A behavioural intervention incorporating specific glycaemic index goals improves dietary quality, weight control and glycaemic control in adults with XXXX 2 @entity6 .

@entity1 @entity164 @entity6
OBJECTIVE: A lower glycaemic index (GI) diet is associated with a reduction in glycosylated Hb (HbA(1c)) in @entity1 with @entity6 . Yet, little research has been conducted to determine the effects of specific goals regarding consumption of low GI (LGI) foods on @entity6 outcomes. The present study evaluated a behavioural intervention on dietary intake, weight status and HbA(1c), which included a goal to consume either six or eight servings of LGI foods daily. DESIGN: A parallel two-group design was used. Following the 5-week intervention, @entity1 were randomly assigned to the group of six (n 15) or eight (n 20) servings of LGI foods daily and followed up for 8 weeks. Dietary intake was assessed using the mean of 4 d food records. SETTING: A metropolitan community in the USA. SUBJECTS: Individuals aged 40-65 years with @entity164 2 @entity6 of >= 1 year and HbA(1c) >=  7  0 % were eligible. RESULTS: There was no significant difference between goal difficulty groups with regard to GI servings at the end of the study. However, mean consumption of LGI foods increased by 2  05 (SE 0  47) and 1  65 (SE 0  40) servings per 4184 kJ in the six (P < 0  001) and eight (P < 0  001) LGI serving groups, respectively. For all @entity1 combined, there were significant decreases in mean HbA(1c) (-0  58 (SE 0  21) %; P = 0  01), weight (-2  30 (SE 0  78) kg; P = 0  01), BMI (-0  80 (SE 0  29) kg/m(2); P = 0  01) and waist circumference (-2  36 (SE 0  81) cm; P = 0  01). CONCLUSIONS: An intervention including a specific goal to consume six to eight servings of LGI foods daily can improve @entity6 outcomes. Clinicians should help @entity1 set specific targets for dietary change and identify ways of achieving those goals.
