3. Provide additional goal-specific information:
   • Muscle Gain: Training experience and desired gain rate
   • Fat Loss: Caloric deficit size and body fat percentage
   • Maintenance: Your maintenance focus
4. Enter your activity level - Training frequency and type.
5. Click "Calculate Protein Needs" to get your personalized recommendation.

Example 1: Muscle Gain

User: 28-year-old male

Stats: 180cm, 75kg

Goal: Muscle gain (intermediate, moderate rate)

Activity: Moderate (4 days/week strength training)

Result: 150-165g protein/day (2.0-2.2g/kg)

Example 2: Fat Loss

User: 35-year-old female

Stats: 165cm, 68kg (25% body fat)

Goal: Fat loss (moderate deficit)

Activity: Active (5 days/week mixed training)

Result: 125-140g protein/day (1.8-2.1g/kg)

About Protein Requirements

Protein is essential for muscle repair, growth, and overall health. Optimal intake varies based on multiple factors:

General Protein Guidelines:

• Sedentary adults: 0.8g per kg of body weight
• Recreational exercisers: 1.0-1.2g per kg
• Strength athletes: 1.4-2.0g per kg
• Endurance athletes: 1.2-1.6g per kg
• During caloric deficit: Higher end of ranges to preserve muscle

Factors Increasing Protein Needs:

• Caloric deficit (dieting/fat loss phases)
• Advanced age (to combat sarcopenia)
• High training volume/frequency
• Training while fasted
• Injury recovery

Protein Timing Considerations:

• Per meal: 20-40g (0.4g/kg/meal) for optimal muscle protein synthesis
• Post-workout: 20-40g within 2 hours of training
• Before bed: Casein protein can help overnight recovery

High-Quality Protein Sources:

Chicken breast

31g protein per 100g

Eggs

6g protein per large egg

Greek yogurt

10g protein per 100g

Lentils

9g protein per 100g cooked

Note: These recommendations are general guidelines. Individual needs may vary based on specific circumstances. Consult a dietitian for personalized advice.
