Complete Calorie & Metabolism Guide
🔥 Understanding Your Metabolism
Your daily caloric needs consist of multiple components that together determine how many calories you burn each day.
BMR (Basal Metabolic Rate)
- • Definition: Calories burned at complete rest
- • Percentage: 60-75% of total daily calories
- • Functions: Breathing, circulation, cell production
- • Factors: Age, gender, weight, muscle mass
TDEE (Total Daily Energy Expenditure)
- • Formula: BMR × Activity Factor
- • Components: BMR + activity + digestion
- • Variable: Changes with lifestyle and exercise
- • Purpose: Maintenance calorie level
Activity Multipliers
- • Sedentary: 1.2 (desk job, minimal exercise)
- • Light: 1.375 (exercise 1-3 days/week)
- • Moderate: 1.55 (exercise 3-5 days/week)
- • Active: 1.725 (exercise 6-7 days/week)
- • Very Active: 1.9 (physical job + training)
🎯 Goal-Based Strategies
⚖️ Weight Loss Strategy
- • Deficit: 500 calories/day = 1 lb/week loss
- • Safe Range: 1-2 lbs (0.5-1 kg) per week
- • Minimum: Never below BMR × 0.8
- • Focus: Sustainable, gradual reduction
💪 Muscle Gain Strategy
- • Surplus: 250-500 calories/day above TDEE
- • Rate: 0.25-0.5 lbs (0.1-0.25 kg) per week
- • Protein: 0.7-1g per lb body weight
- • Training: Progressive resistance essential
⚡ Metabolism Boosters
- • Muscle Mass: Burns more calories at rest
- • Protein: 25-30% higher thermic effect
- • HIIT: Afterburn effect (EPOC)
- • Sleep: 7-9 hours supports metabolism
| Goal | Calorie Adjustment | Rate of Change |
|---|---|---|
| Fat Loss | -500 to -750 cal/day | 1-1.5 lbs/week |
| Maintain | TDEE (no change) | Stable weight |
| Lean Bulk | +250 to +500 cal/day | 0.5-1 lb/week |
| Aggressive Bulk | +500 to +1000 cal/day | 1-2 lbs/week |

Frequently Asked Questions
Q: How accurate is the calorie calculator?
A: Our calculator uses the Mifflin-St Jeor equation, which is considered the most accurate BMR formula available, with an accuracy rate of approximately 90%. However, individual metabolism can vary by 10-15%, so use the results as a starting point and adjust based on your actual progress over 2-3 weeks.
Q: Should I eat exactly my calculated TDEE every day?
A: Focus on weekly averages rather than daily perfection. It's normal to eat slightly more on some days and less on others. As long as your weekly average aligns with your goals, you'll see results. Daily fluctuations of 200-300 calories are perfectly fine.
Q: Why am I not losing weight at the recommended calorie deficit?
A: Several factors could be at play: 1) Inaccurate tracking (very common), 2) Metabolic adaptation after prolonged dieting, 3) Water retention from stress, sodium, or menstrual cycle, 4) Not enough time (need 2-3 weeks to see trends). If progress stalls after 3 weeks, reduce calories by another 100-200 per day.
Q: Do I need to count calories forever?
A: Not necessarily. Tracking calories is a learning tool that helps you understand portion sizes and food composition. Many people track for 2-3 months to develop intuition, then maintain their weight through mindful eating and occasional spot-checks. However, tracking can be helpful during specific goals like cutting or bulking.
