Is keto the best diet for PCOS?

Not necessarily. Keto improves PCOS markers, but so do Mediterranean and moderate-carb approaches when total calories and protein are matched. Adherence is the deciding factor — pick what you can sustain for a year.

Does inositol help with PCOS weight loss?

Yes — myo-inositol combined with d-chiro-inositol (40:1 ratio) has multiple RCTs showing improved insulin sensitivity and modest weight-loss support. Metformin remains a first-line medical option your doctor may prefer.

Why am I gaining belly fat with PCOS despite exercising?

Elevated androgens + insulin resistance drive visceral fat storage even at stable weight. The fix is dietary (lower refined carbs, more protein) combined with resistance training — cardio alone is less effective. See Chapter 11 — Hormones & Fat Storage.

Fat Loss Calculator for PCOS

PCOS affects fat loss via two primary routes: insulin resistance (in an estimated 70% of cases) and chronic low-grade inflammation. Both mean that identical calorie deficits produce slightly slower fat loss vs. matched controls — but <strong>not</strong> the "impossible" picture social media paints. Meta-analyses show PCOS patients lose fat at ~80–90% the rate of controls on isocaloric deficits, with meaningful metabolic improvements at just 5–10% body-weight loss. This calculator sets a realistic weekly rate and maps the calorie math to a timeline your PCOS-adjusted metabolism can actually hit.

Special Considerations for Women with PCOS

⚡Prioritize protein + fibre — flattens glucose and insulin spikes
