You're eating clean, training hard, tracking every macro. And the scale won't move. It's not your discipline, it's your biology.

Tanvi unpacks the 1989 research on intrinsic metabolic slowdown and the up-to-400-calorie daily gap working against women with PCOS. She breaks down the Monash University study that pumped insulin into 71 women to settle the insulin-resistance question once and for all, plus the four markers to track when your bloodwork reads "normal."

In this episode:

• Why "eat less, move more" quietly fails women with PCOS and insulin resistance
• The 1989 research showing PCOS causes intrinsic metabolic slowdown, and how women with PCOS can burn up to 400 fewer calories a day
• How chronic low-grade inflammation can block fat loss even in lean bodies
• The leptin-ghrelin breakdown behind food noise and hunger after a full meal
• What the Monash University study settled by pumping insulin into 71 women: does PCOS actually drive insulin resistance?
• Why an HbA1c of 5.8 gets called "normal" while insulin resistance is already building
• The four markers to track instead of HbA1c alone: triglyceride-to-HDL ratio, fasting insulin, waist-to-hip ratio, and testosterone
• How cortisol creep from too much cardio can worsen PCOS by triggering androgens and more insulin resistance
• Why 16 weeks of strength training lowered testosterone and fixed fasting glucose, and how muscle acts as a carb sink
