Frequently Asked Questions
Does PCOS lower your Basal Metabolic Rate (BMR)?
Clinical studies show women with insulin-resistant PCOS may have a 10–15% lower resting metabolic rate compared to non-PCOS controls of identical weight.
What is the best macro ratio for PCOS weight loss?
A lower-glycemic macro split featuring 30% Protein, 40% Healthy Fats, and 30% Complex Carbs helps stabilize blood glucose and insulin levels.
Should women with PCOS avoid drastic calorie cuts?
Yes. Severe deficits raise cortisol levels, worsening hormonal imbalances and insulin resistance. A gentle 300-calorie deficit is recommended.
