## Calculating RMR with equations...

hey there, i'm developing a site and basically I need to calculate a person's RMR by equation (height, age, weight, and gender).. but I've read a few articles dated a couple years ago that have stated sometimes these equations can be innacurate and overestimate/underestimate creating for a possibility of up to a 900 calorie innaccuracy (which could really throw a person's diet off and send them in the wrong direction)...

So what I'm wondering, is there any other newer equations possibly that are accurate for calculating RMR. What I'm planning on doing is having the coding calculate their RMR and notify them that it COULD be off by 10-15% and that they should get it manually tested with an oxygen test and they can input it themselves directly...

But, obviously it'd be best if I had a full proof equation that would be nearly perfect with only a 1-3% error margin.

Crap, I had a response and went to edit one thing and deleted it........

I'll come back to this, it wasn't a biggie......gotta run, lol.......

3. 1. divide weight by 2.2 to get weight in kg.
2. take weight in kg and multiply by 24.

thats gives you your BMR or RMR as you call it.

well.. theres a more specific equation that i'm using.. but the point of this thread being, i read an article that was dated several years ago that used an equation for RMR on a hundred or so people, and then they were actually tested with oxygen tests and the equations were off 10-15%, and that could throw a diet off.

i'm wondering now if there is a new method / equation of obtaining more accurate results.

that is about as accurate as your going to get. people's body composition are different in every person therefore it's sometimes hard to apply oxygen tests to your RMR as thier diastolic and systolic rates played a big role in inhibiting the accuracy of the oxygen tests. Just do what was stated and toggle with the diet as you see results.
