Clean Bulking Bodybuilding Diet for Lean Muscle Growth

Bulking doesn’t have to mean gaining unwanted fat. If your goal is to add muscle without getting fluffy, then a clean bulking bodybuilding diet for lean muscle growth is the way to go. Let’s break down how to eat smart, grow strong, and stay lean.

What Is Clean Bulking?

Clean bulking refers to increasing your calorie intake slightly above maintenance to build muscle gradually, while minimizing fat gain. Unlike “dirty bulking,” where people eat anything in sight, clean bulking emphasizes quality foods, controlled portions, and nutrient balance.

How Many Calories Do You Need?

First, estimate your maintenance calories (use any TDEE calculator), then add a modest surplus of 250–500 calories per day. This small increase allows your body to focus on muscle synthesis without excessive fat storage.

For example:
If your maintenance is 2500 calories → Aim for 2750–3000 daily calories for lean bulking.
