PCOS nutrition — fibre, protein, and no shame
For PCOS, eating more fibre and protein with lower-glycaemic choices supports insulin sensitivity and steadier energy. Fawna uses a gentle approach — modestly higher fibre and protein — without weight-loss promises or restrictive rules. (PCOS is being renamed PMOS from 2026.)
What changes for you
- Emphasis on fibre (~35 g/day) to steady blood sugar.
- Higher protein to support satiety and lean mass.
- Lower-GI carbohydrate choices rather than cutting carbs entirely.
- A gentle, sustainable approach — not a punishing deficit.
Key nutrients
| Nutrient | Daily target | Why it matters |
|---|---|---|
| Fibre | ~35 g/day | The most consistent lever for blood-sugar stability in PCOS. |
| Protein | Every meal | Supports satiety and muscle; pairs well with lower-GI carbs. |
| Lower-GI carbs | Most choices | Whole grains, legumes and fruit over refined carbohydrate. |
Common questions
What is the best diet for PCOS?
Evidence points to higher fibre and protein with lower-GI carbohydrates to support insulin sensitivity — not extreme restriction. Fawna builds this in gently.
Is PCOS being renamed?
Yes — a 2026 initiative is renaming PCOS to PMOS. Fawna covers both terms so you find what you need.
Will Fawna make me lose weight for PCOS?
No. Fawna supports insulin sensitivity through food quality and makes no weight-loss promises.
