Obesity has increased significantly over the last 30 years, with racial/ethnic groups (RE) disproportionately affected. Few investigations have examined the effect of RE on hunger/satiety and food intake behavior. In a 2‐arm cross‐over study, we examined the relationship of body mass index (BMI) and RE to subjective satiety and snack intake using a modified preload paradigm with gum chewing (GUM) or no gum control (CTL) as a means to enhance the satiety response to lunch preload. Fifty unrestrained healthy weight and obese (1:1 ratio) women completed the study. RE: Caucasian, African America (AA), Asian, Hispanic, balanced between BMI groups. GUM compared to CTL resulted in significant suppression of hunger, desire to eat and prospective consumption (p<0.05 for all controlling for BMI and RE). Snack intake was marginally reduced by GUM (p=0.08). Post‐hoc analyses indicated significant (p<0.05) differences by RE on all subjective satiety measures, which corresponded to RE snack intake 3 h after lunch. Effects appeared to be specific to AA women and sweet snacks (p=0.003) and were not predicted by differences in insulin, glucose or CCK responses. These data offer new insight for understanding the influence of RE on satiety and snack intake. Grant Funding Source : Supported by Wrigley (A subsidiary of Mars Incorporated)
