Diet & Lifestyle Changes That Help with PMOS

The insulin connection

Since insulin resistance is at the root of most PMOS cases, the most effective dietary strategy targets blood sugar stability. This means choosing low-glycaemic carbohydrates (brown rice, oats, legumes) over refined ones, pairing carbs with protein or fat to slow glucose absorption, and eating regular meals rather than long fasting periods followed by large ones. Even modest improvements in insulin sensitivity can restart regular ovulation.

Foods to prioritise

Anti-inflammatory foods are your allies: fatty fish, turmeric, berries, leafy greens, and olive oil all help reduce the chronic low-grade inflammation that drives PMOS symptoms. Fibre is particularly important — it feeds gut bacteria that help metabolise oestrogen and androgens. Aim for 25–30g of fibre daily from vegetables, legumes, and whole grains. Spearmint tea, consumed twice daily, has meaningful evidence for reducing testosterone levels in women with PMOS.

Movement that works

High-intensity exercise is not always the answer for PMOS. Long, hard cardio sessions can spike cortisol, which worsens insulin resistance and androgen levels. Instead, a mix of moderate cardio (brisk walking, cycling) and strength training tends to work best. Resistance training in particular improves insulin sensitivity and helps maintain muscle mass, which acts as a glucose sink. Aim for 150 minutes of moderate activity per week as a baseline.

Sleep and stress — the overlooked pillars

Chronic sleep deprivation and high stress both raise cortisol, which elevates insulin and androgens. Prioritising 7–9 hours of sleep and managing stress through whatever works for you — walking, journaling, therapy, breathing exercises — is not optional when treating PMOS. Many women see significant cycle improvements simply by addressing sleep and stress, without any dietary changes.
