Is eating 4% below BMR really that bad?

So I constantly hear that it is bad to eat below BMR - but some say it is ok.
My activity level right now is sedentary. I have 41 lbs to lose til goal.
My BMR is 1547.
My TDEE is 1856.
TDEE - 20 % = 1484 - this is 63 calories below BMR and about 4%.
I'd like to just set my daily calorie goal at 1484, is this still considered an awful thing to do, and if so, why?
Yes, I could eat at a lower deficit - but with it being so close - I'm curious if it even matters right now.

I'm curious about this too because I discovered today that I was doing the same thing unintentionally.0

I didn't know anything about TDEE and BMR when I first started - and lost 40 lbs. Now I want to do it correctly.I'm curious about this too because I discovered today that I was doing the same thing unintentionally.0 -
I say just set it to 1500 and be done with it. I like nice even numbers!0

No. 1484 is a perfectly appropriate calorie goal for you.
However, you should not find yourself actually eating that many calories often. 1856 is your *sedentary* TDEE, so you need to add exercise calories on top of that. If you spend half an hour on the treadmill, your TDEE for that day will be morelike 2156. This means you'll have to eat about 1784 calories that day.
IMO you should set your calorie goal in MFP to 1484 and add exercise calories. If you find yourself eating fewer than 1547 calories often, it means you need to start getting a little more exercise. The fact that 1484 is below 1547 is completely irrelevant.0 -

I'm with you on that. My BMR is around 1777 (according to MFP) and the goal it set was 1720. I bumped it to 1900 just to be safe.
@Bonny619, 1500 would still be below her BMR. I think the concern is if being just a little below BMR consistently is ok.0 -
I understand that it's still below her BMR and I feel it's ok.
But I wouldn't go below that. And like Jon said, add some more cals on higher exercise days. 0 -

My activity level is sedentary right now, as I stated above. I am not exercising at this time - so I would be eating 1484 every single day. (or average for the week).
So is that a problem then?
Also, in your example, if I ate 1784 and then burned 300 calories exercising, I'd still only be netting 1484 anyway. So how is that any different?0 -

I don't recommend trying to lose weight while living a completely sedentary lifestyle. If you simply can't exercise for some reason, IMO it's better to try to maintain your weight, or lose very slowly (TDEE-10% or so).0 -
And what exactly is the reason for that? You don't have to exercise to aid in weight loss, it just prevents muscle loss.No. 1484 is a perfectly appropriate calorie goal for you.

My thoughts exactly! I am not exercising either yet and I wonder the same thing. I am eating at about 1538 according to my TDEE. I was just about to post and ask if there was anyone NOT exercising and sticking to their TDEE.0 -
Also, in your example, if I ate 1784 and then burned 300 calories exercising, I'd still only be netting 1484 anyway. So how is that any different?
The difference is the fact that you're exercising. Exercise precipitates a whole host of hormonal responses and changes that push your body to maintain muscle mass and metabolism. This helps maintain metabolism and circulatory health.
If you do no exercise while losing weight, your metabolism slows rather dramatically, you lose a lot more muscle mass, etc.
Netting 1480 calories while exercising regularly is very different from netting 1480 while not exercising.0 -
Wow, so we are very similar then. Is 1538 your TDEE - 20%?No. 1484 is a perfectly appropriate calorie goal for you.

Well it is the truth. Exercise is not required in order to lose weight. I never said you shouldn't exercise. And I also never said why I'm not exercising.

Yes, I could eat at a lower deficit - but with it being so close - I'm curious if it even matters right now.
Being slightly below isn't a big deal really...plus, if you use the Katch McCardle formula you're going to get a somewhat lower number than that anyway. It's when people have a BMR of 1400 but they're netting like 700 calories that it becomes a big problem.0 -
I will be starting to work with some hand weights at home - about 20 minutes, 3 times per week. That is all I can do right now.

I look at it this way -
BMR is coma calories - what you would need to sustain basic functions if you were in a coma. You are not in a coma, even at sedentary (which if you are doing any exercise at all, then I'd say you are not sedentary). So considering that you are lightly active, or even sedentary, it's above coma activity, so your body deserves and needs more than your BMR, certainly not less.
A 15% cut puts you at 1577, barely over BMR. 10% gives you 1670.
From the things I've read, no one should be eating below BMR unless they are well over 200lbs and have a lot to lose, and even then only for a short time.
In my own experience, I've had much better results with eating well above my BMR, but still below TDEE - the fat loss has been wonderful. I've hit goal weight but still want to lower body fat percentage a bit, so am eating at about 10% below TDEE (often more), and I'm still getting results. I feel good, I'm looking better than I have in years, and it's really been quite easy. Slow and steady, yes, but I can do this for life.0 -

Um, I don't believe that is correct. The scooby calculator is an example - the activity level is based on your daily activity AND exercise level - it includes the exercise calories in the calculation.
MFP doesn't include the exercise.

what is recommended is to cut to 10-15% of your tdee. you only do a 20-25% tdee cut if you are above 35% in body fat.0

TDEE is a combination of BMR and activity (and two other very small factors we don't need to mention).
If you're completely sedentary, your TDEE is roughly BMR * 1.2. If you do 300 calories of exercise, your TDEE for that day is roughly BMR * 1.2 + 300.
"Sedentary TDEE" means "TDEE with zero exercise." If you use that as your starting point, you need to eat back exercise calories because they weren't included in your TDEE calculation.0 -
yo debo de comer 1200 cal para perder 15 kilos eso me marco mfp!! y ejercitar minimo 3 horas a la semana! es muy poco entonces????0

The TDEE calculator calculates your BMR and your Lifestyle and puts those numbers together, if you add exercise you need to add those calories, so it doesn't count the exercise calories, it uses your daily lifestyle, how much energy you use in a day..that's it!0

Here is another example:
http://www.fitnessfrog.com/calculators/tdee-calculator.html
Activity levels are based on exercise - so those calories are included in the number you get and you're not supposed to eat them back.
TDEE is a combination of BMR and activity (and two other very small factors we don't need to mention).
If you're completely sedentary, your TDEE is roughly BMR * 1.2. If you do 300 calories of exercise, your TDEE for that day is roughly BMR * 1.2 + 300.
"Sedentary TDEE" means "TDEE with zero exercise." If you use that as your starting point, you need to eat back exercise calories because they weren't included in your TDEE calculation.
But you said that you shouldn't eat at 20% deficit if you are sedentary and not exercising.
My question was why would these calculators even give you a tdee-20% calculation for sedentary, if you shouldn't do that much of a deficit? It doesn't make sense to me that they are just "assuming" that I will exercise on top of that number. If they wanted me to exercise, then sedentary shouldn't even be an option. Do you know what I'm saying?
I want to point out that I'm not arguing with any of the advice being given here. But I see a lot of advice thrown around without an explanation behind it. If I am going to follow the advice of someone - I want to understand the reasoning behind why I should be doing something.0
