Also there was a significant difference in the average of energy and carbohydrate intake between 2 groups in the follicular phase which was statistically significant for fat intake between 2 groups in the luteal phase [P<0/05]. There was no difference in the average intake of energy and macronutrients between 2 phases in non PMS group.
