Eating for Steady Energy in Peri-menopause

Simple, food-first swaps that keep blood sugar and mood on an even keel through the day.

You know that feeling when it's 3pm and you're absolutely certain you need a biscuit or you might actually cease to function? Or when you wake up feeling okay but by mid-morning you're snappy, foggy, and running on empty? If this sounds familiar, and you're somewhere in the peri-menopause years, those energy crashes are probably not just about being tired or busy. A lot of the time, what's happening is a blood sugar rollercoaster, and during peri-menopause, the ride gets a whole lot bumpier.

Here's the good news: you don't need a complicated diet overhaul to feel better. Some genuinely simple food swaps can make a real difference to how you feel across the day. Let's get into it.

Why Blood Sugar and Steady Energy in Peri-menopause gets Tricky

Before we talk food, it helps to understand what's actually going on in your body.

As oestrogen levels start to fluctuate and decline during peri-menopause, your cells become less sensitive to insulin, the hormone that helps move glucose from your bloodstream into your cells for energy [1]. This means the same foods that felt totally fine in your thirties can now send your blood sugar spiking and crashing in ways they didn't before and why steady energy in peri-menopause gets trickier.

When blood sugar spikes, your body pumps out insulin to bring it back down. If it overshoots, blood sugar drops too low, and that's when you get that jittery, irritable, brain-foggy, "I need sugar NOW" feeling. Over time, these repeated spikes and crashes can contribute to weight gain (particularly around the middle), poor sleep, increased anxiety, and worsening hot flushes [2].

Research published in Menopause found that perimenopausal women had significantly greater blood sugar variability compared to pre-menopausal women, even after eating the same meals [3]. So yes, it's not your imagination. Your metabolism genuinely has changed.

The beautiful thing, though, is that food is one of the most powerful levers you have. And we're not talking about going low-carb forever or eating like a rabbit. We're talking about small, strategic swaps that work with your hormones rather than against them.

Swap 1: Ditch the Toast-Only Breakfast

A bowl of cereal, a couple of slices of toast with Marmite, or a muffin on the run, these are classic New Zealand breakfasts, and they're also classic blood sugar bombs. Refined carbohydrates on their own digest quickly, sending glucose into your bloodstream fast, which triggers that big insulin response and sets you up for a crash by mid-morning [4].

The swap: Build your breakfast around protein and healthy fats, with some fibre-rich carbohydrate alongside.

Think eggs with sourdough and avocado, Greek yoghurt with berries and a handful of seeds, or even leftovers from dinner if that works for you. Protein slows gastric emptying, which means glucose enters your bloodstream more gradually and your blood sugar stays far steadier [5].

A study in The American Journal of Clinical Nutrition found that a high-protein breakfast significantly reduced post-meal blood sugar spikes and reduced cravings later in the day compared to a high-carbohydrate breakfast [6]. That mid-morning snack attack? It starts at breakfast.

Quick practical idea: Keep a bag of pumpkin seeds and some Greek yoghurt in the fridge. It takes two minutes and it's genuinely enough to hold you through a busy morning.

Swap 2: Stop Eating Carbs Alone

This is one of the simplest and most effective changes you can make. Carbohydrates on their own, a handful of crackers, a piece of fruit, a rice cake, spike blood sugar faster than the same food eaten alongside protein, fat, or fibre [7].

The swap: Never let carbohydrates eat alone. Always pair them with a friend.

Crackers with hummus or nut butter. An apple with a small handful of almonds. Rice or pasta alongside plenty of vegetables and a protein source. Even just adding a drizzle of olive oil to your vegetables makes a difference because fat slows the absorption of glucose [8].

This isn't about avoiding carbohydrates; they're important for serotonin production, thyroid function, and energy. It's about having them in a way that your body can actually use, rather than sending you on a sugar spiral.

Swap 3: Eat Vegetables & Protein Before (or With) Your Carbs

This one sounds almost too simple to be real, but the research is genuinely impressive. When you eat fibre-rich vegetables and protein before or alongside your carbohydrates, you can significantly reduce the blood sugar rise after that meal.

A study published in Diabetes Care showed that eating vegetables and protein before carbohydrates at the same meal reduced post-meal glucose by up to 36% compared to eating the carbohydrates first [9]. That's a remarkable difference from simply changing the order (or proportion) of what's on your plate.

The swap: Start your meals with a salad, some greens, or non-starchy vegetables before you get to the rice, bread, or pasta.

In practice this might look like: a small side salad with a sprinkle of nuts or seeds while you're dishing up dinner. Some cucumber and carrot sticks with hummus or tzatziki while you wait for your pasta to cook. A bowl of chicken and vegetable soup before your sandwich at lunch. Small tweaks, genuinely meaningful results.

Swap 4: Rethink Your Afternoon Snack

The 3pm slump is real, and during peri-menopause it can be particularly brutal. If you're reaching for something sweet at this time of day, that's usually your blood sugar crashing and your brain screaming for a quick hit of glucose.

The problem is that sugary snacks, even "healthy" ones like muesli bars, dried fruit, or flavoured yoghurts, will give you that hit and then drop you harder on the other side. You'll feel better for twenty minutes and then worse than before [10].

The swap: Choose a snack with at least two of these three: protein, fat, fibre.

Some great options that you can easily find in New Zealand: a small handful of mixed nuts, a boiled egg with some cherry tomatoes, natural peanut or nut butter on a couple of oatcakes, cheese with apple slices, or some edamame with a pinch of sea salt.

These snacks give you sustained energy because they don't spike your blood sugar in the first place. The fibre and protein also help feed your gut microbiome, which, interestingly, is increasingly linked to oestrogen metabolism and mood regulation during menopause [11].

Swap 5: Don't Skip Meals (Even When You're Busy)

This one is for every woman who drinks coffee until midday and calls it breakfast. Skipping meals, particularly in the morning, can lead to elevated cortisol (your stress hormone), and during peri-menopause when cortisol is already prone to running higher, this creates a compounding effect on both blood sugar and mood [12].

When cortisol is high, your body releases stored glucose into your bloodstream even without you eating anything, which primes you for the exact blood sugar rollercoaster we're trying to avoid.

The swap: Eat something within an hour or two of waking, even if it's small.

It doesn't have to be a big production. A small pot of Greek yoghurt, a handful of nuts and a piece of fruit, or even some leftover dinner. The goal is simply to signal to your body that fuel is available, which helps dial down cortisol and stabilise blood sugar for the rest of the day [13].

Swap 6: Swap Your Evening Sweet Treat for Something That Works Harder

Evening is often when the sweet cravings hit hardest, and that's partly because serotonin (your feel-good neurotransmitter) naturally dips in the evening, making you reach for sugar to get a temporary boost [14]. The trouble is that a sugary snack in the evening can disrupt your sleep by causing a blood sugar spike right when your body is trying to wind down.

The swap: Try a small piece of good quality dark chocolate (70% cocoa or higher) with a few walnuts, or a small bowl of full-fat Greek yoghurt with a little honey and some flaxseeds.

Dark chocolate contains magnesium, which many perimenopausal women are deficient in and which supports sleep quality and mood [15]. Walnuts are rich in omega-3 fatty acids, which support brain health and have been shown to reduce inflammation, a growing concern during menopause [16]. And full-fat dairy provides tryptophan, the precursor to serotonin, so you're actually giving your brain what it was looking for in a much more sustainable way.

A Word About Mood

It's worth pausing here to acknowledge that for many women in peri-menopause, the mood piece is the hardest part. The irritability, the anxiety, the sudden tearfulness, it can feel like you've lost control of your own emotional thermostat.

Blood sugar instability is a significant, and often underappreciated, driver of mood changes during peri-menopause. When blood glucose drops rapidly, your body releases adrenaline as part of the stress response, which can trigger feelings of anxiety, panic, and irritability [17]. Over time, repeated blood sugar crashes can also blunt your brain's sensitivity to serotonin and dopamine, making you more vulnerable to low mood [18].

The good news is that stabilising your blood sugar through consistent, nourishing meals is genuinely one of the most effective things you can do for your mood, not just your energy levels. It's not a magic fix, and if you're struggling significantly please do reach out to your GP or a counsellor, but it is a real and meaningful piece of the puzzle.

Putting It All Together

You don't need to do all of this at once. In fact, please don't try to overhaul everything overnight because that's a recipe for overwhelm and giving up. Instead, pick one swap that feels manageable and try it for a week. See how you feel. Then add another.

Here's a simple example of what a steadier-energy day might look like:

Breakfast: Scrambled eggs with spinach on sourdough toast, with half an avocado.

Morning snack (if needed): A small handful of almonds and a piece of fruit.

Lunch: A big salad with some tinned salmon or chickpeas, olive oil dressing, and a slice of wholegrain bread.

Afternoon snack: A small pot of Greek yoghurt with pumpkin seeds, or some cheese and oatcakes.

Dinner: A palm-sized portion of protein (chicken, fish, tofu, legumes), loads of non-starchy vegetables, and a smaller portion of carbohydrates like kumara, rice, or quinoa.

Evening: A couple of squares of dark chocolate and a few walnuts, or a herbal tea with a small pot of Greek yoghurt.

The Bottom Line

Peri-menopause asks a lot of you. Your body is changing in ways that can feel confusing and frustrating, and the last thing you need is to feel like you're constantly running on empty or riding an emotional wave you didn't sign up for.

The simple truth is that what you eat, and how you eat it, has a powerful influence on how you feel day to day. Stabilising your blood sugar doesn't require perfection or deprivation. It requires a bit of awareness, some simple strategic pairing, and a commitment to feeding yourself well consistently.
