5.6%.
My only sources of fat were the olive oil I sauted with, the 2 - 3 eggs I had each morning, and a few slices of cheese (swiss or ex sharp cheddar). I drank powdered milk (which has no fat or cholesterol in it), water, and vegetable juice and ate only pasta, white jasmine rice, and various frozen fish. It may have gone a little lower: at some point I began seeing a faint line between the long and lateral heads of my triceps going all the way up the length of my arm terminating at the deltoid.
I was unemployed and trying to conserve funds. My diet has since expanded. Bodyfat was 7.2 % this morning according to my FatTrack II calipers.
If you want to lose some body fat I would have a look at High Intensity Interval Training aka "HIIT" (not to be confused with HIT ala Mentzer/Jones/Darden). I have not done enough research to conclude that HIIT absolutely causes superior b-fat loss, but the few articles I have dug up seem to indicate that it would:
hGH / Somatotropin "profoundly" influences lipid and carbohydrate metabolism:

Aerobic exercise intensity is positively linearly correlated to hGH / Somatotropin release:

HIIT burns several times the amount of fat than endurance style training when corrected for energy expenditure (its more efficient):

If you do running HIIT, at the very least you may improve your verbal IQ:

Article from the LA Times discussing HIIT with some anecodotal info:

My own interest in using HIIT is to lower my heart rate, improve my general fitness, and give me an excuse to do lots of swimming. I haven't found anything about its potential effect on muscle fiber or recovery so I'm still concerned about its impact on gains and overtraining risk.
The author of Natural Hormonal Enhancement recommends using HIIT on your off days to keep as much hGH circulating in your body for as long as you can during the week (lifting will secret hGH on non-HIIT days). The recommendation is on page 76 of the PDF or page 308 of the actual book. Here is the link, there are lots of references for the research junkie:

You could also try supplementation using linoleic acid (sp?). Results in human studies are varied and in one study it was shown to interfere with the functioning of endothelial tissue (stuff that lines your veins and what not). I didn't take down any citations because that last bit on the endothelial tissue put linoleic acid past my "risk tolerance", so to speak.
