5 Nutrition Principles That Actually Work
Forget fad diets and conflicting advice. These five evidence-based nutrition principles are all you need to fuel performance, build muscle, and stay lean year-round.
The nutrition space is noisy. Carnivore vs. vegan. Keto vs. high-carb. Eat six meals a day vs. fast for 16 hours. It's exhausting. After 8 years of working with hundreds of clients, here are the only five principles that have consistently moved the needle.
1. Calories Are Still King
No matter what diet you follow, energy balance determines whether you gain or lose weight. To lose fat, eat less than you burn. To build muscle, eat slightly more. Everything else is secondary.
2. Prioritise Protein
Aim for 1.6–2.2g of protein per kilogram of bodyweight daily. Protein preserves muscle during a cut, drives muscle growth during a bulk, and keeps you full longer than carbs or fat. It's the one macro most people consistently under-eat.
3. Don't Fear Carbohydrates
Carbs are your primary fuel for intense training. Athletes who slash carbs often find their performance tanks and recovery suffers. Time your carbs around training for best results.
4. Eat Mostly Whole Foods
You don't need to eat perfectly, but the bulk of your diet should come from minimally processed foods. Lean meats, fish, eggs, rice, potatoes, oats, vegetables, and fruit. These foods are nutrient-dense, satiating, and make hitting your macros easy.
5. Consistency Beats Perfection
The best diet is one you can maintain for years, not weeks. A plan that's 80% optimal and 100% sustainable will always beat a perfect plan you abandon after three weeks. Build habits, not streaks.
