If you tapped through that day nodding, you are far from the only one. Women sit down in my clinic every week and describe it in almost the same words: tired all the time, snappy by teatime, reading the same email three times, awake at 3am for no reason you can name. Different lives, strangely similar days.
There is a reason those days look so alike. For years, your hormones have acted like a quiet metabolic shield: keeping blood sugar steady, fat in safer places and inflammation low, without you having to think about any of it. Through perimenopause that shield thins, and the body starts handling fuel and stress differently.
What surfaces is the state of your metabolic health underneath, which for many women has been quietly under strain for decades. That is why the symptoms of perimenopause overlap so closely with the symptoms of unsteady metabolic health: brain fog, fatigue, weight settling around the middle, anxiety, broken sleep. The overlap is the clue, and it is where the hope lies, because metabolic health can be steadied at any age.
The shape of the day matters too, because each symptom feeds the next. A rushed or skipped breakfast sets up a mid-morning dip in blood sugar. The dip gets patched with coffee and something sweet, so the crash lands mid-afternoon instead. A late, heavy dinner keeps blood sugar and body temperature raised into the night. Somewhere around 3am, your body corrects a falling glucose level with a burst of adrenaline, and you are suddenly wide awake, heart thumping. The broken night raises hunger hormones the next morning, and the whole loop starts again, a little deeper.
A body under strain will always find a way to tell you. The question worth asking is why now, and what is driving it.
Here is what I want you to take from this page: that loop responds to change, and often sooner than you might expect. Blood sugar steadies within days of eating differently, and sleep tends to follow once evenings change shape. Clearer thinking takes longer, weeks rather than days, but it builds. For many of the women I work with, the biggest early shift is hope: the discovery that a pattern which took years to build can start to loosen within a month.
Rebalancing your metabolic health supports you through menopause whether you decide to use HRT or not, and it runs alongside whatever you and your GP decide.
The Metabolic Quartet
When we look underneath the symptoms, the same four areas tend to slip together. I call them the Metabolic Quartet, and every root cause appointment assesses all four:
Tap a driver to see what it does, and which of the others it pulls on.
Blood sugar: your body holds it less steady than it used to, so meals that never caused a problem before can now bring energy crashes, cravings, fog and weight settling around the middle.
Feeds visceral fat: glucose the body cannot use well gets stored as fat around the organs.
Visceral fat: fat stored around the organs shifts and grows, fuelling inflammation, aches and low mood.
Pulls on muscle: the inflammation it produces speeds up muscle loss.
Muscle: quietly declining from the mid-forties, and it is where the body burns fuel and stores carbohydrate safely.
Pulls on blood sugar: with less muscle, glucose has fewer safe places to go.
Chronic stress activation: a stress response stuck on, with cortisol that clears more slowly. You feel tired but wired, and sleep turns light.
Pulls on blood sugar: cortisol raises it and keeps it swinging.
The link runs deeper than it might seem. In the SWAN study, which followed a large group of women for over a decade, insulin levels in the late forties were linked to when hot flushes began and how long they lasted, even when body weight and blood glucose were not. An observational finding, so it shows association rather than proof, but it points to how closely metabolic health and the menopause experience are tied.

The patterns women bring to clinic
The day above shows one woman. These symptoms surface differently in every woman, shaped by your gut health, your medical history, your nutrition status and the life you live. Your version will be your own, and you might recognise one of the patterns below, or several at once.
Energy you can't rely on
Nutrition · Sleep
Tired all the time, waking unrefreshed, hitting a wall mid-afternoon however early the night ended. Energy like this is usually a blood sugar story as much as a sleep story: glucose peaks and dips force the body through cycles of surge and crash, while broken nights interrupt the repair work that should reset everything overnight. Steadier meals and steadier evenings rebuild it from both ends.
Brain fog and the words that go missing
Mindset · Nutrition
Reading the same page twice. Losing a word mid-sentence in a meeting you are supposed to be leading. The brain runs on a steady fuel supply, and when blood sugar swings through the day, focus and recall usually slip first. For most women this fog is temporary, and it lifts as the fuel supply steadies.
Weight that stopped responding
Nutrition · Movement
Eating the same, moving the same, gaining anyway, usually around the middle. Through perimenopause the body responds to insulin differently and stores fat in new places, while muscle, the tissue that keeps metabolic rate up, declines faster than before. I have written about these mechanisms in detail in Why you're gaining weight in perimenopause.
Headaches, migraines and new aches
Movement · Nutrition
Headaches arriving in new patterns. Migraines appearing for the first time, or worsening after years of being manageable. Joints that ache without an injury to blame. Pain often changes character through perimenopause: hormone fluctuations affect pain sensitivity and blood vessels, and low-grade inflammation from the metabolic side lowers the threshold further. Mapping when it strikes is frequently the first clue to what is driving it.
Results drifting in the wrong direction
Nutrition · Movement · Sleep
Blood pressure edging up at a routine check, a glucose reading in the pre-diabetes range, cholesterol shifting for the first time in your life. These midlife changes are common, and they respond well to early action, because the drivers behind them, insulin resistance, muscle loss and disturbed sleep, are the same ones this page describes. Caught early, the trajectory can genuinely change.
A gut that behaves differently
Nutrition · Mindset
Bloating that builds as the day goes on. Foods that never used to be a problem, suddenly disagreeing with you, sometimes with IBS-like symptoms after years of an easy gut. The gut responds to hormonal shifts, stress load and eating patterns all at once, so it is often where several roots surface first. It tends to settle as the underlying pattern does, and it deserves proper assessment in its own right.
The Five Roots
This is the framework behind every appointment at the Root Cause Clinic. Five areas of your life, assessed together, because they rise and fall together:
- Nutrition: what you eat and when, and how that steadies or destabilises blood sugar through the day.
- Movement: how much and what kind, since muscle is where the body burns fuel and stores carbohydrate safely, and it declines faster from the mid-forties.
- Sleep: quantity and quality, and how a run of broken nights compounds every other root.
- Mindset: stress load and nervous system regulation, a physiological input in its own right.
- Environment: the kitchen, the diary and the daily routine that make change either sustainable or exhausting.
Where to start this week
You do not need an appointment to begin. These five changes come up in my clinic more than any others, because they are small yet powerful:
- Put protein at the centre of breakfast. Eggs, Greek yoghurt, or leftovers from last night. A steadier morning makes a steadier day.
- Walk for ten minutes after your biggest meal. Working muscles draw glucose out of the blood without needing a surge of insulin.
- Ease dinner earlier and lighter where the family diary allows. Cooler, calmer nights tend to follow.
- Lift something twice a week. Muscle is where glucose is stored and burned, and protecting it protects nearly everything else.
- Keep the last hour before bed the same each night. Low light, screens away. The body clock repays routine, especially now.
Pick one or two and hold them for a fortnight. Small and steady outlasts dramatic every time.
Where the Root Cause Clinic fits
Some women make real headway with those changes alone. If you would like to understand what is driving your own pattern first, that is what a root cause appointment is for.
The clinic is designed around you. We spend 45 minutes together going through your history, your symptoms and the days you actually live. An InBody scan adds a precise measure of muscle and body fat, the things your scales can't tell you, one input read alongside everything else you bring. You leave with a health action plan personalised to you: which of the Five Roots we start with, what to change first, and how we will know it is working.
If you need more support
Your Menopause Code is the 12-week programme: four appointments, three InBody scans, a continuous glucose monitor and a personal metabolic plan built with you as you go. The first cohort sold out. The founding rate of £495 runs until 1 September 2026, and you can spread it over two instalments.
