calorie adjustment

[Love62]

What is the calorie adjustment for My fitness pal? I don't know where it comes up with burning so many calories when manually adding walking 30 minutes would only be 150 calories for me.

This is best explanation I have found for this. It is taken from the MFP forums and is written by Scott (a MFP staffer):

"To understand your Fitbit Calorie Adjustment for any completed day, take your "Calories burned from normal daily activity" on your goals page (http://www.myfitnesspal.com/account/my_goals) 

Add to it any exercise calories you've burned as shown in your exercise diary, but don't include your Fitbit Adjustment 

Compare that total to your calories burned on your Fitbit (only if it's an entire day's worth of calories) 

The difference between the two is your Fitbit adjustment 

The adjustment that you see during the course of an incomplete day is a projection made for the entire day, based on the amount of activity currently reported by Fitbit. Your adjustment will become more accurate of the course of the day, each time your Fitbit has a chance to update with your account on fitbit.com. 

Here is a more detailed explanation of the way we calculate the projected adjustment before a day is over: 

If you only have a partial day's worth of calories on your Fitbit, we calculate how many minutes are left in the day, and we use that to create a projection for how many calories you'll burn today. 

The calculation is: Fitbit calories so far for the day + (minutes left in the day / total minutes in a day) * (calories burned from normal daily activity) 

So for example, if it's 12 noon, you've burned 1200 calories so far today according to Fitbit, and your calories burned from normal daily activity on MFP is 2000, the projection is: 

1200 + (720 / 1440) * 2000 = 
1200 + (1/2) * 2000 = 
1200 + 1000= 
2200 
so the adjustment becomes 
2200 - 2000 (mfp calories burned from normal daily activity)= 
200"
