I just got my fitbit and am so excited to use it. I set it to 2nd tri in settings, but I'm just wondering if anybody can explain what this changes (I haven't been able to find anything else about it online). Should I set my Food Plan to 'maintain' and it automatically adjusts what my calorie intake should be? That's my biggest question! I want to know how many calories I should be eating, and keep track, but just want to make sure I'm tracking to the right number. Thanks!
