    I have been logging on mfp for for something like 465 days. I went from almost 300lbs to a low of 165. I understand how to log and what to log, Im just frustrated by how far off the exercise calories or rather the tdee that fitbit gives me seem to be. I'm on my phone but will check out your spread sheet in the morning.

    As mentioned before there is estimation and there is reality.

    And the confounding effects of water weight and body composition changes which make each lb change NOT equal to 3500 Cal.

    Furthermore, depending on the size of your deficit and the amount and type of exercise you chose to do, there is a component of thermogenic adaptation that takes place during weight loss (a TDEE reduction that is not explain by a changes in metabolicaly active mass). These adaptations may take a long while to reverse (if they every do). Exercise adaptations sometimes reverse after a few weeks of not doing the activity you've adapted to)
