Here is a before- and after- summary of the lab data for the 2004 Nutrition Think Tank, which was led by Dr. Ron Rosedale. Labs tests were generously donated by Esoterix Lab (now Nichols Lab, I think), and included a standard cholesterol panel plus more in-depth tests, such as for the hormones leptin and insulin. The before- and after- test results showed a significant improvement for people who stuck with the dietary program.
