Protein Daily Intake Calculator

Getting the right amount of protein each day is crucial for building muscle, losing fat, improving recovery, and maintaining a healthy body. However, everyone’s protein requirements are different — they depend on factors like weight, age, activity level, and personal fitness goals.

The Protein Daily Intake Calculator is an interactive tool designed to help you quickly determine your ideal protein intake in grams per day. Whether you’re an athlete, someone looking to build lean muscle, or simply want to eat healthier, this calculator provides an accurate daily protein range tailored to your body and goals.

🧠 What Is the Protein Daily Intake Calculator?

The Protein Daily Intake Calculator is a simple yet powerful tool that estimates how much protein you need every day to stay healthy and meet your fitness objectives. It uses scientifically backed formulas that factor in:

• Gender (for slight metabolic variations)
• Age (protein needs rise as you get older)
• Weight (the foundation for protein calculations)
• Activity level (more activity = more protein required)
• Fitness goal (muscle gain, fat loss, maintenance, endurance, or aging support)

By analyzing your input, the calculator instantly provides four important metrics:

1. Minimum protein requirement – to prevent deficiency.
2. Recommended daily protein – the optimal intake for your goal.
3. Maximum safe limit – the highest safe daily amount.
4. Per meal target – how much protein to eat per meal for best absorption.

🧩 Example: Calculating Protein for a 70 kg Active Male

Let’s walk through a real-world example.

Input Details:

• Gender: Male
• Age: 28
• Weight: 70 kg
• Activity Level: Active (6–7 days/week)
• Goal: Build Muscle

Results:

• Minimum Protein: 98 g/day
• Recommended Protein: 112 g/day
• Maximum Safe Protein: 154 g/day
• Per Meal Target: 28 g (assuming 4 meals per day)

Formula Used: 1.6–2.2 g/kg (for muscle gain)

This means our example person should aim for around 110–130 grams of protein per day to effectively build muscle without overconsumption.
