Why Nutrition Is the Missing Half of Your Fitness Plan
Training hard but not seeing results is one of the most common frustrations in fitness. In the vast majority of cases, the issue is nutrition — not effort. What you eat before, during, and after training determines how well your body recovers, builds, and adapts. At Core and More Fitness in Clapham, our nutrition coaching is integrated into every training programme rather than offered as a bolt-on.
Macronutrients Explained: Protein, Carbs and Fats
Protein — The Builder
Protein is the raw material for muscle repair and growth. Without adequate protein, your training stimulus goes to waste — you break the muscle down in the gym but cannot rebuild it efficiently. For active adults, the evidence supports 1.6–2.2g of protein per kilogram of bodyweight daily. Practical sources include eggs, chicken, fish, Greek yoghurt, cottage cheese, and quality protein supplements when whole food is impractical.
Carbohydrates — The Fuel
Carbohydrates are the primary fuel for high-intensity training. Depleted glycogen stores reduce performance, impair recovery, and — in severe cases — lead to muscle breakdown for energy. The popular demonisation of carbs ignores context: the right carbohydrates at the right times support training quality significantly. Oats, sweet potato, rice, fruit, and wholegrain bread are excellent training fuels.
Fats — The Regulator
Dietary fat supports hormone production (including testosterone), fat-soluble vitamin absorption, and sustained energy between meals. The key is source quality — olive oil, avocado, nuts, oily fish, and eggs provide healthy fats that support the hormonal environment for body composition improvement.
Pre and Post Workout Nutrition
Pre-Workout
Eating 60–90 minutes before training gives your body the fuel it needs without causing digestive discomfort during exercise. A combination of moderate carbohydrates and protein is optimal — for example, oats with Greek yoghurt, a banana with peanut butter, or a chicken wrap. Training fasted may suit some individuals for short sessions but typically reduces performance in longer or more intense workouts.
Post-Workout
The post-workout window is real but broader than once thought — within 2 hours of training is the practical guidance. Prioritise protein (25–40g) alongside carbohydrates to replenish glycogen and initiate muscle protein synthesis. A meal of salmon with rice and vegetables, or a protein shake followed by a proper meal, both work well.
Common Nutrition Mistakes We See in Clapham Clients
- Eating too little protein while training hard — resulting in muscle loss disguised as weight loss
- Skipping breakfast before morning sessions then overeating at lunch
- Using exercise as licence to overeat — 45 minutes of training burns far fewer calories than most people think
- Following extreme elimination diets that are unsustainable beyond 4–6 weeks
- Neglecting hydration — even mild dehydration measurably impairs strength and endurance
