What to eat to build muscle

You've been training hard, eating "pretty clean", and the scale won't budge — or worse, you're putting on softness instead of muscle. The truth is, you can't out-train a diet that doesn't feed muscle. Build the right plate and your training finally has the raw materials to turn into the body you're working for.

Building muscle isn't about chicken and broccoli forever, or choking down a litre of shakes. It comes down to four simple levers: a slight calorie surplus, enough protein, smart carbs and fats, and a routine you can actually repeat. Here's exactly what to eat — and a sample day you can copy tomorrow.

Eat a slight calorie surplus (not a free-for-all)

Muscle is tissue you build, and building costs energy. To grow, most people need to eat a little above maintenance — but the key word is slight.

• Aim for roughly +250 to +500 kcal a day above your maintenance (your TDEE).
• That should translate to gaining about 0.25–0.5 kg per week. Faster than that is mostly fat, not muscle.
• Brand-new or returning to training? You can often build muscle at maintenance ("newbie gains") — so don't rush the surplus.

A bigger surplus does not build muscle faster; it just adds fat you'll later have to diet off. If your goal is to lose fat and gain muscle at once, that's a different game — read body recomposition.

Hit your protein target every day

Protein is the one nutrient muscle is literally made of, and it's the lever with the most evidence behind it. Pooled research points to a daily target of around 1.6–2.2 g of protein per kg of bodyweight for people lifting weights, with gains plateauing near 1.6 g/kg in the data.

For an 80 kg person that's roughly 130–175 g a day. Spread it across 3–4 meals of 25–40 g each — your body uses protein better in regular doses than in one giant hit.

Don't fear carbs — they fuel the work

Carbs are the cheap fuel that lets you lift heavy enough to actually trigger growth, and they help your body hold onto protein. Under-eat them and your sessions get flat and your strength stalls.

• Build most meals around starchy carbs: rice, oats, potatoes, pasta, wholegrain bread.
• The NHS suggests starchy foods make up just over a third of what you eat — that lines up well with a muscle-building plate.
• Time more carbs around training if it helps your energy; see what to eat before and after a workout.

Keep fats moderate for hormones and health

Fats aren't the enemy — they support hormone production and help you absorb key vitamins. Keep them at roughly 20–30% of your calories, leaning on the good stuff: olive oil, nuts, seeds, oily fish, avocado. Don't drop fat too low, or recovery and mood take the hit.

A simple sample muscle-building day

Here's an 80 kg lifter's day at about 2,600 kcal and ~150 g protein — adjust portions to your own numbers:

1. Breakfast: 3 eggs, 80 g oats, banana, milk (~35 g protein)
2. Lunch: 150 g chicken, large jacket potato, mixed veg, olive oil (~45 g)
3. Snack: Greek yoghurt + berries + handful of nuts (~20 g)
4. Post-training: 150 g salmon, rice, broccoli (~40 g)
5. Evening: Cottage cheese or a casein-rich snack (~15 g)

This is the quiet engine behind the Method: we set your surplus and protein from your real numbers, then adjust every week as your bodyweight and lifts respond — so you're never guessing whether you're eating enough. If you'd rather have the plate and the plan built for you and tuned to your progress, the muscle-growth programme does exactly that. Feed the work, and your body has no choice but to grow.
