The effect of different snack foods on fat mass/distribution, glucose and insulin were assessed. Thirty‐five adult men and women (age: 36.5 + 11.4, BMI: 32.8 + 7.1 kg/m 2 ) consumed a whole food (dried plums) or refined (low‐fat muffins) snack twice daily for eight weeks. Test foods provided 100 kcal per feeding and were similar in macronutrients but differed in fiber and other food constituents. Body composition and fat distribution were assessed at zero and eight weeks via bioelectrical impedance analysis, air displacement plethysmography, and dual x‐ray absorptiometry, which were used to estimate total fat mass via a four‐compartment model. Blood was collected at baseline and eight weeks and analyzed for glucose and insulin. Fat mass and android:gynoid fat distribution tended to be lower in the dried plum intervention, ( p =.06 and.08, respectively), while no effects on total body weight were detected. Glucose was elevated ( p < .05) during the muffin trial with no difference observed for the dried plum trial. No difference was observed for fasting insulin within or between groups. Results demonstrate that dried plums may be advantageous at promoting positive alterations in body composition and glycemia. Grant Funding Source : Supported by the California Dried Plum Board
