What's your BMR?

140
5'1"
BMR: 1,359
diet: 1400

I'm sorry, I know this question is used and abused. I just can't wrap my head around how to use the results I'm getting. Also, I'm getting different BMRs from different calculators. How do I know what to follow in order to lose 1-1.5/week?

27 years old
227 lbs
62 inches tall

MFP says 1718 calories per day. Is this what I should aim for, or still deduct 500 calories in order to lose? Which doesn't seem right because 1200 calories at 227 lbs sounds like I would faint or be very crabby all the time.
FitnessMagazine.com says 2168 calories per day. I believe this includes the lifestyle factor (sedentary, desk job)
Cutthefatpodcast.com says 2465 calories per day also factoring in sedentary lifestyle.

Any help would be appreciated, tried posting this over the weekend but no responses. :embarassed:

Ok let me help clear this up a bit. MFP builds the deficit into your calories, so I think that 1700 it is giving you will have a deficit built in already, which is why it is lower than the other two calculations. Remember your BMR (base metabolic rate) is what you would burn if you did nothing all day, it just keeps your body going.

MFP then multiples that BMR by an activity factor (depending on your work) to arrive at your TDEE (Total Daily Energy Expenditure). You can see your TDEE on the Goals page on MFP under calories burned from normal daily activity. This is your calories burned without exercise.

When you set you goal weight loss per week MFP creates a percentage deficit to your TDEE that will allow you to achieve this. This percentage will vary depending on your overall size (much bigger people can handle larger deficits then already lean people) and you rate of weight loss. Normally 20% - 30% deficit on your TDEE is correct.

So with your stats your BMR is about 1800 (don't get too hung up on exact numbers, rounding is fine)
If we assume you have a sedentary lifestyle, i.e. are an office worker we times that by the activity factor 1.2. Making your TDEE 2160.
Then we create a deficit of 20% (2160 x .8) = 1728. This is the calories you can eat, before exercise. You can then decide how many of your exercise calories you want to eat back. E.g. on a day where you burn an extra 500 calories you may choose to eat half of them back, meaning you can now have 1978. Or all of them back if that is what works for you, as you are already in deficit Hope this helps somewhat!

Thank you so much for breaking it down, that totally makes more sense. Whew!!:happy:
