Tired of Being Tired? The 30:30:30 Method that Boosts Midlife Energy

If you’re in your 40s or 50s and feel permanently drained, you’re not imagining it. The bone-crushing tiredness that creeps in during midlife is one of the most common complaints Emma Bardwell, the UK’s leading nutritionist for midlife women, hears. Not ‘I stayed up too late last night’ tired, but the kind of fatigue that lingers no matter how early you go to bed or how much coffee you drink.

Emma says: “Hormonal shifts, poor sleep, stress, busy lives and under-fuelled diets all play a role. But there’s one big factor that’s often overlooked: what, and how, you eat day-to-day. Over the years, both in clinic and in my own life, I’ve seen a clear pattern. When women eat enough protein, enough fibre, and a wider range of plants, their energy improves. Not overnight. Not magically. But steadily and reliably. This observation has became the backbone of my incredibly successful 30:30:30 approach.”

What is the 30:30:30 method?

At its simplest, the 30:30:30 framework focuses on three daily targets:

• Around 30g of protein per meal
• Around 30g of fibre per day
• 30 or more different plant foods across the week

Emma told Belle About Town: “This is the foundation of my Sunday Times best selling book, The 30g Plan. It’s a foundation that’s designed to support stable energy, balanced blood sugar, better digestion and long-term health. It’s not about restriction or perfection. It’s about giving your body what it actually needs to function well.”

Why midlife energy feels so fragile

During perimenopause and menopause, fluctuating hormones affect everything from sleep quality to insulin sensitivity. Many women find they become less tolerant of blood sugar peaks and troughs, even if they say they’ve ‘always eaten this way’.

Add in rushed breakfasts, carb-heavy lunches, insubstantial dinners, grazing in between meals and you get energy dips and resulting fatigue. A croissant at 8am, a sad salad at 1pm, pasta at 7pm sounds reasonable on paper. In reality, it often leads to mid-morning slumps, afternoon cravings and evening exhaustion. Women start to exercise less. They lose muscle mass. They put on weight around their middles. They constantly feel hangry, unsatiated and on edge.

Emma says: “The solution isn’t cutting carbs, drastically reducing calories or living on green juice and unsubstantiated supplements. It’s building filling meals that release energy slowly and consistently.”

The power of 30g protein per meal

“Protein is the most under-eaten macronutrient among midlife women,” Emma tells Belle. “Many of us are still eating child-sized portions without realising it. Protein supports muscle mass, which naturally declines with age. It also slows digestion, keeps you fuller for longer and helps stabilise blood sugar. When protein intake is too low, energy crashes often follow.

“Aiming for around 30g per meal is a useful anchor. That might look like eggs with a few extra egg whites from a carton mixed in at breakfast, a generous portion of chicken with a salad at lunch, or tofu, fish or beans at dinner. You don’t need to hit 30g perfectly every time, but consistently getting close makes a noticeable difference.”

Fibre: the missing link in energy

Fibre doesn’t get the spotlight protein does, but it’s just as important for energy, Emma says. Most adults in the UK struggle to reach even 18g a day, let alone the recommended 30g.

She tells us: “Fibre slows the release of glucose into the bloodstream, helping to prevent the highs and lows that leave you feeling wiped out. It also feeds your gut bacteria, which play a surprisingly important role in energy regulation, inflammation and even appetite, cravings and mood.

“High fibre diets are frequently linked to better metabolic health, improved insulin sensitivity and lower levels of fatigue (and, interestingly, better skin too!). Yet fibre only comes from plants (which are carbohydrates), which means if your diet is low in carbs and, therefore, plants, it’s almost certainly low in fibre too.”

Why plant diversity matters

Eating more plants isn’t just about vegetables. It includes fruits, beans, lentils, wholegrains, nuts, seeds, herbs and spices. Different plants feed different gut microbes. The more diverse your plant intake, the more resilient your gut ecosystem becomes. That diversity is associated with better digestion, improved immunity and more stable energy levels.

“Thirty plants a week might sound daunting,” says Emma. “But once you start counting herbs, spices, mixed salads and tinned pulses, it adds up quickly. You’ll be pleased to hear even dark chocolate, popcorn and coffee count! A lentil and vegetable soup alone or a pot of overnight oats with mixed seeds and some berries can easily contain eight to ten different plants.”

What this looks like in real life

Emma says: “This isn’t a diet. It’s a way of structuring meals.

“Breakfast becomes something that actually fuels you. Think protein-rich yogurt with berries, seeds and oats, or eggs with wholegrain toast and vegetables. Lunch is no longer a sad desk salad. It’s a balanced bowl with protein, fibre-rich carbs and plenty of plants.

“Dinner doesn’t need to be heavy to be satisfying. A bean-based chilli, salmon with lentils and greens, or tofu stir-fry with mixed vegetables ticks all the boxes. When meals are built this way, snacking often takes a back seat as it simply doesn’t feel necessary. Energy becomes more predictable. Cravings ease. And that constant tiredness starts to lift.”

Emma’s takeaway message

Emma says: “If you’re tired of being tired, start by looking at your plate. Not your supplements, not your willpower, not your motivation. Midlife energy thrives on nourishment, not restriction. The 30:30:30 method is a simple, realistic framework that helps women eat in a way that supports their changing physiology. We have to be realistic; it won’t fix everything overnight. But done consistently, it can help you feel more energised, more resilient and more like yourself again.

“And honestly, that’s a very good place to start.”
