The effect of replacing rapidly digestible starch with Fibersym® resistant wheat starch was investigated using a randomized, cross‐over study design. Following an overnight fast, 27 healthy adults (aged 23±2 years with a BMI of 23.0±3.0 kg/m 2 ) consumed a fixed‐amount meal of breakfast (muffins) that provided either 2g (control) or 24g (RS) of dietary fiber. The control breakfast provided 777kcal and the RS breakfast 693kcal. Baseline appetite questionnaires and plasma samples were collected and at regular time points for 240 minutes following the breakfast meal. Plasma samples were analyzed for glucose and insulin, ghrelin and GLP‐1. After the final blood draw an ad libitum meal was provided and the amount eaten recorded. Following the lunch meal, food intake was recorded using a food log and hourly appetite questionnaires were collected for the rest of the day. There was no effect of treatment on subjective appetite, plasma glucose, insulin or satiety hormones (>0.05). However, there was a statistically significant effect of treatment on food intake which was 178 kcal lower following the RS breakfast (p<0.05) These results indicate that replacing rapidly digestible starch with resistant wheat starch decreases meal caloric density, which may result in decreased total caloric intake for the day.
