitbit. I was so disapointed when I forgot it on the charger when I took my kids to a science museum. I walked the whole day we opened and closed the place. I sat down for about 20min for lunch. I would have loved to see how much I walked. I get so used to havig it on. I even use it to walk my stairs when I can't get to the gyn for some reason. I love to best my last number. Not loving the negative exercise score but it will grow on me.

thanks guys

silly question how do I see what my TDEE is given from fitbit? Is there a view on FB to show it? or do is it the 'calories burned' figure?

cheers

If you go onto your fitbit dashboard online you can change the date to look at previous days. The 'calories burned' number from previous days will be your TDEE of that day. It includes your BMR, projected calories burned by activities of daily living, calories from walking etc as calculated by fitbit and any other calories that you may have logged separately for exercise activities.

Good information here about the fitbit. Bumping so I can check my numbers.
