Table 2 Dietary intakes and physical activities of women with polycystic ovary syndrome compared to eumenorrheic non hirsute controls following 12 and 24-week of energy restricted low glycemic index diet

From: Does a restricted energy low glycemic index diet have a different effect on overweight women with or without polycystic ovary syndrome?
