I have a fatass facebook friend (that I keep for the lolls) who is always posting about fitness, and one thing i see often is her posting her fitbit info. It'll tell her that walking 20,000 steps burns 3500 calories. I mean yeah, your'e a whale, so you might burn more calories than a thin person walking, but there is no way in hell it's THAT much. I mean, 20,000 is what the average person is walking in a day. And that accounts for your TDEE already, not on top of you TDEE like she thinks it does.  Also noticed she stopped working for Herbalife too.
