I haven't even had cholesterol tested in a few years, but last Feb had a CAC score of 14, not a perfect zero, but not bad for a 65 yo raised on Crisco crust pies, sugar, and later low fat vegetable oil laden processed foods. Also took large doses of calcium supplements the past 15 years until 2012, so surprised my arteries weren't lined with calcium worse than shown.

Between 2012-2014 I had four tests, one an NMR, which show a classic Low Carber profile:
TC ranged between 211-253. A bit high by normal labs, but not the "high" seen by some LCers.
Trigs between 20 (that was by NMR!) - 39, other two right near 30. Very low.
HDL between 85-118, the other two right near 100. Very high, so I claim my average Trig/HDL to be only .33. Both Trigs dropped and HDL climbed within the first year of LC and have stayed solidly in this range for five years.
LDL has been 103- 155. The 155 was the NMR, which had an LDL-P of 1197 and Small LDL-P of 148, or 12% small LDL.

All seems pretty average for a long term low carber, some numbers out of standard lab ranges, but a stellar Trig/HDL ratio. Even my GP is OK with the 250 TC because she understands the Trig/HDL ratio and follows new ACC guidelines on LDL...not to worry until 190.
