Protein and Polycystic Ovary Syndrome (PCOS)

Polycystic Ovary Syndrome (PCOS)

Polycystic ovary syndrome (PCOS) is a significant public health problem and is one of the most common hormonal disturbances affecting women of reproductive age. Women with PCOS are often insulin resistant, increasing their risk for cardiometabolic health problems (e.g., type 2 diabetes, heart disease, high blood pressure, sleep apnea, anxiety, depression, and stroke) especially if they are overweight. Lifestyle modifications, including dietary changes and regular physical activity, may alleviate metabolic dysfunction in women with PCOS and are often the first line of management for patients with PCOS. Several studies have identified protein as a key nutrient for regulation of energy balance, maintenance of skeletal muscle mass, and improving cardiometabolic health across the lifespan. However, the effect of increased protein intake (30% of total energy intake) on cardiometabolic health in women with PCOS has not been well-defined and mechanisms for these effects have not been identified. There is an evident need for well-designed, randomized controlled trials evaluating the efficacy of increased protein intake in women with PCOS on markers of cardiometabolic health. Preliminary data from collaborative projects with the investigators on this proposal suggest that increasing protein in the diet has the potential to improve markers of cardiometabolic health, potentially through improvements in body composition and/or changes in cortisol, energy metabolism, inflammation, and neurological regulators

Appetite Response to Meals With Different Protein Sources in Women With PCOS

Polycystic Ovary Syndrome (PCOS)

Polycystic ovary syndrome (PCOS) is a common endocrine disorder characterized by insulin resistance, hyperandrogenism, and reproductive dysfunction. Dietary strategies that improve postprandial insulin and glucose responses are central to managing metabolic symptoms in PCOS. Meals higher in protein can attenuate postprandial glycemia and enhance satiety, but the effects may vary by protein source. Animal sources of protein typically have higher essential amino acid content and insulinogenic potential, whereas plant proteins offer fiber and phytochemicals that may influence glycemic dynamics differently. Few studies have directly compared the acute metabolic effects of plant versus animal protein in women with PCOS. Given the distinct pathophysiology of PCOS, extrapolating findings from healthy populations may be misleading. Understanding protein-specific effects on postprandial insulin, glucose, and appetite-regulating hormones in this group is essential for targeted nutrition guidance. Additionally, plant-based diets are increasingly promoted for cardiometabolic health, but their acute effects in insulin-resistant women remain underexplored. This study will assess whether plant and animal protein meals elicit differential postprandial responses in women with PCOS. Findings may inform dietary recommendations aimed at improving metabolic outcomes in this high-risk population.
