figuring out bmr

rockerbabyy

when i use the BMR calculator here on the site, it says 1873/day

I was looking though an old notebook of mine (probably from 08 or 09) and found this:
655+(4.3*weight)+(4.7*height)-(4.7*age) = BMR
BMR * activity level = maintenance
-500 for 1lb/ week loss or -1000 for 2 lb/week

doing THAT math, i get 2614 as maintenance and 1614 to lose 2 lb/week. (unless im calculating activity level wrong.. i used 1.375 for lightly active)
MFP currently has me at 1550/day to lose 2 lb/week..

which would you go with? i know its not a huge difference in calories - i just want to be accurate. when i upped my calories from 1330 to 1550 i lost 3 lbs that week, when the week before i had gained 1.6...

2614 = TDEE not BMR
TDEE - 1000 = 2 lb weight loss

its a 64 calorie difference. you can always try 1614 for 2 weeks and see how your body responds or stick to 1550 since its working and wait till its not working anymore to raise it.

BMR and TDEE (aka maintenance) are 2 different things.

aah ok thanks for the clarification on that! i dont even remember where i got the formula or anything and i could have missed some stuff when i wrote it down.

I don't mean to diminish the importance of your question, but I think you really could go with either one, or a value in between the two, and be just fine.

Keep in mind that the Harris-Benedict formula is typically more accurate in lean individuals, and it also includes exercise as part of the activity factor. So in other words, HB formula is assuming that 2600 is your maintenance INCLUDING activity.

I actually went to three different websites figure out my BMR. My Fitness Pal calculates it at 1462 for me. For reference I am 5'3" at 169 pounds, 29, and MFP is seditary activity level.

I went to these sites BMI-calculator.com (to the BMR one), Health.discover.com (the BMR calculator), and fitwatch.com (the BMR calculator) to figure it out. I got the results in order of the sites listed: 1549.95, 1542.7, and 1543.

Sorry I don't know if your long hand calculation works.

edit: BMR is if you lay around all day doing NOTHING
