As the worldwide obesity epidemic perseveres, efforts to identify ingredients that can aid in weight loss are heightened. A small reduction in fat mass can reduce chronic disease incidence and improve metabolic outcomes in overweight individuals. High‐amylose maize resistant starch 2 (HAM‐RS2) is a functional ingredient rich in fiber that may influence satiety and body composition. The aim of this study was to determine the effect of HAM‐RS2 on satiety and body composition using a randomized‐controlled, double‐blind design. Twenty healthy, overweight (BMI 蠅 27) adults (17 female, 3 male) were recruited. Participants consumed either the treatment (n = 13) with 30 g HAM‐RS2, or placebo (n = 7) with fully‐digestible starch, daily for six weeks in muffins. Subjective satiety, using a visual analogue scale, and body composition, using anthropometrics and dual‐energy x‐ray absorptiometry (DXA), were measured at baseline and week six. A decrease in waist‐to‐hip ratio (‐0.0310, P = 0.019), but increase in hip circumference (3.5146 cm, P = 0.033) occurred from baseline to week six in the HAM‐RS2 group. Reductions in trunk fat mass, android fat mass, and fasting blood glucose also resulted from HAM‐RS2 consumption. No significant changes in body composition or subjective satiety from baseline to week six were found between groups. HAM‐RS2 appears to favorably shift fat mass patterns which may influence metabolic outcomes.
