What to Eat for Energy and Focus: Macronutrient Guide

If you struggle with brain fog, low energy, mood swings, or hormonal imbalances — or you’re a leader seeking to improve employee cognitive performance — your brain health depends on nutrient-dense macronutrients that support not only brain cells but also the crucial gut-brain axis.

Macronutrients — carbohydrates, fats, and proteins — provide the essential building blocks and nourishment your brain and gut need to function optimally. The quality and balance of these nutrients are key to improving mental clarity, emotional resilience, and sustained energy.

What Are Macronutrients & Why Do They Matter for Brain & Gut Health?

Macronutrients are the nutrients you need in large amounts to sustain life and promote health. They:

• Provide glucose and other nutrients that fuel your brain

• Support healthy gut microbiome which communicate directly with your brain through the gut-brain axis

• Build the structural components of neurons, hormones, and neurotransmitters

• Regulate inflammation, mood, and cognitive function

A balanced intake of nutrient-dense macronutrients strengthens the gut-brain connection, which is vital for mental well-being, hormonal balance, and energy regulation.

🧠 Protein: Essential for Neurotransmitters, Hormones & Resilience

Protein builds more than muscle. It provides the amino acids needed to create dopamine, serotonin, acetylcholine, and stress-regulating hormones.

Whether omnivore of vegetarian, it’s essential to get sufficient protein for your brain and body. And quality matters. Choose grass-fed, pasture-raised, or wild-caught sources, instead of factory-farmed meat and farm-raised fish.  Choose nature’s plant-based protein rather than man-made (artificial meat burgers)

✅ Best sources:

• Wild-caught fish (salmon, sardines, mackerel)
• Pasture-raised poultry
• Lean meats – bison, elk, venison – occasional grass-fed beef and lamb
• Pasture-raised eggs
• Properly prepared legumes or tempeh

These proteins:

• Provide all 9 essential amino acids
• Support mental clarity, mood stability, immune strength
• Deliver nutrients like B12, iron, zinc, and creatine often lacking in plant-only diets

Vegetarians:

It’s important to consume a variety of plant proteins to meet your amino acid needs. Some top vegetarian protein sources include:

• Lentils and legumes (beans, chickpeas, peas)
• Tofu, tempeh, and edamame
• Quinoa and amaranth
• Nuts and seeds (chia, hemp, pumpkin)
• Whole grains (brown rice, oats, barley)

While many plant proteins are incomplete individually, combining diverse sources throughout the day helps ensure you get all essential amino acids.

👉 Brain Tip: For optimal brain and hormone health, emphasize diversity: fatty fish and poultry most days, with lean wild red meat occasionally.

🧠 Carbohydrates: Natural Glucose + Fiber for Brain Energy and Gut Health

Carbs are your brain’s preferred fuel—but quality matters. We want natural glucose, not refined, man-made sugars that spike and crash energy.

Carbohydrates from nature come from whole foods loaded with fiber and micronutrients that nourish the gut-brain axis, regulate blood sugar, and support neurotransmitter production.

✅ Best sources:

• Leafy greens and cruciferous vegetables
• Colorful vegetables
• Tubers and root vegetables
• Legumes
• Fruits (moderation)
• Whole grains

These carbs:

• Provide clean brain fuel (glucose)
• Feed the gut microbiome, boosting mood and immunity
• Support tissue repair, neurotransmitter production, and joint health

👉 Brain Tip: Chronically low-carb diets may lower serotonin and GABA levels, leading to anxiety or sleep issues. Don’t fear carbs—skip man-made carbs and choose carbs from nature

🔢 How Much Macronutrients Do You Need?

Your ideal macronutrient ratio is unique, influenced by genetics, lifestyle, stress, age, and digestive health.

Here’s a general range to support brain function, blood sugar stability, and o

• Carbohydrates: 30–40%
• Fats: 30–40%
• Protein: 20–50%

Use these as starting points and adjust based on your body’s feedback.

🔎 How to Find Your Bioindividual Macronutrient Ratio

The ideal ratio should help you feel:

• Energized and focused
• Calm and emotionally balanced
• Satiated, without cravings or crashes

Use the guide below to assess:

Observe these signals to gauge if your macronutrient balance supports your brain and gut health

Steps to optimize your balance:

1. Track your macros with apps like Cronometer or MyFitnessPal

2. Keep a Food & Mood Journal for 1–3 hours after meals for 3 – 5 days to connect what you eat and how you feel

3. Adjust your ratios based on your physical and mental responses over days or weeks

🌳 Choose Nutrient-Dense, Whole Foods for Brain & Gut Health

Quality matters as much as quantity:

• 🌈 Eat a variety: Different proteins, seasonal carbs

• 🐄 Choose ethical animal foods: Grass-fed, pasture-raised, wild-caught

• 🍅 Eat seasonal and local produce to maximize nutrient density and minimize toxins

• 🚫 Avoid processed foods, refined sugars, and industrial seed oils

Refer to the EWG Dirty Dozen & Clean 15 for produce guidance.

🧠 Final Thought: Your Brain Thrives on Nutrient Dense Food

Macronutrients are more than just numbers—they’re the building blocks of your energy, emotions, and resilience. By choosing carbs, fats, and proteins from nature in the best ratio for you, you build a lifestyle that supports:

• Mental clarity and productivity

• Emotional resilience

• Hormonal balance

• Sustained energy and vitality

Start tuning into your body’s signals, nourish your gut and brain with quality carbs, fats, and proteins, and experience lasting improvements in your health and well-being.
