NCT01700868

Brief Summary

This study aims to test hypotheses that are potentially important to diabetes management, with practical implications for reducing the medical, personal, and economic costs of the disease. Anticipated outcomes include reductions in glycosylated hemoglobin that are significantly greater than those achievable with current diet recommendations, reductions in medication use among many intervention-group participants, beneficial changes in body weight and serum lipid concentrations, and a demonstration of the acceptability of the intervention diet. Progress toward these goals could refine dietary guidance for individuals with diabetes, increase treatment expectations, and reduce the massive burden the disease currently imposes. The study further attempts to translate a dietary intervention studied in a clinical research setting to a medical practice. This will contribute to developing a model for diabetes care that can be used widely.
