Eating for
Muscle Growth
You can't build something from nothing. Muscle growth requires both the right training signal and the nutritional environment to act on it. One without the other stalls the process.
Calorie surplus
How much above
maintenance?
maintenance?
Lean bulk — 200–300 kcal
Slow, controlled muscle gain with minimal fat accumulation. Best for most people.
0.2–0.4kgper week
Moderate bulk — 400–500 kcal
Faster results but expect some fat gain alongside the muscle.
0.4–0.6kgper week
Dirty bulk — 700+ kcal
Muscle growth doesn't scale with more food. You'll gain fat rapidly and need a long cut after.

Per kilogram of bodyweight per day. These are working ranges — adjust based on response.
Protein
1.8–2g/kg
Carbohydrates

Fat
0.8–1g/kg
Carbohydrates fuel the training that creates the growth signal. Fat supports hormone production. Protein provides the material. None of them are optional.

01
Eat enough — consistently
Undereating three days, overeating on weekends is not a surplus. Consistent intake over weeks is what drives steady muscle growth.
Most commonly missed
02
Distribute protein across meals
3–4 protein-anchored meals spread through the day keeps muscle protein synthesis elevated. One large hit at dinner doesn't cut it.
03
Prioritise carbs around training
Pre-training carbs fuel performance. Post-training carbs replenish glycogen and support recovery. Both matter for maximising the session.

Eating in a surplus with low protein
A calorie surplus without adequate protein is a fat gain programme, not a muscle gain programme. The surplus only works if protein is already covered.
×
Inconsistent intake
Feast-famine cycles confuse the body's adaptation response. Steady, slight surplus beats chaotic overeating every time.
×
Ditching carbs while trying to build muscle
Carbs fuel training intensity. Low-carb and high performance rarely coexist — and performance drives the growth signal.
The Naked Truth
You're training hard and wondering why the muscle isn't coming. You're also eating at maintenance on good days and in a deficit on bad ones. You can't build on nothing.
A small, consistent surplus with high protein is the whole formula. Not exciting — just effective.
