With all the different BMR calculators…

How do you calculate what your actual BMR is? I was thinking of taking the average of the 3 I know of, but I'm unsure of what to do.

Bump ?

Here is the generally accepted formula to calculate your BMR.

Women: BMR = 655 + ( 4.35 x weight in pounds ) + ( 4.7 x height in inches ) - ( 4.7 x age in years )

How ever no one person is the same therefore using one formula for ever single person isn't an exact science but you really shouldn't see a dramatic difference (+/- 100 Cal) between that different BMR calculators.

Which ones have you seen and how do they differ?

I've used this one and I like it: http://www.freedieting.com/tools/calorie_calculator.htm
I like that it gives you a choice of which formula it will use, and it also provides a convenient zig-zag schedule.

You can probably ignore a lot of calcualtors that don't ask very much info from you. The less data they have as input, the less precise the answer will be.

Both came out dramatically different…

In the one nehushtan posted, make sure you change the "Exercise Level" drop down to Basal Metabolic Rate. I calculated using both formulas and they were about 60 calories away from each other - close enough to be accurate for my purposes.

Yeah I changed that and it helped a little, but then I did the calculator with my body fat % and it was around a 165 cal difference
