I'm trying to find that calorie calculator that incorporate body fat % to make the daily calories needed more accurate. I thought I saw it on T-Nation.com but now I can't find it anywhere. I've also seen it posted in forums but of course, I can't find it when I want it. Maybe you buys can help me. Thanks.

It's not clear exactly what your asking for here but if your looking for an internet tool to log and calculate you daily calories/macros.... www.fitday.com.

Unless someone is really obese, the difference in calculating BMR based to total mass or fat free mass will be very, very negligible.

A lb of fat burns about 2 cal per day, So whether you carry 30 lbs of fat or 10, the difference is what, 40 calories? sweet...

I thought I saw a calorie calculator that incorporates your bodyfat% to get a more accurate reading. I thought I saw it in one of the articles but now I can't find it. Has anyone come across this?

I think you know that metabolism is not quite that simple JMo..

OP the most simple way to calculate a ball park approximation of BMR from FFM is to multiply it by 10. Remember though BMR is not the amount of calories you need to maintain.

In case you are asking how to calculate FFM from your weight and bodyfat percentage:

If you are 15%, you multiply your weight by 0.15 which gives you your fat mass - which you'd then subtract for your FFM.

If you were 33% bodyfat, you multiply 0.33. 8% would be 0.08.

You might find this of interest - i am not telling you to try to prove shit - just as it is on topic and you are an educated poster.

Fear no more OP for I have come to rescue you

The calculator you're talking about was in Berardi's Massive Eating

Here is the calculator : http://www.johnberardi.com/updates/july262002/na_masscalculator.htm

Try this reading the info at this link (scroll down about half way). It'll talk about the Harris-Benedict Formula and the one I think you want, the Katch-McArdle Formula. However, as it's been pointed out, the difference is minimal. For me it's the difference between a BMR of 1836 and 1879.

I find Berardi's calculator hard to believe. In the section labelled "exercise sessions". Is that PER DAY? If that's the case, I can see why the number is so high.
