What Are Macros and Why Do They Matter?
What Are Macronutrients (Macros)?
Macros are nutrients you need in large amounts. The big three are protein, carbohydrates, and fat. Each has a unique role in supporting energy, muscle, and overall health.
Protein, Carbohydrates, and Fats Explained
- Protein: Crucial for muscle repair and growth.
- Carbohydrates: Your body’s main energy source.
- Fat: Supports hormone balance and brain function.
How to Calculate Your Macros?
Input Your Details (Age, Sex, Height, Weight)
Start by entering your basic stats. These are the foundation of your macro plan.
Choose Your Activity Level
Your daily movement matters. Whether you’re sedentary or highly active, your macro plan should reflect that.
Set Your Goal (Weight Loss, Maintenance, Muscle Gain)
Are you trying to shed fat, build muscle, or stay steady? Your goal shapes your macro breakdown.

This popular macro split (40% protein, 40% carbs, 20% fat) works well for fat loss and balanced nutrition. You can always adjust based on personal needs.
Calculate Your Calories for Bodybuilding or Fat Loss
If you’re building muscle, eat more calories and increase macros. For fat loss, use a deficit while keeping protein intake high.
Macros for Different Fitness Goals
Macros for Weight Loss
Lower carbs, raise protein, and maintain healthy fats. Stay in a calorie deficit without sacrificing muscle.
Macros for Muscle Gain
Increase total calories, especially from protein and carbs, to support recovery and growth.
Macros for Maintenance
Keep everything balanced. You’re not trying to gain or lose—just maintain.
Macro Ratios for Each Goal
- Weight Loss: 40% protein / 30% carbs / 30% fat
- Muscle Gain: 30% protein / 50% carbs / 20% fat
- Maintenance: 30% protein / 40% carbs / 30% fat
