Is net calories meaningless?

Net calories is calories consumed minus calories expended (either via exercise or an activity tracker). Your calorie deficit has already been accounted for, so your net calories should ideally be the goal you are given, as MFP is set up for you to eat your exercise calories back.

See, this is part of what I don't get. Common forum-advice is not to eat back all your exercise cals because of machines and trackers overestimating. But even ignoring that, I'm short, so my sedentary maintenance is somewhere around 1400-1500. I'll typically eat ~1400, get 10-15k steps which my tracker gives me at around 450 calories. So, my "net" is around 1000, but my defecit is still around 500ish. If I ate up to 1200 I'd be eating away my deficit and not losing weight. right?

Are you talking about your real life results or your expected results?

You are EXPECTED to eat back ALL your exercise calories and NET your GOAL to lose at your selected rate. Your goal amount ALREADY INCLUDES your selected deficit.

If your goal was 1200 and you ate up to 1200 you would be eating at your 500 deficit. By eating 1000 you are creating a 500+200=700 paper deficit.**

Then real life and the potential need for adjustments intrudes.

**1200 is a special case on MFP because it is also the floor below which MFP does not go. So there are many situations where a goal of 1200 does not actually provide you with the deficit you think you've selected.

Personally i just use my fitbit to log workouts.. i don't trust the step counting with MFP even if its getting the information from fitbit..

So you selecting from 4 rough levels of only daily activity on MFP, and logging, or rather it sounds like not logging your workouts - is more accurate?

Of all the numbers - 0 calories for exercise is the most obvious incorrect one.

The whole NET calories idea is thrown out the window when you have MFP correcting itself to better estimate from Fitbit for increased daily activity and exercise calories - because there is no split as to what is what.

NET in the non-sync tracker realm is dealing with taking exercise calories back out of the math.

But since on Fitbit you could have no exercise but be very active over Sedentary, you could have big adjustment.
Or you could have big workout and then really tired and have no adjustment.

So the NET thing doesn't make as much sense then.

Just eat what it tells you to eat.

The adjustment is just MFP trying to correct itself because they realize a better estimate is available.

You can confirm the Fitbit side is giving best estimate too though. Both for daily life and exercise.

This makes it sound like workouts are only logged on Fitbit, which is fine, and actually more accurate for calories from the database.
If you mean Fitbit track your workouts, good again.

But I'm assuming if you don't trust the step counting with MFP from Fitbit, you actually mean calories, because really, who cares if steps was showing as wrong on MFP where they really don't matter for contests and challenges and such.

Sounds like you are saying you don't trust the calorie adjustment, and like so many others - ignore it.

To which my point is - 0 (or ignoring) is the one wrong answer no matter what.

If you meant something else entirely, then I really don't understand unless you literally mean MFP's app's ability to do step counts if you so decide to deselect Fitbit and select MFP.

See - that's what is confusing.

Where exactly are you seeing a "steps adjustment"?

And what type of workouts are you tracking with what Fitbit model?
I'm assuming that means you are letting the Fitbit decide the calorie burn then - in which case method and type matter big time.

So HR-based calorie burn device for exercise.

A few potential issues that cause inflated calorie burn.

It doesn't have a good line for when it should be still using step-based calorie burn, and it's using HR-based during daily activities - that's inflated.
You can usually see that in the daily 5 min graph where calorie burn just shoots up and it wasn't workout time.

Your stride length setting is off badly and you get lots of steps in daily.
So it's inflated distance and calorie burn.

Or, you are set to Sedentary as many are with trackers - but your daily activity is no where near sedentary, you get upwards of 10K steps even on non-exercise days - in which case that could be reasonable, or at least understandable especially if stride-length is wrong too.

Some set stride-length to exercise level pace, even though that's not the pace for 90% of their steps daily - bad inflated distance/calories.


Curious - what does this mean - "the burn i get from fitbit once i start the timer for the workout is what i use"

I know Fitbit logs an Activity Record for exercise - I'm just curious what you use it for?

Are you logging that back on MFP as a workout so it shows up on your wall?
Using the correct start time/duration? Got your time zones correct between accounts?

You aren't manually logging that on Fitbit, right? True, it would just overwrite the exact same info, if start time/duration matched.
