Bmr of ~1800 yet MFP says 1490 daily?

Okay.` I'm still epically confused.
I've been here about a week, and done a lot of reading around the forums, and associated sites. stuff like BMR BMI TDEE NET and stuff are all completely new to me. Now, I'm not the brightest crayon in in the box, but something here does not add up.
Everywhere, people say do not eat below you basal Metabolic rate. This is what I need as a minimum about of calories to keep my body functioning correctly, right?
Ive tried several different websites and several different formulas, and they all come out with different totals for my BMR. Mfp says 1797, fitnessfrog says 1838. All reasonably around the same area.
To get the upper limit I must times my BMR by 1.2 to get 2150. I do not take much exercise cept a half hour walk everyday and swimming and badminton a couple of times a week. In order to lose weight -safely- I have to eat between these numbers. Ive seen poeple recommend about 150 cals above bmr in order to keep metabolism up and running nicely.
yet mfp says I should be eating 1490 cals a day. This seems below the minimum I need to exist!
Does this have something to do with NET and eating exercise calories back? I'm only getting back about 150 kcals a day execise and even if i eat all these back I still don't net above my bmr, even according to mfp.
Someone check my maths, or tell me what I'm overlooking. Or should i go to someone professional?
Stats: 168cm (5'6'') 105kg (228lbs) body fat 56.3%
ETA: this is set to lose 1.5 lbs a week.
I have a goal of losing over 100lbs to lose. Maybe this is too much to do in one go and is screwing the numbers up? I am growing to like this site very much, but increasingly questioning its accuracy is leading me to doubt its doing me any good!
thanks for the assistance,

1. Rule #1 do not ever eat below your BMR
2. Rule #2 do not ever fail to follow rule #1
Any questions!

I'm not certain b/c I'm a little confused....what are your goals set to? If it's set to lose 1lb, you'll be eating about 500 cals less than the total calories your body needs to maintain your weight every day. I think. if it's set to 2lbs a week, I believe it would be another 500 cals less. But I'm not sure, that's just how I understand it.
Your BMR is the calories your body needs to run your organs, it doesn't include the extra calories your burn working out during the day. So you should never eat less then your BMR to lose weight safely and longterm0 -
My stats are similar to yours... 5'7 tall and started at 242 lb, now about 229 lb.
MFP set my calorie intake at 1750 which seems about right for me - that was based on my setting of want to loose about 1 lb per week.
Some weeks I loose 1 lb, some I loose none and occassionally I loose 2 lb.
1490 sounds low to me, but could be based on what you set as your weekly weight loss goal - try adjusting it to 1lb per week and see what you get.0 -
target of 1.5lbs a week. From what I've read, its sensible for someone morbidly obese (me)
Maybe if I aim for 1 per week and hope I get two? :P Wouldnt surprise me with my body tbh!0 -
i thin you need to try a level for a few weeks and see how it works for you and adjust. I think my organs are working just fine on 1200 cals (plus exercise cals up to about 1500) and I have lost 23 lbs in about 2 months. No one has the answer, there are indeed many answers.0

What is BMR?0

BMR is ajoke, don't worry about it.
Your goal is WEIGHT LOSS, produce those results and don't worry about anything else, a safe range to shoot for is 1-2lbs a week.
Here's the kicker, As you lose weight your BMR will go down... so who cares if you eat slightly below it. It will be your NEW BMR eventually.
define slightly please
Set with 2lbs loss a week, its 1200. a difference of 600 kcals (not including execise expenditure) does not seem slight to me.0 -
If you are Obese then you can eat below your BMR for a short while.
I would set your weight lose to 1 lb per week.
See where and how that works out for you.
Make sure you measure yourself as well as just not only weigh.
some times people have to adjust it a few times on there journey to get the results they need.0 -

Thats a good point. One of my problems with a new project is going off at 100 miles an hour lol
I'm going to see what happens for a couple of months, and then readjust. Good idea.0 -
I'll have to disagree with some of the posts based on my experiences so far. I initially started by eating below my BMR. I had some fast weight loss and it was going great. Recently I just hit a brick wall, so I really started doing some major research. I've always been familiar with the term BMR, but did not understand it properly. I always though BMR was what I wanted to be at to lo lose weight. Not at all the case. Recently, I discovered a new number called TDEE.
You need to now your BMR and TDEE. Look them up and you'll figure it out. You are going to want to manually set your MFP goals to a number between these two ranges. I would also recommend doing some research on carb-protein-fat ratios and decide for yourself what percentage to put into those categories. I personally found it better to lower the carbs below MFP settings and raise the proteins and fats. You will want to make your own judgement call on that one.
So, figure out that TDEE and BMR. Set a goal based on that range. Yes, you can lose weight eating below your BMR, but I've honestly found that to be making it harder on yourself with only an initial pay off. I recommend you go to Fat2Fitradio.com . There is some excellent information there that really made sense to me.0 -
Everywhere, people say do not eat below you basal Metabolic rate. This is what I need as a minimum about of calories to keep my body functioning correctly, right?
That is an estimate of the number of calories that will be used by your body's basic functions, yes. They can be withdrawn from fat reserves or from food, for example in the middle of the night your 60 calories/hr or whatever isn't coming from food.
By "Everywhere" I guess you mean "on here". I had never heard this "don't eat below your BMR" opinion before coming on here. I've read a lot of stuff too.
"Don't eat below your BMR" is not part of the site's goal setting calculations.0 -

If you google "Don't eat below BMR" you'll find other sites that say the same thing,
Again, I don't know if it's just members heresay, or whether there's any actual science behind it, bit it's not just MFP members that advocate this.0 -
This might become my standard response because it makes so much sense to me... Here is how I think of weight loss, eating the right amount of calories and how that relates to BMR and TDEE.
I want to lose 12 lbs, which at 3500 calories/lb I have 42,000 calories in storage that I want my body to use up and get rid of.
I use 1600 calories a day just pumping blood, breathing, organ function (BMR) and another 1000 calories a day in exercise and moving around (walking to my car, cooking dinner, etc), so I burn a total of 2600 calories (TDEE).
If I want my body to use some of the calories from my storage of 42,000, I have to feed it less calories than I burn in a day. So when I eat about 2200 calories a day, then my body uses 400 calories a day from my storage to cover all of my activity of 2600 calories. That means my 'storage' or extra 12 lbs is being whittled away at 400 calories a day.0 -

That.. made sense! Thank yoU!
But what if you do extra effort: how much of that dyou eat back to stop your body freaking out at your for trying to kill it? :P0 -
It depends on how aggressive you are about your goal. Your net calories should always be about the same. For example,This might become my standard response because it makes so much sense to me...

My BMR is 2240 (appx), My goal is -2 lbs a week.
To accomplish that, I need to consume 1240 cals/ daily (deficit of 500 cals per Lb per day)
If I exercise 300 calories, that would put me at 940 cals (1240 - 300)
It's advisable to eat back your exercise calories.. (940+300 more cals= 1240 net)
However you get to your net daily total is up to you, (exercise vs fewer calories vs combination of both)
I hope this helps0 -

He's right. You don't have to eat above your BMR. You will live and you will lose weight. HOWEVER...if you want to keep the weight off once you reach your goal, i highly suggest eating at your BMR at least. Eating at too low a calorie deficit for too long will condition your metabolism to that amount of calories. I say eat at your BMR if you want to live a healthy lifestyle. If you want to become a yo yo dieter then eat your calories as low as you want.0 -

I'm sorry, but I completely disagree. If more people paid a bit of attention to BMR and TDEE - perhaps there wouldn't be so many people eating 1200 calories (or less) a day and asking "Why can't I seem to lose any weight?". While it may not be an exact science or perfect every time, saying it is a "joke" is doing a lot of people a disservice. And honestly, even if it IS a guess -- is it really hurting people to have more information about their own bodies. Absolutely not.
And telling people that it won't matter if you eat under your current BMR because your BMR will go down, so eventually it'll be your new BMR is once again doing people a serious disservice. If your current BMR is 1800 - you need 1800 calories to live RIGHT NOW. Who the heck cares if you'll only need 1300 when you're thinner? You need to give your body what it needs NOW and stop worrying about what'll happen to it in a week or two or whatever.0 -
I am 5 ft 3 and weight 117kg (over 260 pounds) and have found I need to eat close to my BMR (I eat 1600 cals per day) in order to lose weight as I have yo'yo dieted in the past and can be a couch potato at times.
I always eats back as many of my exercise calories as I can to protect my BMR
There is also a group here 'Eat for the Future You' whereby if you are quite active (I have tried this regime but need to up my exercise I think) whereby you eat based on the TDEE of your GOAL weight (but never below your current BMR) and in this way when you reach your goal weight you don't need to change your diet.
With this regime you have one goal calorie count per day and DON'T eat back any exercise calories.
My feeling is I will go back to this when I have lost a bit more weight and can be consistently burning 500 cals per workout at least 2-3 times a week as the beauty of it is that you have the exact same calorie goal every day regardless of exercise (mine was 1900 cals)0 -
i thin you need to try a level for a few weeks and see how it works for you and adjust. I think my organs are working just fine on 1200 cals (plus exercise cals up to about 1500) and I have lost 23 lbs in about 2 months. No one has the answer, there are indeed many answers.
I'm glad you said this. I went 6 weeks with a bmr of 1520 and I do 5 (60 min) classes a week and the treadmill with a speed of 3.0 and a varied incline up to a level 14 the other two days. I've been gaining and losing the same 3 pounds! I'm defined as "morbidly obese" so burning a min 450 x 5 per week and burning 250 x 2 per week...I think I'd have lost more than 3pounds.
So, we'll see how this goes...and more importantly...how I feel...0 -

Thats what confusing me! there are two (a million?!) ways of counting them, and it seems a matter of personal opinion which is best. I guess the only way i'll find out is to see which one works for me, and that can only answered by time.
Atm im still experimenting with everything - still havent found out how to exercise with no money >.< - so I will just keep reading
Thank you very much that was very helpful. And thank you everyone, all you're input is much appreciated.
I do feel better with execise, and I can eat anywhere between 1200 and 2000 per day with no trouble - guess my body is well trained huh? - but I think im going to go to a professional and get something for me sorted out 0
