Protein Intake for Cutting Calculator
When you’re in a cutting phase, the goal is simple: lose fat while preserving muscle mass. To achieve this, your nutrition strategy plays a key role, especially your protein intake.
Protein is the most important macronutrient during cutting because it:
- Prevents muscle breakdown when in a calorie deficit
- Helps you stay fuller longer, reducing cravings
- Supports recovery and performance in the gym
The Protein Intake for Cutting Calculator helps you determine exactly how much protein you need based on your weight, activity level, and goals. This ensures you maintain lean muscle while shedding fat effectively.
