Diet with Higher Protein-to-Carb Ratio Benefits Women with Polycystic Ovarian Syndrome
In a controlled, six-month trial involving 57 women with polycystic ovarian syndrome (PCOS), adherence to a high protein diet (>40% of energy from protein and 30% from fat) was found to be associated with greater weight loss (mean: 4.4 kg) and body fat loss (mean: 4.3 kg), as compared to women adhering to a standard protein diet (<15% of energy from protein and 30% from fat), after a period of 6 months. Furthermore, adherence to a high-protein diet was associated with greater reductions in glucose, even after adjusting for changes in weight. The authors conclude, "Replacement of carbohydrates with protein in ad libitum diets improves weight loss and improves glucose metabolism by an effect that seems to be independent of the weight loss and, thus, seems to offer an improved dietary treatment of PCOS women."
