Calorie Equation:
From: | To: |
The calorie equation calculates total daily energy needs by combining basal metabolic rate (BMR) with activity calories. BMR represents calories burned at rest, while activity calories account for physical movement and exercise.
The calculator uses the calorie equation:
Where:
Explanation: The equation provides a simple way to estimate total daily calorie needs by combining resting and active energy expenditure.
Details: Accurate calorie estimation is crucial for weight management, athletic performance, and nutritional planning.
Tips: Enter BMR and activity calories in kcal/day. Both values must be positive numbers.
Q1: How do I determine my BMR?
A: BMR can be estimated using equations like Harris-Benedict or Mifflin-St Jeor, or measured via indirect calorimetry.
Q2: What's a typical activity calorie range?
A: Sedentary: 200-400 kcal/day, Moderate: 400-600 kcal/day, Active: 600-1000+ kcal/day.
Q3: Should I adjust these values over time?
A: Yes, recalculate periodically as weight, activity levels, and metabolism change.
Q4: Are there limitations to this equation?
A: It doesn't account for thermic effect of food or adaptive thermogenesis.
Q5: How precise should these numbers be?
A: These are estimates. Individual needs may vary by ±10-20%.
