INSIGHT

PCOS Is A Systemic Endocrine Condition

  • PCOS is an endocrine condition driven by excess androgens from ovaries and adrenals, not just ovarian cysts.
  • It links to insulin resistance, metabolic risks, and brain effects like mood and neurodiversity.
ADVICE

Test Fasting Insulin And Balance Meals

  • Test fasting insulin to detect insulin resistance because normal glucose can mask it.
  • Eat balanced meals with protein, vegetables, and soluble fiber to stabilize blood sugar.
ADVICE

Prioritize Protein And Strength Training

  • Aim for roughly 30 grams of protein per meal and a minimum ~90 g/day to reduce cravings and build muscle.
  • Use strength training to increase muscle mass and improve insulin sensitivity.
