Perimenopause Nutrition: A Practical Guide for Women Over 45

What's actually happening hormonally

Perimenopause is the transition into menopause, and for most women it starts in their 40s, sometimes earlier. Oestrogen and progesterone begin to fluctuate rather than following their usual steady monthly rhythm, and it's this fluctuation, not just the eventual decline, that drives so many of the symptoms women notice: disrupted sleep, mood changes, bloating, fatigue and changes in weight distribution.

Nutrition doesn't stop these hormonal shifts happening. What it can do is support your body through them, steadying blood sugar, reducing inflammation and giving your body the raw materials it needs to manage the transition with fewer, milder symptoms.

Foods that help

Protein at every meal. As oestrogen declines, women naturally lose muscle mass more easily. Aiming for a palm-sized portion of protein at each meal, eggs, fish, chicken, tofu, legumes, helps preserve muscle and keeps blood sugar steadier, which in turn helps with energy and mood.

Fibre-rich vegetables and wholegrains. Fibre supports gut health, and a healthy gut plays a bigger role in hormone regulation than most people realise (more on that below). It also helps manage the blood sugar swings that can make perimenopause symptoms feel worse.

Phytoestrogen-rich foods. Foods like flaxseed, chickpeas, lentils and edamame contain plant compounds that can gently support the body as oestrogen levels shift. They're not a replacement for medical treatment where that's needed, but they're a genuinely useful part of a balanced plate.

Healthy fats. Omega-3s from oily fish, walnuts and flaxseed support brain health and can help ease mood-related symptoms that often accompany perimenopause.

Foods that tend to make symptoms worse

Refined sugar and highly processed carbohydrates can worsen blood sugar swings, which often shows up as energy crashes and increased irritability. Alcohol and caffeine, particularly later in the day, are common triggers for disrupted sleep and night sweats. None of this means cutting these things out entirely, it's about noticing your own patterns and adjusting what doesn't serve you.

Why this is hard to do alone

Most women reach perimenopause with decades of dieting advice in their head that simply doesn't apply anymore. What worked in your 20s and 30s often stops working, and generic advice rarely accounts for what's happening with your individual hormones and gut health.

This is exactly what the Eat Better Feel Better membership is built around. Rather than generic nutrition advice, members get a structured approach across nutrition, gut health, hormones, sleep and movement, built specifically for this stage of life, plus the option of blood, genetic and gut testing if you want a clearer picture of what's happening in your own body.

If you're ready for a more personalised approach, you can start with a 30-day free trial and see how the programme fits into your life.
