NCT00254124

Brief Summary

The purpose of this study was to determine whether a food portion control tool would be effective to result in weight loss in a group of overweight type 2 diabetics. We hypothesized that this tool would be effective to induce weight loss in these patients. We also hypothesized that diabetic control would be improved in patients using these plates.
