Daily Calories Formula:
| From: | To: |
The daily calories calculation estimates your total daily energy expenditure (TDEE) by multiplying your Basal Metabolic Rate (BMR) with an activity factor. This provides an estimate of how many calories you need to maintain your current weight.
The calculator uses the formula:
Where:
Explanation: The equation accounts for your body's basic energy needs plus the additional energy required for your daily activities.
Details: Knowing your daily calorie needs is crucial for weight management, whether you want to maintain, lose, or gain weight. It helps create appropriate diet plans and ensures you're meeting your energy requirements.
Tips: Enter your BMR in kcal and select your activity level from the dropdown menu. The calculator will estimate your daily calorie needs to maintain your current weight.
Q1: What is BMR and how is it calculated?
A: Basal Metabolic Rate (BMR) is the number of calories your body needs to perform basic life-sustaining functions. It can be calculated using formulas like Mifflin-St Jeor or Harris-Benedict equations.
Q2: How accurate are activity factors?
A: Activity factors provide estimates based on general activity levels. Individual variations in metabolism and exact activity intensity can affect accuracy.
Q3: Should I use this calculation for weight loss?
A: This calculation gives maintenance calories. For weight loss, typically subtract 500 calories per day to lose about 1 pound per week.
Q4: How often should I recalculate my calorie needs?
A: Recalculate when your weight changes significantly, activity level changes, or every few months to account for metabolic adaptations.
Q5: Are there limitations to this calculation?
A: This is an estimate that doesn't account for individual metabolic differences, body composition, or specific health conditions.
