Optimal gestational weight gain is a critical determinant of both fetal health and pregnancy outcomes. A randomized behavioral intervention with recommendations to consume a high fiber diet was conducted to investigate its effects on gestational weight gain. Participants were 36 pregnant women (mean± SE, Age 31±0.7 years, BMI 30±1.1kg/m 2 ) randomized to an assessment‐only control group or to intervention groups provided with either a high‐fiber cereal (CF) or resistant starch (RS). Support for the intervention groups included weekly emails or phone calls with a weight loss counselor and regular self‐monitoring of body weight. A total of 10 controls, 13 CF, and 13 RS participants completed the study. All groups gained more than the Institute of Medicine maximum recommendations with the CF group gaining the most (139 + 10% of maximum recommended weight, mean + SE), and the RS group gaining the least (119 + 13%). Weight gain in both intervention groups was neither significantly different from the control group (129 + 35%, P=.50, main effect) nor from each other (P=.18). Percent weight gain was more variable in the control group (35% vs. CF=10%, RS=13%, SE, P=.02). Neither parity, intervention engagement score, nor counseling by their healthcare providers predicted percent weight gain. Preventing excess gestational weight gain is challenging, and was not significantly attenuated with recommendations to increase fiber intake with provided fiber sources in this pilot study.
