I don't know what PCOS is, but I do know that 150 grams of carbohydrates per day is TOXIC to diabetics, and will guarantee not only the hastening of beta cell burnout but the promotion and aggravation of diabetic complications. The end stages of diabetes involves problems too hideous for me to even contemplate. It may be a workable way to weight loss, but if blood sugar control is one's primary focus, the "Insulin Resistance" diet merits only the trap door.
