Dietary intake was assessed with a semi-quantitative food frequency questionnaire that consisted of 147 foods and beverages (with standard serving sizes commonly consumed by Iranians. We constructed the DASH score based on 8 foods and nutrients. FM and FFM indexes defined based on fat mass and free fat mass. Results: Obese individuals with more adherence to DASH diet had lower FFMI (P=0.04). Lowe trunk fat was strongly associated to more adherence to DASH diet (P=0.02). Moreover, individuals those had more adherence to DASH diet had lower waist circumference (P=0.03). Conclusions: The current study suggests that adherence to DASH diet is highly associated with weight loss in obese individuals and may be associated to FMI and FFMI which is depended to sex.
