Brief Summary

The present study sought to investigate the effects of acute dietary changes on estimates of body composition. Specifically, the impact of an acute high-carbohydrate diet (9 g/kg body weight of carbohydrate) and an acute very low-carbohydrate diet (1 - 1.5 g/kg body weight of carbohydrate) were examined.
