Effect of varying levels of carbohydrate diets on weight loss, ketone production, and urinary calcium excretion on overweight college students

This study determined outcomes of a low-carbohydrate (CHO) and moderate-CHO diet on weight loss, ketone production, and urinary calcium excretion in a convenience sample of 14 (ages 18-26, m=2, f=12) overweight students at a midwestern college for one month in a two-week, cross over study design. Results showed significant weight loss in subjects over time (p< .01). However, no significant difference between diet groups over time for weight loss was shown. Outcome of urine ketone production remained unaffected over time and between groups over time. A significant difference was noted in urinary calcium excretion within subjects over time (p=.035), yet not between groups over time. These findings suggest that weight loss may be due to a decrease in water and lean body mass from glycogen mobilization. Ketone production was unaffected possibly due to non-compliance with diet recommendations and small sample size of the study. Urinary calcium excretion increases may be attributed to higher protein intakes in participants on the modified-CHO diets, possibly allowing for a negative calcium balance in the body leading to premature osteoporosis. / Department of Family and Consumer Sciences
