PCOS has a new name. It's PMOS — Polyendocrine Metabolic Ovarian Syndrome. Renamed by global consensus in The Lancet, 12 May 2026, after an 11-year multistep process involving 22,000+ patients and clinicians worldwide.
Why the rename? The old name focused on one finding (cysts on the ovaries). PMOS reflects what the condition actually is: a polyendocrine and metabolic disorder where insulin resistance and hormonal imbalance drive most symptoms. Same condition, more accurate frame, less stigma.
What's the nutrition approach? Generic "eat less, move more" doesn't work for PMOS. The Teede International Guideline (JCEM 2023) confirms insulin resistance underlies most phenotypes, so generic low-fat low-calorie diets miss the real lever.
4 nutrition shifts that actually move the needle:
· Shift 1: Carb quality + timing. Lower-glycaemic, higher-fibre carbohydrates eaten alongside protein and fat.
· Shift 2: 25 to 35g protein per main meal to blunt the glucose spike and protect lean mass.
· Shift 3: Inositol (myo plus d-chiro, 40:1 blend per Fitzgerald JCEM 2024) and omega-3 (Moran Obes Rev) where appropriate. Discuss before starting.
· Shift 4: A 5 to 10% body-weight reduction helps those who need it, but the other three shifts improve insulin resistance and symptoms regardless of weight change. PMOS care is not weight loss in disguise.
