Study Notes

Hepatic Steatosis

Ectopic fat storage in the liver is called hepatic steatosis.
It can progress to nonalcoholic fatty liver disease.

PCOS & Body Fat

Normal-weight women with PCOS have increased total abdominal fat mass.
This is due to the preferential deposition of intra-abdominal fat.
There is an increased population of small subcutaneous abdominal adipocytes in women with PCOS.

PCOS & BMI

Higher BMI is associated with lower LH levels.
Obesity affects GnRH, leading to lower LH.
Women with very high BMI are less likely to have an elevated LH:FSH ratio.

PCOS & Insulin Resistance

Ideal insulin resistance cutoff is 25 kg/m2.
Multi-component lifestyle interventions are recommended to reduce weight and insulin resistance.
Balanced dietary approaches can help reduce dietary energy intake.

PCOS & Weight Loss

Achievable weight loss of 5% to 10% within 6 months can improve clinical outcomes.
Weight loss can improve menstrual regularity.
To achieve weight loss, a calorie deficit of 30% or 500-750 kcal/day is generally recommended.
Energy requirements should be tailored individually, considering weight and physical activity levels.

PCOS & Diet

No specific diet type is consistently better than another for women with PCOS compared to those without.
Dietary changes should be tailored to preferences, allowing for flexibility to reduce energy intake.
Avoid restrictive and nutritionally unbalanced diets.

Low GI Diet & PCOS

A Low GI diet (50% CHO, 23% protein, 27% fat) was compared to a Conventional Diet in a study with 96 women with PCOS.
Low GI showed improved menstrual regularity (95% vs. 63% on CD) and insulin sensitivity.
Women with high insulin levels had a 2-fold reduction in body fat and modest weight loss on Low GI compared to CD.

Anti-Inflammatory Diet & PCOS

A reduced-calorie anti-inflammatory diet consisting of 25% protein, 25% fat, and 50% carbohydrates was investigated in 100 overweight women with PCOS.
The diet emphasized fish, legumes, green tea, and low-fat dairy, while limiting red meat and added sugars.
This resulted in 7.2% mean weight loss, reduced cholesterol, blood pressure, fasting blood glucose, and CRP; 63% of women regained menstrual cyclicity.

Antioxidant Rich Foods & PCOS

Antioxidant-rich foods include:
- Cold water fish (2x/week)
- Nuts (daily)
- Avocados (daily)
- Whole grains (daily)
- Beans (2-3x/week)
- Legumes (2-3x/week)
- Fruits (2-3 per day)
- Vegetables (2-5 per day)
- Green tea (daily)

DASH Diet & PCOS

The DASH diet, rich in antioxidants, showed significant reductions in insulin, CRP levels, and waist circumference in women with PCOS.

Low-Carbohydrate Diets & PCOS

Low-carbohydrate diets (45% energy from carbohydrates) may be detrimental in people with impaired glucose regulation and should be avoided in PCOS.
No optimum carbohydrate intake is established; individuals may adopt various carbohydrate ranges based on assessment, goals, habits, and preferences.
Consuming the majority of carbohydrates at lunch or distributing them equally throughout the day is advantageous.
A high-carbohydrate breakfast should be avoided.

Higher Protein Diets & PCOS

Higher protein diets may benefit lean mass preservation, glycemic control, and cardiovascular risk factors.
The benefits may be attributed to higher protein or lower carbohydrate intake, and further research is needed.
Adding 7-15 g of dietary protein to meals and snacks may improve insulin sensitivity and reduce postprandial glucose fluctuations.

MUFA & PUFA Replacement & PCOS

Replacing carbohydrates with MUFA and/or PUFA in a reduced-energy diet may offer further health benefits in the management of PCOS.

Dietary Patterns & PCOS

Healthy dietary patterns like DASH or the Mediterranean diet are recommended for women with PCOS.
They are rich in dietary fiber, antioxidants, and anti-inflammatory nutrients, promoting satiety and offering anti-hyperlipidemic, antihypertensive, and antidiabetic properties.

Timing of Food Intake & PCOS

The timing of food intake has been shown to affect metabolism and insulin secretion.
Postprandial glycemia may be under circadian regulation, and misalignment can lead to glucose intolerance.
Eating late in the day is associated with decreased energy expenditure, decreased glucose tolerance, and other metabolic dysregulations.
People with prediabetes who eat their main meal in the evening have higher HbA1c and a higher risk of developing type 2 diabetes.

Negative Energy Balance & PCOS

Studies show that negative energy balance, regardless of macronutrient composition, results in weight loss, decreased testosterone, fasting insulin, and other metabolic improvements in women with PCOS.

Gluten-Free Diets & PCOS

Gluten-free diets can be considered for PCOS patients with gastrointestinal issues like constipation, diarrhea, gas, bloating, joint pain, and fatigue.

Dietitian Role in PCOS

Dietitians provide empathetic, supportive, and encouraging guidance.
They educate on PCOS, insulin resistance, inflammation, healthy diet, supplements, sleep, stress, and exercise.
They encourage sustainable approaches to eating and exercise rather than focusing solely on weight loss.
They assess symptom severity and medication and supplement compliance.

Iron Supplementation & PCOS

Oocytes and granulosa cells have transferrin receptors and store iron.
Women taking MVI or iron supplements had 40% less trouble conceiving.
40 to 80 mg of non-heme iron daily was effective.
Women consuming the majority of iron from heme sources had higher ovulatory infertility.

Chronic Inflammation & PCOS

Women with PCOS often experience chronic inflammation.
This contributes to insulin resistance, fatigue, and weight gain.
Anti-inflammatory foods like dark leafy greens, berries, vegetables, beans, lentils, green tea, red wine, avocado, coconut, olives, nuts, turmeric, cinnamon, and dark chocolate can help combat these symptoms.

Antioxidant Foods & PCOS

Antioxidant-rich foods improve egg quality, promote ovulation, reduce inflammation and insulin resistance, and support a healthy pregnancy.

PCOS & Lactation

PCOS can be associated with challenges in breastfeeding, including:
- Insufficient milk production
- Failure of breast tissue to develop
- Insulin resistance and high androgens
- Overabundance of milk production

Establishing Adequate Milk Supply in PCOS

Pumping after feedings for 10-15 minutes on each breast in the first two weeks is crucial.
Frequent feedings with full drainage are important.
Adequate diet and fluid intake are necessary.
Extra breast stimulation through nursing or pumping sessions is essential.
Resources should be accessed before birth.
