Default Non-caliper bodyfat measurement

For those who want a non-caliper method for estimating bodyfat percentage (that's not the BMI method in Rapid Fat Loss or A Guide to Flexible Dieting).

Surprising to me the first and second gave me reasonably decent estimates. I don't remember if I tried the third.

Lyle these are great, but my problem is the variety of percentages you get with each equation, so which one is correct? Based upon your experience, which equation do you utilize with your clients or recommend?

Hey Lyle,
If you use calipers but dont use estimation equations, then how can you determine the figures? Also, how does one waist circumference measurement determine how much fat is on the rest of the body? Must be more factored into this then what is shown. Thanks.

Because individual's fat patterning is different, relative caliper measurements at specific trouble spots can be more useful than making up a % number based on an equation that kinda-sorta works on populations.

If the caliper numbers are going down, then goodness is occurring. For instance, I only use a mirror and an ab caliper reading.

If my ab caliper reading is 11mm I am fat. If its headed towards 4mm, I am getting leaner. I really don't care about the back of my tricep or my thighs, there is never appreciable fat there on me.

The first one told me I'm at 20%, the second didn't work and the third told me I'm at 27%. I'm trying to calculate my bf% for RFL and all I have to go on are tape measurements and my Tanita scale. It says 25% in the morning after I pee and in the evening before I go to bed 23%. Which would be a safer number to go with for determining protein intake?

I'm 29, 5'3", 123.8 lbs (yesterday), 27" waist, and unfortunately, don't have any pictures recently to post up to help.

Any idea? Would it be safer to err on the higher side to prevent losing muscle?

I think if you sit down and work through teh recommendations based on those different BF%ages at your weight, the difference in protein recs will amount to maybe 10-15 grams of protein.

To white: if you calcaulte nean body mass at 23% vs. 27% at your weight it ranges from 98-103 lbs and when you multiply that by the protein values, the difference in daily intake adds up to 3/5ths of it doesn't matter.
