Abstract

This study compared, in Māori at risk of type 2 diabetes, advice emphasizing fiber rich carbohydrate and fat reduction and a high protein diet incorporating food preferences of indigenous people, with a control group. The researchers randomised 84 Māori to three study groups: consecutive 8-week periods of supervised bodyweight loss, supervised bodyweight maintenance and unsupervised adherence to prescribed diets that emphasised fibre-rich carbohydrate and fat reduction and high protein using culturally sensitive methods. Compared with controls, the high protein and fibre-rich carbohydrate/fat reduction diets were associated with reductions in bodyweight, while only the high protein diet was associated with reductions in total body fat and waist circumference; diet records indicated that compliance to the high protein diet was reasonable. In the fibre-rich carbohydrate/fat reduction diet, carbohydrate intake, but not dietary fibre, increased at the expense of fat.
