Calorie Calculator
This Calorie Calculator determines your daily caloric needs based on factors like age, gender, weight, height, and activity level. It provides both basal metabolic rate (BMR) and total daily energy expenditure (TDEE) to help with weight management and nutrition planning.
Understanding Calorie Calculations
Learn about calorie needs, BMR, and how to use this calculator effectively.
Basic Concepts
- Calories are a measure of energy in food and drinks
- BMR (Basal Metabolic Rate) is the energy needed for basic life functions
- TDEE (Total Daily Energy Expenditure) includes BMR and activity level
- Weight management depends on balancing calorie intake and expenditure
Calculation Methods
- Harris-Benedict Equation: A widely used formula for BMR calculation
For men: 88.362 + (13.397 × weight) + (4.799 × height) - (5.677 × age)
For women: 447.593 + (9.247 × weight) + (3.098 × height) - (4.330 × age)
- Mifflin-St Jeor Equation: A more recent and accurate formula
For men: (10 × weight) + (6.25 × height) - (5 × age) + 5
For women: (10 × weight) + (6.25 × height) - (5 × age) - 161
- Activity Multipliers: Factors to calculate TDEE from BMR
TDEE = BMR × Activity Level Factor
Activity Levels and Multipliers
Understanding how activity affects calorie needs.
- Sedentary (little or no exercise): BMR × 1.2
- Lightly active (light exercise 1-3 days/week): BMR × 1.375
- Moderately active (moderate exercise 3-5 days/week): BMR × 1.55
- Very active (hard exercise 6-7 days/week): BMR × 1.725
- Extra active (very hard exercise & physical job): BMR × 1.9
Weight Management Goals
- Weight maintenance: Consume TDEE calories
- Weight loss: Create a deficit of 500-1000 calories/day
- Weight gain: Add 300-500 calories to TDEE
- 1 pound of fat equals approximately 3,500 calories
- Safe weight loss is typically 1-2 pounds per week
Important Considerations
- Results are estimates and may vary by individual
- Factors like muscle mass and genetics affect metabolism
- Medical conditions can impact calorie needs
- Regular exercise improves metabolic health
- Consult healthcare providers for personalized advice
- Track progress and adjust as needed
