Nutrition foundations
What nutrition actually is, why food quality matters more than calorie counting, and the hierarchy that simplifies most decisions.
Energy & calories
How the body uses and stores energy, why energy balance still governs body weight, and why crash diets reliably fail.
Protein
How much protein you need, why it is the most important macronutrient for active people, and the best sources.
Carbohydrates
The primary fuel for brain and intense exercise, why blood glucose stability matters, and when low-carb diets make sense.
Fats
Why dietary fat is essential, why fat quality matters far more than quantity, and the omega-3 evidence.
Fibre & gut health
What fibre does, why the gut microbiome is a new frontier in health, and how to feed both effectively.
Vitamins
What vitamins do, which deficiencies are genuinely common, and when supplementation is warranted.
Minerals
The essential minerals, common deficiencies, and where to find them in food.
Hydration
How much water you need, when dehydration actually impairs performance, and when electrolytes matter.
Food quality & processing
The NOVA classification, why ultra-processed foods are a distinct health problem, and a practical rule for navigating them.
Meal planning & cooking
The practical principles that make good nutrition consistent rather than effortful.
