Dr. Barry Sears Dr. Sears Comments:

There were two real problems with this study. First, the diet intervention was for only five weeks, which is too short of a time to see a significant difference when viewing the glycemic load alone.  Second is that it is the protein to glycemic load, not the glycemic load itself that makes a significant difference in blood chemistry as demonstrated 15 years ago at Harvard Medical School (Ludwig et al, Pediatrics 103:E26 (1999).  I guess they forgot to read that study.
