. I'm set to lightly active right now and have a 422 calorie adjustment from Fitbit already.
Yeah, I think that's what's going on. She has been using "activity" and "exercise" interchangeably.
However, I have to do something like 30k steps to get anything close to a 1,000 adjustment. I don't have my MFP settings on sedentary, though, I think it's active or lightly active and begin the day with 1463 calories that I set myself with negative adjustment turned off. I weigh 186.
I'm at 45,600 steps with my short, squatty legs to get 1,000 cal just from activity. lol. And I AM on sedentary!

I have to walk around 21,000 steps or over 10 miles to get to that magical 1000 calorie burn. I've been trusting my fitbit, and so far so good.0

I think that's what's going on. Normal daily activity burns and exercise burns are not the same thing. For Pete's sake
Oh and I saw my post earlier today now has a flag...LOLOL
I've STRUGGLED to get anywhere close to 2,200-2,300 cal a day total burn. STRUGGLED. I'm trying to keep on a 1,000 cal deficit challenge. It's very, very hard for me. I'm walking on a treadmill as I type this!0 -

Burning 500 calories is light years away from a strenuous workout.
If a Zip is going through more than about 2 batteries a year, it is defective. This happened to me--I called FitBit and received a brand new Zip in less than a week.
You can't make blanket statements about other people and exercise, and you always, always do. It comes across as annoying and judgmental. Everyone on here is at a different part of their fitness journey. People are also differently abled, and differently sized.
Additionally, the amount of calories you burn depends on how much you weigh, how fit you are already, how long you exercise and a host of other factors.
I am middle aged.
I have a desk job.
I have fibromyalgia.
I have several very significant injuries that limit what I can do in terms of exercise.
Still, I don't think that I have EVER had a day when I burned less than 1000 calories in activity. I am usually in the 1500-2000 range, even when I'm not trying terribly hard. Yes, I am a tall/large framed person and obviously that makes a difference in calorie burn.
A lot of people here have been very sedentary for years and they have really skewed ideas about exercise. Many of us are from cultures where being inactive is considered acceptable, especially as we age. There are a lot of people on MFP who are not very interested in being physically active. While it might not be necessary for most people to work out a lot in order to lose weight, being active IS important for quality of life and overall health.
Brag about doing 500 calories worth of exercise and you should expect to be corrected. That is just NOT much.
This has to be bmr, or your tdee....
In order to truly "exercise"and burn 500-1000 cal. would take hard work.
and it IS ALOT of work, hard work and time !!
you are middle aged, desk job, with pain... to exercise (walk,run,etc) and burn 500 is hard to do.
You have to be counting just living calorie burn. (tdee)

It's weird what goes on in some of these threads.
Arguments between apples and oranges over what is a lot of exercise or a little.
Competing over who had the most illness/disabilities.
To all the people who have a fit bit do you have negative adjustments turned on? If you do it should matter which setting you have it on in mfp, sedentary or active.
Some days I am super sedentary and need to exercise to get up to what mfp considers sedentary

That don't make no sense.
How are you set to sedentary and doing 45k steps and only getting that small of an adjustment. Are you super fit and walking is really easy for you?0 -

I'm having the reverse problem, I think. I'm wondering whether the Fitbit is underestimating what I'm burning. Today I took a 30 minute walk (1 mile and a half), did an hour yoga class (average to gentle, not power), laundry, some light yard work -- raking and seeding for about half an hour, and another 20 minute walk (about a mile) before supper. Before lunch but after my 30 minute walk, I got around 60 exercise calories from my MFP adjustment, but by the end of the day, it was down to 13 -- calories got taken away, even though I wasn't exactly a couch potato. Right now, my total calories used from my fitbit, which I assume is my TDEE is only 1245 calories. I know I'm small (5'1.5") and over 50 years old, but still this doesn't seem like much for that amount of activity.0

I think it's still small but I just realised I was mixing up calories and kilojoules

Do you have mfp set to lightly active? How many steps have you taken? It won't really credit the yoga or seeding, just steps.0 -

Today, I did over 11,000 steps. I'm also using the Fitbit HR, so it's measuring heartrate, not just steps, so I'm assuming it's calculating my TDEE since it's measuring how many calories I burn all day based on that. I would assume yoga wouldn't burn too many calories, but yard work and such would. MFP has me set to eat 1200 to lose; I've actually reset to 1000 calories because I do have a low metabolism (it was tested and showed 1136 BMR). However, I assumed BMR is when you're doing practically nothing. 1245 is not much higher than that and that's what the fibit shows I've burned in a day's activity.0 -
All this is why I keep MFP and my fitbit separate for right now. I'm pretty sedentary and my step count is low (only 1 - 10k days a week). I am comfortable with using it's exercise workout calorie burned approx and just manually enter on MFP. I've had it about three weeks. I might change in the future but for right now, it's simple and straightforward...which I like.0

Yes, I have negative adjustments turned on. If you do, it doesn't really matter what setting you have on MFP. You won't get any exercise adjustments with the FitBit until you are already over what it has calculated for your TDEE on MFP. If you have it set for sedentary, you'll get to that amount a lot quicker than if you have it set for active.
I have mine set for active I think...and it takes about 5000 steps before I get any kind of adjustment. Today I walked 18K+ and got about 700 calories in an exercise adjustment.
What do you mean? If you have negative adjustments turned on you get an adjustment as soon as you synch with fit bit for the day.
Say I wake up and synch Fitbit, I might have 15 steps and it will give me a negative adjustment of like 700 kj.
If your not getting adjustments until your Fitbit tdee is higher than mfp doesn't that sound like you don't have negative adjustments on?0 -

Hmm, I don't have the heartrate monitor, idk. Hopefully you have some time until midnight (it's 6 out here), that does sound low.

If I have mfp @ sedentary it creates a smaller deficit than what I want because a 1000 cal deficit at sedentary would put me below 1200.
And since mfp doesn't allow a deficit that would put a person below 1200, all fitbit adjustments would be to maintain whatever the deficit would be for me at a 1200 calorie goal. Mfp therefore will operate as if I chose 672 (?? or whatever) for a deficit even though I did not, I chose 1000 cal deficit. But sedentary setting makes it as if the deficit created at the 1200 cutoff is what I wanted. So I have to pick an activity setting that allows a full 1000 calories to be taken from mfp's estimated tdee for me at that setting without it dropping below 1200.
I have negative adjustments disabled because I'm consistent in activity, I don't have sedentary days, at most I have sedentary mornings and afternoons...; the negative adjustments and being in the red for calories at any point in the day is just annoying to me at this point, it makes me like like I'm being scolded despite not having done anything wrong yet... Last summer when I got my fitbit my lifestyle was very different than now, when being consistent wasn't yet a habit and I didn't trust that I'd do what I needed to do to maintain my deficit, and fitbit and mfp wagging their finger in my face to get moving was motivating, but now not so much. I do however think negative adjustments being turned on is ideal if you have sedentary days and/or are inconsistent in your activity.

I see the negative number as motivating. Say I sat around most of the day relaxing. I see I need to spend 15 mins on a treadmill so I jump in be fore dinner or while I'm cooking.

I find it motivating too. It makes me work harder so I can get back into the green as quickly as possible.

Is it really true that if I go to bed with 600 calories uneaten, and I'm not feeling deprived, I'm full and satisfied, that I won't go into "starvation mode?"
If you went to bed with a 1,000 calorie deficit every day for 6 months, and you were less than 1% body fat, then you might go into "starvation mode". If nobody mistakes you for a POW from the Hanoi Hilton, you are NOT in starvation mode.

I get that. As i said in my post, that was motivating for me too. It's just not anymore, at least it hasn't been at this point as my activity has become such a habit that I would do it regardless of whether mfp and fitbit scold me or not.Lourdesong wrote: »To all the people who have a fit bit do you have negative adjustments turned on?

And since this is so, my settings are such that I prefer not to be scolded If I don't have to be. But I wouldn't hesitate to go back to being pushed if I need it. And I do still move more if I wish to eat a little more.
But all this is only relevant for my purposes of explaining to you the combination of factors that made it sensible for me to select a higher activity setting and have negative adjustments disabled. I get the impression that many assume sedentary is the safer choice to ensure they don't overeat, but in reality I would recieve significantly more calories from adjustments for sedentary setting not only because I would begin the day with a lower calorie goal than I would at a higher setting, but also because mfp would believe I wanted a smaller deficit than I actually do, as well.0
