Summary
Brief summary
High protein diets are popular among Maori, especially on the East Coast of the North Island. The purpose of this study was to compare the metabolic effects of a moderate carbohydrate, high protein diet (MCHP) with a high carbohydrate-high fibre (HCHF) diet on insulin sensitivity in Maori at increased risk of developing diabetes and cardiovascular disease.
