Metabolism and Menopause: What Changes and What Helps

Metabolism does slow through midlife, but menopause is only part of the reason. Current expert guidance says ageing, with its loss of muscle and daily movement, drives most of the weight gain. Falling oestrogen mainly changes where fat is stored, moving it towards the abdomen. That is good news, because muscle, activity, sleep and food are all things you can act on. Below we explain what changes, why, and how to eat and train to support your metabolism. Our ancient grain flours, protein powders and nut butters sit in the food part of that plan.

TL;DR

  • Midlife weight gain is driven mainly by ageing-related loss of lean mass and activity. Menopause has a clearer effect on where fat is stored, especially around the waist.
  • Poor sleep, common in perimenopause, can raise appetite and affect blood sugar control.
  • There is no single best menopause diet. A plant-forward, fibre-rich pattern with enough protein is the consistent recommendation.
  • Full-body strength training twice a week or more, plus 150 to 300 minutes of aerobic activity, is the most effective way to protect muscle.
  • Waist size, blood pressure, glucose and cholesterol are worth checking with your GP or a menopause clinician.

What metabolism is and what actually changes at menopause

Metabolism is the rate at which your body uses energy: keeping you alive at rest, digesting food and powering movement. Most of it is the resting part, and muscle is a large contributor, because lean tissue uses more energy than fat tissue.

That is why the usual story, “oestrogen drops and your metabolism crashes”, is too simple. The International Menopause Society’s recommendations say that the age-related decline in lean body mass and physical activity lowers total energy expenditure and contributes to midlife weight gain. The same document puts the menopause-specific effect mainly on body-fat distribution, with fat shifting towards the abdomen.

So two things happen at once:

  1. Ageing reduces muscle and movement, so you burn fewer calories than you did at 35.
  2. Falling oestrogen changes where fat goes, favouring the middle of the body.

You can notice the second without the first showing on the scales. A 2021 review notes that menopause can bring more fat mass and less fat-free mass with little change in scale weight, so your waistband can tell you more than the bathroom scale.

Why belly fat becomes more likely

The fat that builds up around the organs is called visceral fat. A 2025 review in Nature Reviews Endocrinology reports that menopausal women are more likely to gain excess adipose tissue deposited preferentially in the viscera, largely driven by declining oestrogen. The authors argue that oestrogen helps fat cells stay sensitive to insulin and keeps inflammation in balance, so losing that signal may contribute to visceral fat expansion.

A longitudinal study from 2008 followed women through the transition. Those who became postmenopausal gained total body fat and visceral fat, and had lower energy expenditure. Their fat oxidation fell by 32%. Physical activity had already started to drop about two years before menopause and stayed low.

That last detail matters. Part of the metabolic change follows a drop in activity, and activity is the part you control. Fatigue, joint aches, hot flushes and poor sleep all make exercise harder at exactly this stage, so planning for movement early helps.

Sleep, appetite and blood sugar

Sleep problems become more common across the transition. A review of SWAN-related evidence reported disturbed sleep in 16 to 42% of women before menopause, 39 to 47% in perimenopause and 35 to 60% after menopause.

Sleep disruption ranges across menopause stages

This is a metabolic issue as well as a comfort one. A 2025 lifestyle-medicine review explains that sleep disruption can raise energy intake through appetite hormones: leptin falls and ghrelin rises. Disturbed sleep is also linked mechanistically to insulin resistance and impaired glucose tolerance. If you wake after a poor night craving biscuits, that is biology, not weakness. We cover the cravings side in more detail in our guide to perimenopause sugar cravings.

The same review lists the sleep habits with the best support:

  • a consistent sleep and wake time
  • a cool, dark, quiet bedroom
  • fewer screens and stimulating activities before bed
  • regular daytime activity
  • less caffeine, alcohol, large meals and evening fluids late in the day

The bed itself counts too. Guides on how lack of sleep affects health show how broad the effects of short sleep are, which is a good reason to protect it. Our drinks for menopause guide covers what to sip and what to limit in the evening.

Insulin, cholesterol and metabolic syndrome

Metabolic health is more than weight. A 2022 review describes menopause as associated with abdominal adiposity, altered lipids and insulin resistance. Metabolic syndrome combines abdominal obesity, abnormal blood fats, raised blood glucose or insulin resistance, and high blood pressure. The same review summarises SWAN data showing that its incidence rose gradually from six years before to six years after the final period.

Another review found that in postmenopausal women without obesity, more abdominal fat was linked to lower insulin sensitivity and glucose tolerance. In plain terms, a normal BMI does not guarantee that your metabolic health has stayed the same.

This is the point to involve a professional. If your waist is growing, or you have a family history of diabetes or heart disease, ask your GP or a menopause clinician to check blood pressure, glucose and cholesterol. The lifestyle-medicine review recommends monitoring these alongside waist size, and treating menopause symptoms that disrupt sleep or movement.

How to eat for a steadier metabolism

The evidence does not back one special menopause diet. A 2021 review concluded that no single weight-loss diet is superior, and that any approach must be safe, nutritionally adequate, affordable, culturally acceptable and maintainable. What the guidance does agree on is the shape of a good pattern: the 2025 lifestyle-medicine review favours a plant-rich, fibre-rich, Mediterranean-like diet with unsaturated fats and appropriate protein, and fewer energy-dense, processed foods. The European Menopause and Andropause Society (EMAS) likewise advises fibre-rich meals and mainly mono- and polyunsaturated fats.

Here is how that looks on a plate.

Protein at every meal

Protecting muscle means giving it the material to work with, alongside training. Protein is the most direct dietary lever, and it also helps meals feel more filling. Our article on why protein matters in menopause goes through amounts in detail.

In practice, a protein powder is the simplest way to reach a good breakfast or post-workout serving. We stock vegan protein powders and whey and casein protein powders, so you can choose by preference. If you like a chocolate flavour, there is an organic whey protein powder in chocolate, and a vanilla version. For a quick meal replacement, there is the organic slim protein mealshake in chocolate.

Whole grains instead of refined ones

A fibre-rich pattern starts with the base of your meals. Our ancient grain flours are minimally processed, which suits baking, porridge and pancakes. If you avoid gluten, the gluten-free flours cover the same uses. Our guide to ancient grains in menopause explains how to bring them into everyday cooking.

Nuts, seeds and unsaturated fats

The guidance favours unsaturated fats, and nuts and seeds are an easy source. A spoonful of nut butter on porridge or toast adds fat and flavour, and slows a breakfast down. Options include organic raw pecan butter and organic raw pistachio butter.

A simple day of eating

This is an example, not a prescription:

Meal Example What it does
Breakfast Porridge made with ancient grain flakes, a scoop of protein powder, nut butter and berries Protein and fibre to start the day
Lunch Vegetable and bean soup with wholegrain bread Fibre-rich plant foods
Snack Yoghurt with seeds, or a menopause smoothie Steady energy, protein top-up
Dinner Fish or tofu, vegetables, a wholegrain side, olive oil Unsaturated fats, protein

EMAS suggests taking protein mainly from fish, poultry and skimmed dairy, and eating red and processed meat less often.

Strength training and activity: the biggest lever

If muscle loss is the main driver of the slowdown, resistance training is the most direct answer. The lifestyle-medicine review recommends 150 to 300 minutes a week of moderate-to-vigorous aerobic activity, plus full-body strengthening on at least two days, with balance work as you get older.

There is trial evidence for the strength part. In a randomised 15-week study of postmenopausal women, whole-body resistance training three days a week reduced abdominal fat, visceral fat and total abdominal fat compared with controls, among women who completed the programme. A review of body composition across the transition adds that diet and either aerobic or resistance exercise can reduce weight and visceral fat, but resistance training is particularly valuable for countering lean mass loss.

To get started:

  1. Pick three to five whole-body moves: squats or sit-to-stands, a push, a pull, a hip hinge and a carry.
  2. Begin with two sessions a week, then build towards three as it becomes routine.
  3. Add load slowly so the last few repetitions feel hard but controlled.
  4. Walk daily, to build up your weekly aerobic minutes.
  5. Eat protein after training, for example a shake made with one of our powders.

Strength work also loads the skeleton, which matters because bone changes at the same time. Read more about bone loss in menopause and what to do about it.

If you have joint problems, heart disease or have been inactive for a long time, speak to your GP before starting a new programme.

Can you reset your metabolism?

No single intervention resets it. Intermittent fasting is a popular suggestion. A 2021 review found it may have metabolic benefits, but judged the evidence for weight loss inconclusive. The approach with the strongest backing is dull but effective: keep muscle, move daily, protect sleep and eat a plant-forward pattern you can keep up for years.

That also changes what “progress” looks like. Waist measurement, strength, energy and blood results move more reliably than the scales do.

Where our range fits

We sell the foods this guidance leans on: ancient grain flours, gluten-free flours, vegan and whey protein powders, plant-based meal shakes, nuts and seeds, nut butters, organic chocolate and honey. Start with the vegan protein powders if you want an easy protein top-up at breakfast, or browse all flours and flakes for the base of your meals.

Our view on metabolism and menopause

We think the most useful message about metabolism in midlife is that it is a muscle and habit story before it is a hormone story.

The research agrees. Ageing takes lean mass and activity, menopause moves fat towards the waist, and sleep and food either soften or sharpen both effects. None of that needs a shortcut. It needs a base of foods that do their job without fuss.

That is why we focus on ancient grains, nuts, seeds and clean plant proteins. Each flour, protein and nut butter we choose is meant to be a simple, nutrient-dense foundation. A porridge made with ancient grains, a scoop of protein and a spoonful of nut butter is a breakfast we would happily eat every day.

Pair it with strength training and good sleep, and you have a routine that works with your body.

FAQ

Does menopause slow your metabolism?

Indirectly, and mostly through ageing. The International Menopause Society says lean mass and activity decline with age, which lowers energy expenditure. Menopause itself has a clearer effect on where fat is stored, with more going to the abdomen.

How can I improve my metabolism during menopause?

Build and keep muscle with full-body strength training on at least two days a week. Add 150 to 300 minutes of aerobic activity, eat a fibre-rich, plant-forward diet with enough protein, and protect your sleep. Ask your GP to check blood pressure, glucose and cholesterol.

Why do I gain belly fat even when my weight is steady?

Because body composition can change without the scales moving. Fat mass can rise while fat-free mass falls, and falling oestrogen favours fat deposits around the organs. Tracking your waist measurement gives a clearer picture than weight alone.

Does poor sleep affect metabolism in menopause?

Yes. Disturbed sleep can raise appetite through changes in leptin and ghrelin, and is linked to insulin resistance and impaired glucose tolerance. If night sweats or insomnia are disrupting your sleep, speak to your GP or a menopause specialist about treating them.
