## What is EICalc?

Calculate Your Personalized Daily Calorie Target

Stop guessing your calorie needs. This science-based calculator determines your optimal daily calorie intake using research-backed formulas—no tracking or logging required.

What Makes This Calculator Different:

• Unlike calorie tracking apps, this tool helps you calculate your personalized calorie target once, based on your unique body composition and lifestyle. Enter your metrics, get your number, and use it to plan your nutrition strategy.

Science-Backed Methodology:

• Our calculator uses the Cunningham formula (1991) combined with individualized factors:
- FFM-Based BMR – More accurate than simple age/weight formulas
- Gender-Specific Activity Levels – Separate PAL values for men and women
- Training Energy Expenditure – Accounts for intensive workout sessions
- Thermic Effect of Food (TEF) – Adjusts for diet quality and body composition
- Flexible Goal Setting – Calculate for maintenance, deficit, or surplus

Perfect For:

• Athletes planning nutrition periodization
• Fitness enthusiasts starting a cut or bulk
• Anyone who wants to understand their calorie needs
• Coaches calculating client targets

How It Works:

• Enter your body weight and body fat percentage
• Select your biological sex and activity level
• Add training days per week and session duration
• Choose your goal (maintenance/deficit/surplus)
• Get your personalized daily calorie target

Advanced Features:

• Separate calculations for rest days and training days
• Adaptive thermogenesis adjustment for lean individuals
• TEF customization based on diet quality
• All formulas and calculations transparently displayed

This is a calculator, not a food diary. Calculate your target, then use it however works best for you—whether that's meal planning, flexible eating, or working with a nutrition coach.
