BMR changes

Ok, so I went in to change around some of my goal settings and to check my BMR....My BMR has gone from a 2240 down to 1755, this calculated from MFP calculator. But in my actual goal area where I change my cal intake and my workouts it shows my BMR as 2190.....so which is it, both are provided here? Cause this is the issue that I have about the deficit in calories. If I follow the 1755 and eat 1200 cals and then the 475 cals I exercise I have a very small deficit in my Basal Metobolic Rate, less than a pound a week.........if I don't eat the exercise cals then I will have 1 pound. And thus the question "To eat or not to eat" comes into play again.

I have sent the question to technical help, hoping Mike can help me figure out which one is right. Because when I do my BMR in other sites it ranges between these 2 numbers. If I do the calcs myself it is still quite a bit lower then the 2190 here......Just wondering if anyone else notices this issue....or if you knew about it.

    you need to redo your goals, I don't think they change automatically on here (it's been a long time for me since I redid my goals so I can't be sure, but I think that's true).

    I used to do it every 10 lbs or so.

    Congratz on the change by the way, that's great!

    I did that and its still showing 2 different #'s. And based on what the calculator says and the goals page says there is a difference of 435 cals. I would be maintaining my current weight instead of having a deficit, unless I don't eat my exercise cals....it's like the left hand is not communicating with the right hand. I will have to follow that part of my eating myself to be sure I get the deficit I need. I noticed that there really was not a change in my loss. Bouncing around. Basically I maintained this week.

    Thanks for the info though.:flowerforyou:
  • I have a similar issue, but I think I understand why. Your BMR does not take into account your activity level. It only applies if you are sedentary all day long. If you selected "lightly active" for your activity level, then your number of calories burned through daily activity is greater than your BMR. This is because it factors in your "normal activity" level. Your BMR is based on your bodily measurements only.

    I am not absolutely certain of this theory, though. So if someone knows why the two numbers do not match and I'm clearly incorrect, please re-educate me. I'm going on the assumption that my "daily calories burned through normal activity" is more accurate than my BMR, thus giving me a 500 calorie daily deficit. Otherwise, just like Sassiebritches, if I strictly go by my BMR, then I'm never going to lose.

    One reason I believe my theory is correct is if you change your goals to reflect you want to "maintain" your daily calories will be higher than your BMR.

    Are you talking about your normal daily calorie burn? that's different from BMR. Because I didn't see any BMR section in goals. Maybe if you could show me exactly how you found that number in the goals section.

    BMR is the number of calories your body needs to function at a bare minimum (If you were in a coma and your metabolism were in a diminished state). The number of calories you burned from normal daily activity should be higher then what you are eating (hence the deficit).

    For people in the overweight and healthy BMI category, you should never eat less then your BMR, but for people with higher Body Mass Indexes (generally) you can safely go a little lower if you want to, as long as you continue to feel ok while doing so.

    Your BMR is found in the "tools" section. All it takes is your height, weight, age and gender and it gives you a number. Mine is 1390. However, in my goals, my daily calories burned is 1890. I am on a 1390 calorie allotment per day.

    FYI, of all the BMR calculators I've used online, the MFP one gives me the lowest number.

    I have been a bit worried over the last nearly 3 weeks at not seeing a loss because I wasn't sure if I was eating too much or too little. I was on 1200 cals per day. I decided to eat more and see if it helps. If no progress by the middle of March, then I'll really need to re-evaluate what I'm doing.

    I tested this BMR theory in several sites, giving my age, height, weight and activity level and I am still alot lower then what MFP has calculated in the Goals area where Banks mentioned it is the Normal Activity spot (sorry should have been clear). Most the BMR's all over have put me at 1850 or less and MFP has me at 2190

    just confusing.

    are you sure it is BMR? I have 2 numbers here.
    BMR is based on resting without doing anything (1230)
    the other rate is where you put in your activity is a different number because it is what you burn doing regular activity thru out the day (1650)

    In that case, it is because in the goals, where it says "daily calories burned through normal activities" that number is NOT your BMR. Your BMR is actually lower than that. But you burn more than your BMR every single day just by putting on your clothes, going to work and doing normal stuff. I think that's where the confusion is. Your actual BMR is the absolute minimum required daily. But you still have to eat more than the minimum if you're not lying in bed 24/7.

    So now to clear the confusion for me, what is your "daily calories burned through normal activities" and what is your BMR (in the tools section)?
