I've been on Atkins for almost 9 months now. I didn't weight until afetr the first 2 weeks...I weighed 315 at that time. I know I was at least 320 when I started, maybe even as high as 330. If I lost the same amount my first 2 weeks as I lost the third, I was 325. I didn't get the book until 3 weeks in...so, I didn't know to have tests done. As result, I do not have any starting numbers. But, I had my blood drawn a few weeks ago:

Cholesterol -- 175
LDL -- 122
VLDL -- 19
HDL -- 33*

Triglycerides -- 96
Blood Glucose -- 84

*My HDL is a few points below normal...But, considering I had just come off a diet high in grain [Grain Lowers HDL], with almost no meat [Saturated and possibly Monounsaturated Fats raise HDL], and with most of the little fat I ate coming from Trans and Polyunsaturated Fats [Both are known to lower HDL], my HDL was probably non-existent before going on Atkins.
