Advanced TDEE & Nutrition Planner
Disclaimer: This calculator provides estimated calorie needs and nutrition guidance based on standard metabolic formulas. It is for informational purposes only and should not replace professional medical or dietary advice.
Calculate your Total Daily Energy Expenditure (TDEE), analyze calorie balance, and generate personalized nutrition plans based on your fitness goals, activity level, and body composition.
Use Cases
- • Calculate daily calorie needs (TDEE)
- • Plan weight loss or muscle gain strategies
- • Analyze calorie surplus or deficit
- • Track progress toward target weight
- • Compare multiple fitness scenarios
Key Features
- • BMI & healthy weight range calculation
- • BMR (Mifflin-St Jeor & Katch-McArdle)
- • TDEE based on activity level
- • Calorie goal (deficit/surplus)
- • Macronutrient breakdown (protein, carbs, fat)
- • Scenario comparison (multi-input)
- • Sensitivity analysis (weight vs TDEE)
- • Progress tracking toward target weight
- • Charts & data visualization
- • Export results (CSV & PDF)
Formulas Used
- • BMI = Weight / Height²
- • BMR (Mifflin-St Jeor Equation)
- • BMR (Katch-McArdle with body fat)
- • TDEE = BMR × Activity Factor
- • Calorie Goal = TDEE ± Adjustment
- • Macronutrients based on calorie split
Calorie Strategy
- • Weight Loss → ~500 kcal deficit
- • Maintenance → Calories ≈ TDEE
- • Muscle Gain → ~250 kcal surplus
- • Adjust based on progress & lifestyle
Health Insights
- • Calorie balance determines weight change
- • Protein supports muscle preservation
- • Activity level impacts daily calorie needs
- • Gradual progress is more sustainable
- • Health conditions may affect metabolism
