Lean Bulk Meal Plan: Build Muscle, Minimise Fat
The old-school "dirty bulk" — eat everything in sight, then diet the fat off later — is an inefficient way to build muscle. A lean bulk is smarter: a modest calorie surplus with high protein, so you gain mostly muscle and minimal fat. Here's how to structure it.
What Is a Lean Bulk?
A lean bulk means eating slightly above your maintenance calories — enough to fuel muscle growth, but not so much that you pile on fat. The two pillars:
- A modest calorie surplus — typically around 200–400 calories above maintenance
- High protein — to ensure the surplus builds muscle, not just fat
Pair that with progressive resistance training and you grow steadily and leanly.
How to Structure Your Lean Bulk Meal Plan
- Protein: around 1.6–2.2g per kg of bodyweight daily (30g+ per meal)
- Calories: a controlled surplus — track for a couple of weeks and adjust based on the scale and mirror
- Carbs: your main fuel for training — keep them moderate to high
- Fats: enough for hormones and health, but they're calorie-dense so don't overdo it
- Consistency: the same intake daily beats wild swings
A Lean Bulk Made Simple
The hardest part of a lean bulk is eating enough protein and calories consistently without resorting to junk. Our Large range is purpose-built for this:
- 600–750 calories per meal — the controlled surplus you need
- 40g+ protein per meal — well above the baseline
- Real whole-food ingredients, not empty calories
- Fully portioned, so your numbers stay consistent day to day
Stack these across your day and your lean bulk runs on autopilot.
Frequently Asked Questions
How big should my calorie surplus be?
Modest — around 200–400 calories over maintenance is usually enough to build muscle while limiting fat gain.
How much protein for a lean bulk?
Around 1.6–2.2g per kg bodyweight daily.
Will I still gain some fat?
A little fat gain is normal in any surplus. A lean bulk keeps it minimal by avoiding an excessive surplus.
How long should a lean bulk last?
Often several months — muscle is built slowly, so patience pays off.
