Help!! Unable to achieve fitbit calorie goal

You burn a lot of calories in your sleep, sitting down, etc. Your heart is a muscle and needs calories to beat. Your diaphragm is a muscle, it needs calories to make you breathe. Digesting food burns calories. Etc. Your goal includes exercise calories and not-exercise calories, it's for your total burn.

If you're burning 2,120 and eating 1,200 that's a very large deficit!

Are you sure you are not confusing your calorie goal with your daily calorie burn? The calories that show on Fitbit are what your body currently burns. That's not the number you need to eat unless you want to maintain your weight. To lose weight, you may want to eat anywhere between 1600 and 1850 depending on how much you want to lose.

Also, if you aren't logging your food, there is a possibility that you're under-estimating your calories. Humans are bad at estimating calories, especially those who have weight to lose. If you want a more predictable process, start logging accurately. It helps you make sure you are not undereating/overeating.

Thank you for all the helpful answers:

I am a female, 5ft 2inches and at 57 kg.
On mfp i selected sedentary lifestyle as wasnt working out and chose to lose a pound per week.
Yes i mean my daily calorie burn goal is 2120 calories which i never achieve. I always hit 1800 maximum. Thats what I dont understand how to achieve a 2120 calorie goal.

more exercise. but honestly that goal of burn rate is very random. i found that as well with fitbit. the only time i hit it was if i did long distance running that day. Even a 5-6k run and 18,000 steps i wouldn't hit the 2120 calorie goal. i'ts a fake goal you should ignore. or change manually.

i'm not even sure why they set it to that.

So your Fitbit adjustment is taking you from sedentary (which you now are not) to active (which is what 10,000 steps is).

2100 does seem pretty high for weight loss though, and I doubt 1800 is way too low. Some people do find activity trackers give them a few too many cals. So I'd just stick with 1800 for a few weeks and if you are losing weight at an appropriate rate, stay there. If you are losing faster, you can eat more by eating more calorie dense foods, but I wouldn't worry about that until you know it's necessary. (You are already in the healthy weight range for your height, so you really shouldn't be losing faster than 1lb per week)

I only get the 2100 if I walk 20,000+ steps like I said (or run long distance much more than 5km). They say they base i ton this:

I basically learned to ignore that number :P it's also not the amount for weight loss it's just a goal of calories to burn daily. The number also did not change after losing 50lb

If I understand you correctly the above image shows my Fitbit activity for today. I personally treat the circles as separate goals. I start with the right circle which turns green once I reach 30 active minutes (continuous minutes of activity). Then I move to the left circle which turns green for me at 5 miles. The center circle of activity burn I only occasionally make a goal for myself to achieve this goal. It turns green for me at 2185 calories. Typically when I reach that goal, I have walked 17,000 to 19,000 steps (around 8 miles generally) or had an otherwise really active day gardening of running.

Those are adjustible .. goal wise.. cal burn.. not necessarily the cal you need to eat.. it's a counter how much cal you burn so far in real time..(it resets at midnight)

Look at the food section of Fitbit.. it should fairly set to same number as mfp. (That is if you put in your data /information... Height , weight, age etc.)

That's the number you need to pay attention to.

Oh I misunderstood you. You basically want to do enough activity to reach a high calorie burn goal. With your current stats, it may not be sustainably achievable unless you want to walk even more steps than you currently do. Don't worry about the calorie burn goal, or just go to settings and put a more reasonable goal for yourself.

FWIW I prefer to track my calories eaten on MFP and let Fitbit pull the data over. It’s interesting to look at some of the charts. I use the Fitbit goals as incentives to move more

If you were in a coma, lying in bed, your body would need, say, 2000 calories just to sustain itself. Or, in your case, 2120.

OP is a 5'2 female, 125 lbs. Her BMR would be more like 1400 cals.

here are two examples. i am 5’1, female, 115lbs. My steps are just short walks (under an hour) and moving around (I pace while waiting for bus). no purposeful exercise. One day I went over 20,000 steps and got the calories burned to "acheive goal".

@sumayaiphone -
I think I saw one reference to what you are talking about - the Fitbit daily burn goal - they default set it based on calculation - you can manually set it too.

It has no bearing on any math, just like MFP has eating goals - Fitbit has activity goals.

Some people know they do well if they can eat say 2000 calories daily - that allows them to eat a variety of things, get their nutrition in, and still enjoy something higher calorie.

But they want to lose 1 lb weekly - so they set their Daily Burn goal to 2500 - giving a 500 cal deficit.

They know if they don't appear to be on track to hit it - they don't get to eat as much.
MFP obviously helping with that side of things.

MFP's estimate of daily burn early in the day, will likely not project out to that - unless your daily activity really will match the activity level you set MFP to.

@BattyKnitter - it's not actually steps - it's the distance from those steps that gives the calorie burn. So easily can have variance between people, and even between your own days.

@verybusymomto4 - that's not exercise burn - but daily burn. avg sedentary female is actually figured to be about 2000. variances in height and activity obviously mean differences.

Hmm this makes me wonder if my Fitbit isn't way overestimating my calorie burn. I routinely burn 2000 cals with 10 000 steps, 20k steps like poster above has me at 2500 cals burned. I'm short (5'2") but I am heavier at 142 lbs.

2000 a day on 10k steps? wow. i only burned 700ish on 11k steps this morning.

Yeah not sure but I am losing weight as predicted by my deficit so I guess I'm lucky? It may lower by quite a bit when I reach my goal weight.

This was Monday which included a slow 5km jog:

Well I have no idea how anyone can burn 2,000 calories! I can’t even burn 1,000 and I’m always going!

The burn shown on a FitBit is total energy expenditure, not just energy expenditure from steps or exercise. You burn a *kitten* ton of calories merely existing.

It’s hard to imagine that some of us burn so few calories. I’m 5’1”, female, 140 lbs, over 50, and I have a sedentary job. It takes a lot of effort to burn 2000 calories (including bmr) for someone with my stats. But my stats also put me in the overweight BMI. I have 10 lbs left to be a healthy BMI and I’m losing at a rate of 0.2 lbs every 7-10 days. I always assumed the calorie burn goal on Fitbit is higher for taller/heavier stats.

The burn your FitBit is giving you isn't just for the steps...it's your total energy expenditure, including your BMR, etc.

I burn around 2800-3000 calories per day...very little of that is my actual exercise...most of that is my BMR and my normal day to day type of activity.

Yes I knew this so I guess my NEAT/BMR/heart rate may just generally be higher than others who have posted in this thread.

No - Those other posters are misreading what's being said and either don't realize they do burn around that probably in total - or think you are talking about MFP adjustment perhaps.

Looking at the pictures in this thread is pretty easy to tell what is being talked about - the problem is do people realize what that means.
