Eating for Energy - Simple Tweaks That Make a Real Difference

If you are eating reasonably well but still exhausted, foggy, bloated, or running on empty — this article is for you. Many women I see in clinic are doing a lot right, but missing a few key pieces that would make a significant difference to how they feel day to day.

This is not about a perfect diet. It is about practical, sustainable tweaks that work with your real life — whether you are 35 or 65, managing a household, running a business, or quietly burning out behind a very full schedule.

Focus on Wholefoods — the Foundation of Everything

If there is one principle every approach to eating shares, it is this: wholefoods support health, and processed foods undermine it. Refined, additive-packed foods deplete the body of the very nutrients it needs to function — while wholefoods, as close to their natural state as possible, nourish at a cellular level.

Wholefoods include:

•      Fruit and vegetables

•      Nuts and seeds

•      Herbs and spices

•      Grass-fed meat and free-range poultry and eggs

•      Sustainably sourced fish and shellfish

•      Whole grains, legumes and beans (prepared well — more on this below)

For women dealing with fatigue and burnout, this is where to start. Every processed food you swap for a wholefood is a step toward more energy, clearer thinking, and a more stable mood.

Stabilise Your Blood Sugar — This One Changes Everything

Blood sugar instability is one of the most overlooked drivers of exhaustion, brain fog, irritability, and poor sleep — and it is extraordinarily common in women who are stressed or burned out.

When blood sugar spikes and crashes throughout the day, your body is under constant physiological stress. You get the familiar pattern: a burst of energy after eating, followed by a crash, followed by cravings for something sweet or caffeinated to pick you back up. Over time, this cycle is exhausting for your adrenal glands, your nervous system, and your brain.

The good news is that blood sugar is highly responsive to what you eat — and a few simple shifts make a profound difference:

Protein at every meal and snack

Protein slows glucose absorption, keeping blood sugar stable for longer. Aim for a palm-sized portion at every meal — eggs, fish, chicken, legumes, nuts, or quality protein powder if needed.

Never eat carbohydrates alone

A piece of fruit on its own, crackers on their own, or toast on its own will spike blood sugar quickly. Always pair carbohydrates with protein or healthy fat.

Do not skip breakfast

For women with adrenal fatigue or burnout, skipping breakfast sends a stress signal to the body first thing in the morning — raising cortisol further. A protein-rich breakfast within an hour of waking is one of the simplest, most effective things you can do.

Watch the caffeine

Caffeine raises cortisol and can destabilise blood sugar, particularly on an empty stomach. If coffee is your breakfast, this is worth addressing. Try having it after food rather than before.

Protein — Especially Important After 50

Most women undereat protein, and this tends to worsen after menopause when the body's ability to synthesise muscle protein naturally declines. This matters for far more than muscle mass.

Protein is the raw material your body uses to produce neurotransmitters — including serotonin, dopamine, and GABA — the very brain chemicals that burnout depletes. Low

protein intake contributes directly to low mood, poor motivation, anxiety, and difficulty sleeping.

Practical daily targets: aim for roughly 1.2 to 1.6 grams of protein per kilogram of body weight. For a 65kg woman, that is around 80 to 100 grams per day — significantly more than most women consume. Easy high-protein whole foods include:

•      Eggs (6g per egg)

•      Canned salmon or sardines (quick, affordable, excellent)

•      Chicken thighs — more nutrient-dense than breast

•      Greek yoghurt (unsweetened)

•      Lentils and chickpeas

•      Pumpkin seeds and hemp seeds

Add More Plants — for Every Diet

Almost everyone benefits from more vegetables. They provide essential vitamins, minerals, antioxidants, and fibre — all critical for energy, hormone balance, healthy mood, and gut function. But the best part is that there are vegetables to suit every dietary approach:

On a ketogenic or low carb diet — focus on leafy greens and cruciferous vegetables like broccoli, cauliflower, and Brussels sprouts. Aim for three heaped handfuls of greens daily and keep root vegetables to a minimum.

Paleo, plant-based, or Mediterranean — the full rainbow is available. Variety is the goal — different colours provide different antioxidants, so a wider range means broader nutritional coverage.

Eat for Your Adrenals

Burnout is fundamentally an adrenal issue. The adrenal glands — small organs that sit above the kidneys — are responsible for producing cortisol, adrenaline, and a range of other hormones that regulate energy, stress response, sleep, and immune function. When they are chronically overworked, everything suffers.

Certain foods actively support adrenal recovery, and certain ones actively undermine it.

What helps:

•      Salt cravings in burnout are real and meaningful — the adrenals regulate sodium balance, and when they are depleted, the body craves salt. A small amount of good quality salt (himalayan or sea salt) added to food or water is genuinely supportive.

•      B vitamin-rich foods — eggs, leafy greens, legumes, sunflower seeds, and fish all provide B5 and B6, the vitamins most directly involved in adrenal function.

•      Vitamin C-rich foods — the adrenal glands have the highest concentration of vitamin C of any organ in the body. Kiwifruit, red capsicum, parsley, and broccoli are all excellent sources.

•      Regular, consistent meals — skipping meals or eating erratically forces the adrenals to compensate by releasing cortisol to maintain blood sugar. Consistency is medicine for burned-out adrenals.

What undermines recovery:

•      Sugar and refined carbohydrates — drive the blood sugar rollercoaster that exhausts the adrenals further

•      Excess caffeine — particularly before food, or after midday

•      Alcohol — disrupts cortisol rhythms and sleep architecture, both critical for adrenal recovery

The Gut-Brain Connection — More Important Than You Think

Around 90% of the body's serotonin — the neurotransmitter most associated with mood, calm, and wellbeing — is produced in the gut, not the brain. This means that gut health is directly and profoundly connected to mental and emotional health.

Chronic stress damages the gut lining, disrupts the microbiome, and drives inflammation — which then worsens mood, anxiety, fatigue, and brain fog. Many women in burnout have significant digestive symptoms: bloating, irregular bowels, reflux, food sensitivities. These are not separate from the burnout — they are part of the same picture.

Foods that actively support the gut-brain axis:

•      Fermented foods — yoghurt, kefir, sauerkraut, kimchi, miso. Aim for a small serve daily.

•      Bone broth — rich in collagen and glycine, which support the gut lining directly.

•      Prebiotic foods — garlic, onion, leek, asparagus, oats, and green banana feed beneficial bacteria.

•      Bitter foods — rocket, radicchio, dandelion leaf, and apple cider vinegar stimulate digestive enzymes and bile flow.

Practical Eating When You Have No Energy

This is the section I know many of you need most. The gap between knowing what to eat and actually doing it when you are exhausted is real — and rarely addressed.

Here is what I suggest to clients who are in the depths of fatigue:

Keep it simple and repeatable

You do not need a different meal every night. Having three or four nourishing meals you can make without thinking — and rotating them — reduces decision fatigue and makes consistency possible.

Batch cook one day a week

One hour on a Sunday — a pot of soup, a tray of roasted vegetables, some boiled eggs, a batch of lentils — means you have nourishing food available without effort for several days. This is not meal prep perfection. It is just having something good already done.

Stock a burnout emergency shelf

Canned fish, canned legumes, eggs, frozen vegetables, nuts, good quality crackers, tinned tomatoes, and coconut milk. With these on hand you can make a nourishing meal in ten minutes on the worst days.

Eat foods you actually like

Research has shown that people absorb fewer nutrients from foods they dislike or are unfamiliar with. If you are forcing down food you hate in the name of health, stop. Find nourishing foods you genuinely enjoy and build from there.

How You Prepare Your Food Matters

Many traditional cultures developed elaborate food preparation methods for good reason — preparation genuinely affects both flavour and nutrient availability.

•      Marinate meat before cooking to improve digestibility and reduce harmful compounds formed at high heat.

•      Soak and rinse beans and legumes overnight to reduce phytic acid, which blocks mineral absorption.

•      Activate nuts and seeds by soaking overnight and drying — this neutralises enzyme inhibitors and improves digestibility.

•      Cook tomatoes to increase lycopene availability — one of the rare cases where cooking increases nutrient value.

•      Add fat to your salads — fat-soluble vitamins (A, D, E, K) in vegetables require dietary fat to be absorbed. Olive oil dressing is not just flavour.

Eat Mindfully — How You Eat Is as Important as What You Eat

If you are shovelling food down at your desk, in the car, or while scrolling your phone — you are not getting the full benefit of even the most nourishing meal. Digestion begins in the brain, with the anticipation of food. When we eat hurriedly and distractedly, we produce fewer digestive enzymes, chew less thoroughly, and absorb less nutrition.

For burned-out women in particular — eating is an opportunity to rest, not another task to rush through. Even ten minutes of sitting down, eating without a screen, and tasting your food makes a measurable difference to how your nervous system processes the meal.

Enjoy Your Treats — Without Guilt

Restriction breeds obsession. When we deny ourselves something completely, we tend to think about it constantly and then overcorrect. A sustainable approach to eating has room for occasional treats — chosen consciously and enjoyed fully. The goal is not perfection. It is a long-term relationship with food that feels nourishing rather than punishing.

If you have digestive issues such as bloating, wind, heartburn, constipation or reflux — you may benefit from a personalised plan about which foods are most supportive for your particular picture. Book a free 15 minute chat to discuss whether a consultation or specific testing would be helpful.
