The old approach to building muscle was simple: eat everything, get big, worry about the fat later. It works, but half of what you gain is fat that takes months to lose. A lean bulk is the smarter version. You eat just enough above maintenance to fuel muscle growth, and no more.
Quick answer
A lean bulk means eating about 250 to 400 calories above maintenance, with 1.6 to 2.2 g of protein per kg of body weight, while training with progressive overload. Aim to gain about 0.25 to 0.5 percent of your body weight per week. Faster than that is mostly fat.
Lean bulk vs dirty bulk
| Lean bulk | Dirty bulk | |
| Calorie surplus | 250–400 kcal | 700+ kcal |
| Food quality | Mostly whole foods | Anything goes |
| Rate of gain | Slow and steady | Fast |
| Fat gained | Minimal | Significant |
| Cutting phase needed afterwards | Short or none | Long |
Step 1: Set your calories
Find your maintenance calories with a TDEE calculator, then add 250 to 400. A 70 kg man who trains four times a week might maintain at about 2,500 calories and lean bulk at 2,750 to 2,900.
Beginners can use the higher end, since they build muscle faster. Experienced lifters should stay at the lower end.
Step 2: Set your macros
| Macro | Target | For a 70 kg person at 2,800 kcal |
| Protein | 1.6–2.2 g per kg | 115–155 g |
| Fat | 0.8–1 g per kg | 55–70 g |
| Carbs | The remaining calories | About 380–420 g |
Carbs do the heavy lifting in a bulk. They fuel hard training and help recovery, so this is not the time for low-carb eating.
A sample lean bulk day (about 2,800 kcal, ~150 g protein)
| Meal | What to eat |
| Breakfast | 4-egg omelette, 3 slices multigrain toast, banana, glass of milk |
| Mid-morning | Peanut butter sandwich, 1 fruit |
| Lunch | 1 pack chicken breast, 1.5 cups rice, dal, sabzi, curd |
| Pre-workout | Banana, handful of dates and nuts |
| Dinner | 1 pack chicken steak or a salmon fillet, 3 rotis, vegetables |
| Before bed | Hung curd or a glass of milk |
Best foods for a lean bulk
- Protein: chicken breast, eggs, fish, paneer, curd, dal.
- Carbs: rice, roti, oats, potatoes, sweet potatoes, bananas, poha.
- Fats: olive oil, nuts, peanut butter, salmon, ghee in moderation.
Salmon earns a special mention: it brings both protein and calorie-dense healthy fats, which makes hitting a surplus easier without junk food.
Track and adjust
Weigh yourself three or four mornings a week and compare weekly averages.
- Gaining less than 0.25 percent a week: add 100 to 150 calories.
- Gaining more than 0.5 percent a week: remove 100 to 150 calories.
- Waist growing faster than your lifts: your surplus is too large.
For a 70 kg person, the target is roughly 0.7 to 1.4 kg a month.
If you struggle to eat enough
- Add a tablespoon of olive oil or ghee to meals for easy calories.
- Drink some calories: milk, lassi or a banana smoothie.
- Eat more often instead of forcing huge meals.
- Keep ready protein in the fridge so no meal is skipped.
FAQs
How long should a lean bulk last? Usually four to eight months, or until you are no longer comfortable with your body fat.
Can I lean bulk without supplements? Yes. Food covers everything. Creatine is the one supplement with strong evidence, and it is optional.
Will I gain some fat? A little is normal. The goal is to keep it small.
Protein that keeps up with your bulk
A bulk needs 120 g or more of protein every day. Meatigo’s Everyday Chicken Breast and Everyday Chicken Steak each give 32 g per pack, and a Norwegian Atlantic Salmon Fillet adds protein and healthy fats in one go.
