Energy & Performance — Food for Your Best Body and Mind

Why you feel tired — the nutritional causes

Chronic low energy is almost always nutritional before it is anything else. The top dietary causes of fatigue:

• Blood sugar instability: refined carbs cause spikes then crashes — the energy rollercoaster
• Iron deficiency: most common nutrient deficiency — fatigue is the primary symptom
• Vitamin D deficiency: impairs mitochondrial energy production directly
• Dehydration: even 1–2% dehydration reduces cognitive performance and increases fatigue
• Insufficient protein: protein provides amino acids for neurotransmitter production

All-day energy foods

These foods provide slow, sustained energy release without the crash:

Pre-workout nutrition

Fuel your workout correctly and performance, recovery, and muscle gain all improve. The key is timing and macronutrient balance:

• 1–2 hours before: complex carbs + protein — oats with Greek yoghurt, rice with chicken, banana with eggs
• 30 min before: quick carb if needed — banana, date, handful of raisins
• Avoid: high fat or high fibre immediately before training — slows digestion and causes discomfort
• Caffeine timing: 200–400mg caffeine 30–60 min before training is the most studied performance enhancer

Post-workout recovery nutrition

The recovery window (30–60 minutes after training) is when muscle protein synthesis is at its peak:

• Protein: 20–40g within 60 minutes — whey, chicken, Greek yoghurt, eggs, or plant sources
• Carbs: replenish glycogen — rice, oats, fruit, or sweet potato
• Omega-3: reduces exercise-induced inflammation and muscle soreness
• Tart cherry juice: studied for reducing muscle damage and soreness

Brain-boosting foods

Your brain is 60% fat and runs on glucose and ketones. Feed it the right fuel and cognitive function, memory, and mood all improve:
