Maths was never my strong point

Go by one or the other because each estimates the cals differently. Also keep in mind that the way MFP us set up you should eat back about half your exercise cals.

I'm using Wed figures.

Let me see if I've got this right. I can understand that both apps count the figures differently; a bit like Celsius and Fahrenheit? Up to now I've been running with MFP, my intention would be to stick with them. So MFP is showing my exercise as 1015. Divide that by 2 and you'll get 507.5. I'm using exact figures just to understand, I appreciate you'd round up/down

So I add back 507.5 calories to the food I've eaten (2363 cals ) that would leave the count in MFP 2363+507.5 = 2870.5, within 1.5 of Fitbit's calorie burn (2872). Am I figuring that correctly ?

For clarification is MFP saying I should eat back about 507 calories? Do I then ignore the figure 152 Remaining that it shown at the top of the food dairy, or is that in reality what I can eat back? Is the 507 just, so to speak, just like conversing C to F only this time it's MFP to Fitbit? Very confusing.

Now I'm confused.

Fitbit shows your exercise/active calories as 1207 for a total of 2780
MFP shows them as 757 for a total of 2257

Where are you coming up with 1015 and 507.5.

As others have said, you'll never get the bunbers in the two systems to match exactly, they use different algorithms: I've used FitBit and MFP for about 4 years now, successfully losing weight and now maintaining trusting the two systems to work together.

It helps if you understand what they are measuring and how they adjust your cals accordingly.
First, MFP. It's a NEAT calculator, meaning when you put in your stats, a goal weight, an activity level and a target rate of loss, it calculates a calorie goal for you that doesn't include exercise. You said you were aiming for 1.5 lb/week and MFP gave you a goal of 1500. That means MFP thinks your maintenance cals are 2250, that's what MFP estimates you normally burn without exercising.
Now FitBit. It's an activity tracker meaning it measures all your step based activity and heart rate (some models) and based on the stats you entered, it calculates a total calorie burn for you. You said yesterday that was 2780 at the time of writing but you can go back and look at the final number.
They work together in that FitBit sends info over telling MFP how much you've burned, and MFP gives you an adjustment based on the difference or what it thinks you will burn in a day (2250) and what FitBit says you've burned so far, and it even predicts what it thinks your full day burn would be (so you might see adjuetments go up and down through the day). Enabling negative adjustments means until you reach that 2250 mark of predicted total calories burned, you'll see a negative cal adjustment, but It will increase as the day goes on.

So the 757 adjustment you saw yesterday was FitBit telling MFP at that time that it thought you'd burn roughly 3000 cals by the time the day was Over.

How much should you eat? I always eat back all my cals as I've found regret two systems to. E accurate and reliable. You might start with half, so about 350, and adjust over time based on your actual results.

Last point, is 1.5 lb/week the right goal for you? Do you have 50-75 lbs to lose?

Help me understand this. I have Fitbit and MyFitnessPal tied together. After putting in all the relevant information MFP set me a target of 1500 calories per day to loose 1.5 lbs per week. I have set my own goal in Fitbit to the 1500 calories.

At the time of writing 22.40 Fitbit is showing me 1573 calories in, as is MFP, that's 73 over my daily total. That's fine. However Fitbit is also showing that I burned 2780 calories. So am I not 1207 calories to the good? ( 2780-1573)

Hop over to MFP and I'm presented with the figures Goal 1500; Food 1573; Exercise 757; Remaining 684. MFP also shows a calorie adjustment of 757

I don't understand the relationship between the 1207 calories in Fitbit and the 684 that MFP shows as remaining!

My main exercise today came from 15000 steps. Can you help me understand those figures?
