just bought a Fitbit flex , my only question is understanding the positive/negative adjustments . Can someone explain the two to me please ? Right now it's says -100. Is that good bad ??

Your calories are adjusted based on your activity level here vs. what Fitbit reports as your activity for the day. If Fitbit shows you are less active, your calories go down. More active and calories go up.

Does that help?

You've burned 100 less calories than fitbit expected/predicted of you..
I wake up to -100 most mornings. It slowly moves up to + adjustments once i start walking.

So -100 cals means I'm inactive ? And when I'm active my calories will be positive ? Sorry if u just said that I just wanna make sure I understand

It means you've burned 100 fewer calories than your activity level.

There are in-depth explanations in the Fitbit Users group:

The -100 means you're less active as of that moment than what MFP thinks you should be.

Like Christine said - you will probably see the negative number early on. As you get more steps in, you should see a positive adjustment. I start seeing positive adjustments once I have ~2000 steps.

Here's the explanation I posted in the Fitbit Users group: http://community.myfitnesspal.com/en/group/1290-fitbit-users

You lose weight by eating at a deficit—which means eating fewer calories than you burn. For every .5 lb. you want to lose per week, your deficit is 250 calories per day.

Your default MFP calorie goal is activity level minus deficit. Your Fitbit burn is TDEE (total daily energy expenditure, aka your maintenance calories). Adjustments are the difference between your Fitbit burn and your activity level.

Click on any adjustment to see the math MFP used to calculate it. For example:
Fitbit calories 1,238
MFP calories 1,413
Adjustment -175*

*If you disable negative calorie adjustments, your adjustment is zero—and you don't eat at a true deficit.

Negative calorie adjustments never, ever put your calorie goal below 1,200. So if you set your goal too aggressively for your size, you still won't eat at a true deficit.
