Background/Objective: A low starch/low dairy diet resulted in spontaneous conceptions in ten obese infertile women with Polycystic Ovary Syndrome (PCOS). 

Case Report: Through a retrospective chart review of a fertility clinic, ten obese infertile women with PCOS conceived spontaneously after switching to a low starch/low dairy diet. Spontaneous conceptions occurred without medications (no metformin, weight loss drugs or ovulation inducing medications), exercise or caloric/fat/ carbohydrate restrictions. The nutritional guide encouraged unlimited consumption of lean meats, non-starchy fruits and nonstarchy vegetables. Nuts and seeds were permitted for snacking as well as one ounce of full fat cheese daily. The group had an average BMI reduction of 2.6 points. All pregnancies were singleton gestations. 

Discussion: Variable presentations of PCOS symptoms and metabolic inflexibility have made finding an ideal dietary recommendation challenging for PCOS patients and for their health care providers. A low starch/low dairy diet may improve spontaneous ovulation and possible conception in obese infertile women with PCOS. Nutrition appears to play a pivotal role in improving ovulatory function and fertility potential in obese women with PCOS. 

Conclusion: Dietary intervention may be a simple and highly effective treatment for the metabolic and reproductive problems caused by PCOS. A low starch/low dairy nutritional plan may give clinicians an easily accessible and sustainable tool for treating obese PCOS patients who desire conception.
