Reproductive Hormonal Changes Following Two Types of Hypocaloric Diets in Overweight and Obese Polycystic Ovary Syndrome Women

Introduction: The appropriate combination and composition of hypocaloric diets for obese women with polycystic ovary syndrome (PCOS) is still unclear. The aim of this study was to investigate the effects of a high protein-low glycaemic load diet on reproductive hormones in obese women with PCOS. Materials and Methods: In this single blind clinical trial, sixty overweight and obese women with PCOS, not using metformin, were randomly assigned in one of two groups, the modified with a 30% protein-low glycaemic load diet, and the conventional with 15% protein. Reproductive hormones, glucose and insulin were measured for 49 subjects at baseline and after 12 weeks. Results: Weight loss showed no significant difference in the two groups. Changes in means for testosterone in the modified and conventional groups (0 to 12 weeks), were 1.78±1.52 to 1.31±1.27 and 1.51±0.63 to 1.15±0.57 ng/ml, respectively (p<0.001). FSH, LH, estradiol, progesterone and prolactin did not change. Insulin and HOMA reduction was significant for modified diet (p<0.001). Conclusion: Weight loss had a significant effect on reduction of androgens. The main effect of modified diet with high protein and low glycaemic load was observed on insulin and HOMA, a finding which should taken into consideration for women with PCOS.
