This study examined the relationship between dietary intake and changes in participants’ (N = 39) body composition during National Outdoor Leadership School courses. Body composition, height, and weight were measured pre- and posttrip. Participants completed food logs to record daily dietary intake. Changes in anthropometric measurements were analyzed using a paired samples t test. Correlation analyses were conducted to examine relationships between dietary intake parameters and anthropometric changes. Males lost an average of 3.4 (SD = 3.7) kg of weight and females lost 0.10 (SD = 1.6) kg. Males lost an average of 3.7 (SD = 2.7) kg of body fat and females lost an average of 1.5 (SD = 1.9) kg. In contrast, females showed greater gains in lean mass (1.5 ± 1.1 kg) than males (0.32 ± 2.3 kg) did. Average caloric intake for the total sample was 2,865.7 kcal/day (SD = 691.2). Overall, findings indicate that retention of lean body mass may have been due to both adequate carbohydrate and protein intake.
