A new study has determined that small dietary changes can make a big difference in risk, even without weight loss. This was found to be especially true among African-Americans.
In this study scientists had several groups, all people at high risk of diabetes, some who ate low fat and others who ate high-fat diets.
At eight weeks, the group on the lower fat diet had significantly higher insulin secretion and better glucose tolerance and tended to have higher insulin sensitivity.
Scientists say the results suggest that attention to diet quality not quantity can make a difference.
