How Many Calories Should You Eat for Muscle Growth and Bulking?

When it comes to building muscle, there is no one-size-fits-all answer. Your calorie needs depend on:


Age – Younger individuals generally have faster metabolisms.


Weight and Height – Larger bodies burn more calories.


Activity Level – How much you move, both in and outside the gym, determines your energy expenditure.

To start, you need to understand how many calories you burn daily (Total Daily Energy Expenditure or TDEE). This includes your:

  • Basal Metabolic Rate (BMR) – Calories burned at rest.
  • Activity Levels – Workouts, daily movement, and physical tasks.

2. The Golden Rule: A Slight Caloric Surplus

To build muscle without gaining excess fat, aim for a slight caloric surplus of 5-10% above your TDEE.

  • If you burn 2,500 calories a day, add 125-250 extra calories.
  • This surplus provides your body with the energy needed to repair and grow muscle tissue.

🚫 Common Mistake: Many people think they need to “bulk” by eating thousands of extra calories. This leads to unwanted fat gain and makes cutting more difficult later. Slow and steady wins the race when building lean muscle.

3. Struggles with Eating for Muscle Growth

Here’s what most people struggle with when bulking:

  1. Overeating – Leading to fat gain.
  2. Undereating – Preventing muscle growth.
  3. Tracking calories and macros – It’s time-consuming and confusing.

Actionable Solution: Use the Calorie Calculator inside the GetFIT App's Premium Membership. With one quick input of your stats (age, weight, height, activity level), the app will calculate exactly how much you should eat to achieve your goals.
Better yet, our AI Coach ORION will design custom meal plans and suggest recipes tailored to your needs. No guesswork—just results.

4. How to Track Calories Without Going Crazy

Tracking your calorie intake doesn’t have to be overwhelming. Here’s how to make it simple:

  • Step 1: Start with Your TDEE – Use tools like ORION in the GetFIT App to calculate it instantly.
  • Step 2: Divide Your Calories into Macros:
    • Protein: 1.6–2.2 g per kg of body weight.
    • Carbs: Fuel your workouts with complex carbs.
    • Fats: Essential for hormones and overall health.

🔹 Pro Tip: Focus on high-protein meals to build and maintain muscle. If you struggle with ideas, the GetFIT App's Premium Membership includes hundreds of protein-rich recipes and custom grocery lists so you always know what to eat.

5. Why High Protein Is Non-Negotiable for Muscle Growth

Protein is the building block of muscle. Without enough protein, your body won’t repair and build new muscle fibers after workouts.

Aim for 1.6–2.2 grams of protein per kg of body weight daily. For example:

  • A 70 kg person needs around 112–154 grams of protein per day.

Some great protein-rich foods include:

  • Eggs
  • Chicken, turkey, and lean beef
  • Greek yogurt
  • Protein shakes
