Why Diet is 70% of Your Fat Loss Result
No training programme can outrun a poor diet. Fat loss is fundamentally about energy balance — consuming fewer calories than you expend. But the quality of your food determines whether you lose fat or muscle, whether your training performance suffers, and how sustainable your progress is.
The goal is a moderate calorie deficit with high protein intake, timed around your training to maximise performance and recovery while promoting fat oxidation.
Key numbers: Aim for a 300–500 calorie daily deficit. Consume 1.6–2.2g protein per kg bodyweight. Get 25–35g fibre daily. Drink 2.5–3.5 litres of water.
Macro Split for Gym Fat Loss
| Macro | Target | Best Sources |
|---|---|---|
| Protein | 1.6–2.2g / kg bodyweight | Chicken, eggs, fish, Greek yoghurt, whey |
| Carbohydrates | 2–3g / kg bodyweight | Oats, rice, sweet potato, fruit, beans |
| Fats | 0.8–1.2g / kg bodyweight | Avocado, nuts, olive oil, salmon, eggs |
What to Eat Before and After Training
Pre-Workout (60–90 min before)
Protein + complex carbs. Examples: chicken and rice, oats with protein powder, eggs on wholegrain toast. Avoid high-fat meals — they slow digestion and reduce energy availability.
During Training
Water only for sessions under 60 minutes. For longer sessions add electrolytes. Avoid sugar drinks unless doing endurance work over 90 minutes.
Post-Workout (within 30 min)
20–40g protein immediately post-session. Moderate carbs to replenish glycogen. Examples: protein shake + banana, Greek yoghurt with berries, chicken and sweet potato.
Evening Meal
High protein, moderate fat, lower carbs. Examples: salmon with vegetables, lean beef stir-fry, turkey with salad. Reduce carbs at night unless training in the evening.
