If someone told you that one dietary change could help reduce visceral fat, stabilise your energy, improve your mood, support your bones, and help your body manage oestrogen more effectively, you’d probably want to know what it was.

It’s fibre. And most women in the UK are eating roughly half of what they need.

During menopause, the gap between how much fibre most women eat and how much their body actually needs becomes more significant because fibre does far more during this transition than simply keeping digestion moving. In this post I’ll explain exactly why fibre matters so much during menopause, and give you practical, specific ways to increase your intake without overhauling your diet.

How Much Fibre Should You Actually Be Eating?

The UK recommendation is 30g of fibre per day. The average UK adult currently eats around 18g — a shortfall of 12g every day [1]. During menopause, that gap has real consequences.

Most women know fibre is ‘good for you’ in a general sense, good for digestion, good for preventing constipation. But the role fibre plays during the menopause transition goes significantly deeper than that, and once you understand it, hitting 30g a day starts to feel less like a dietary chore and more like one of the most important things you can do for your body right now.

Why Fibre Matters More During Menopause

1. Fibre and your gut microbiome – the oestrogen connection

Your gut microbiome, the community of bacteria living in your digestive tract, plays a direct role in how your body manages oestrogen. A group of gut bacteria known as the estrobolome produce an enzyme that helps reactivate oestrogen for recirculation in the body. When microbial diversity in the gut is low, more oestrogen is excreted rather than recirculated — which can worsen the low oestrogen symptoms of menopause [2].

Fibre is the primary food source for your gut bacteria. A high-fibre diet promotes greater microbial diversity, which supports a healthier estrobolome and more effective oestrogen metabolism. In short: feeding your gut bacteria well may help your body make better use of the oestrogen it does have. You can read more about the gut-menopause connection in my dedicated post on gut health and menopause here.

2. Fibre and blood sugar – the energy and craving connection

During menopause, declining oestrogen affects insulin sensitivity, meaning your body becomes less efficient at managing blood sugar. This is one of the main drivers of the afternoon energy crash, the intense sugar cravings, and the feeling of being tired but wired that many women describe during this transition.

Soluble fibre found in oats, lentils, apples, and flaxseeds. slows the absorption of glucose into the bloodstream, helping to keep blood sugar stable throughout the day. Including a good source of soluble fibre at every meal is one of the most practical and effective ways to reduce energy crashes and cravings without restriction or calorie counting.

3. Fibre and visceral fat – the body composition connection

The redistribution of fat to the abdomen during menopause, driven by declining oestrogen, is one of the changes women find most distressing. Visceral fat, the fat that accumulates around the organs rather than under the skin, is associated with increased cardiovascular risk and metabolic disruption.

Research suggests that a higher intake of dietary fibre, particularly soluble fibre, is associated with reduced visceral fat accumulation [3]. The mechanism is partly through blood sugar regulation and partly through the short-chain fatty acids produced when gut bacteria ferment fibre which have direct effects on fat metabolism and inflammation. This is one of the reasons I encourage my clients to think of fibre as an active tool for body composition rather than just a digestive aid.

4. Fibre and mood – the gut-brain connection

The link between gut health and mental health is one of the most rapidly developing areas of nutrition science. Changes to the gut microbiome have been associated with increased incidence of anxiety and depression [4] and given that low mood and anxiety are already common symptoms during menopause, supporting gut health through diet becomes even more important.

The gut produces around 90% of the body’s serotonin, the neurotransmitter most associated with mood regulation. A diverse, fibre-fed microbiome supports serotonin production. This doesn’t mean fibre is a treatment for depression or anxiety, but it does mean that neglecting gut health during a period of hormonal vulnerability is a missed opportunity.

5. Fibre and digestive symptoms – the bloating and reflux connection

Bloating is one of the most common digestive complaints during menopause, affecting around 40% of women [5]. Constipation, which worsens bloating, is also more prevalent during this transition as gut motility slows.

Increasing fibre intake gradually, and with adequate fluid helps to keep digestion moving, reduce constipation, and support the gut environment that keeps bloating manageable. If you’re already struggling with bloating, read my post on menopause bloating for more specific guidance. And if digestive symptoms are affecting your quality of life, it’s worth getting personalised support rather than guessing.

How to Hit 30g of Fibre a Day

Thirty grams sounds like a lot until you see what it looks like in a day of normal eating. Here’s a rough guide to how fibre adds up across common foods:

Approximate fibre content of common foods:

Porridge (made with oats)  (40g dry oats)  3g fibre

Wholemeal toast  (2 slices)  4g fibre

Lentils (cooked)  (80g serving)  4g fibre

Chickpeas (cooked)  (80g serving)  4g fibre

Flaxseeds  (1 tbsp)  3g fibre

Apple (with skin)  (1 medium)  3g fibre

Raspberries  (80g portion)  2g fibre

Broccoli (cooked)  (80g portion)  2g fibre

Sweet potato (with skin)  (1 medium)  4g fibre

Almonds  (30g handful)  2g fibre

A breakfast of porridge with flaxseeds and raspberries already gets you to around 8g. Add a lunch with lentils or chickpeas, a sweet potato at dinner, and a handful of almonds as a snack, and you’re at 30g without significant effort. For a more detailed breakdown of fibre-rich foods, see my post on fibre in your diet.

The key practical points:

• Increase gradually — going from 18g to 30g overnight can cause bloating and discomfort. Add a few grams more per day over one to two weeks.
• Drink plenty of fluid — fibre needs water to work properly. Aim for 6–8 glasses of fluid per day alongside increasing your intake.
• Prioritise variety — different types of fibre feed different gut bacteria. Eating a wide range of plant foods is more beneficial than eating large amounts of one source.
• Don’t fear legumes — beans, lentils, and chickpeas are among the most fibre-rich foods available and are also excellent sources of protein and phytoestrogens. If they cause bloating initially, introduce them gradually and in smaller portions.
• Add rather than swap — rather than overhauling your diet, think about where you can add fibre to what you’re already eating. Flaxseeds in yoghurt, an extra portion of vegetables in a curry, a handful of berries with breakfast.

The Best Fibre Sources for Menopause Specifically

Not all fibre sources are equal from a menopause perspective. These are the ones I’d prioritise with clients:

Flaxseeds (linseeds)

Flaxseeds are exceptional for menopause for two reasons: they’re a rich source of soluble fibre, and they’re one of the best dietary sources of lignans, a type of phytoestrogen that can have a mild oestrogen-like effect in the body and has been associated with reduced hot flush frequency [6]. One tablespoon a day added to yoghurt, porridge, or a smoothie is an easy habit to build.

Oats

Oats contain beta-glucan, a specific type of soluble fibre with strong evidence for reducing LDL cholesterol and improving blood sugar regulation [7] both relevant priorities during menopause when cardiovascular risk increases. They’re also filling, easy to prepare, and versatile.

Legumes — lentils, chickpeas, beans

Legumes offer fibre, protein, and phytoestrogens in one food making them one of the most menopause-supportive ingredients you can include in your diet. They’re also affordable and easy to add to soups, salads, curries, and stews.

A wide variety of vegetables

Different vegetables feed different gut bacteria, so variety matters more than volume. Rather than eating large amounts of one or two vegetables, aim for as many different types as possible across the week, what we sometimes call “eating the rainbow.”
