Bulking is when you eat more food than usual to help your body grow bigger and stronger. The goal is to gain muscle, not just weight. But to do this the right way, you need to understand how to calculate bulking calories. Knowing the right number of calories to eat each day will help you build muscle without gaining too much fat.
With the MyFitnessCoach app, it's even easier! Our app has tools to help you track your food, workouts, and progress. You can even build your own workouts and follow custom diet plans. Let’s explore everything you need to know about calculating your bulking calories.
Why Calculating Bulking Calories Is Important
Eating too few calories won’t help you build muscle. Eating too much may cause you to gain fat. That’s why it’s important to find the perfect amount of calories to help your body grow. This is called a calorie surplus eating more calories than your body needs to stay the same.
How Bulking Helps
- Helps gain muscle
- Supports muscle growth
- Boosts your energy during workouts
- Improves overall body composition
But the trick is to eat just enough extra calories, not too much.
How to Calculate Bulking Calories Step by Step
To learn how to calculate bulking calories, follow these simple steps:
Step 1: Know Your Maintenance Calories
Your maintenance calories are the number of calories your body needs to stay the same weight. This depends on your:
- Age
- Gender
- Height
- Body weight
- Activity level
You can find your maintenance calories using the Mifflin St Jeor equation.
Step 2: Add a Calorie Surplus
Once you know your maintenance calories, add a small surplus:
- Beginners: Add 250–300 calories per day
- Advanced lifters: Add 100–200 calories per day
This small increase will help you build muscle without adding too much fat.
Step 3: Track Your Progress
It’s important to track your weight and muscle mass weekly. If you're gaining too fast, reduce your calories slightly. If you're not gaining at all, increase them a bit.
You can do all of this with the Food Logger and Fitness Tracker in the MyFitnessCoach app!
Understanding Your Daily Calorie Needs
Your total calorie intake includes everything you eat and drink. To build muscle, your body needs more fuel. So let’s break it down:
- Protein: For building and repairing muscles
- Carbs: For energy
- Fats: For hormones and overall health
The right balance helps your body grow strong and healthy. The number of calories per day you need depends on your goals, metabolism, and how active you are.
Using a Calorie Calculator
You can use calorie calculators online or in apps to get a good starting point. But they don’t always tell the full story. You should adjust your calories based on how your body responds.
To make it super easy, the MyFitnessCoach app calculates your calories for you! You can even choose from different goals like weight gain, muscle building, or even lose weight (if you want to cut later).
Here’s what you’ll need to enter into a calculator:
- Body fat percentage (optional but helpful)
- Weight and height
- Age and gender
- Activity level
Then it will tell you how many daily calories you need.
Macronutrient Breakdown for Bulking
Once you know how many calories to eat, divide them into macronutrients:
Protein
- Aim for 1.0–1.2 grams per pound of body weight
- Helps build and repair muscles
Carbs
- Main energy source
- Should be your biggest macronutrient
Fats
- Important for hormones and energy
- Aim for 20–30% of your total calories
