Understanding your daily calorie needs is essential for maintaining a healthy weight, losing weight, or building muscle. Our Calorie Calculator helps you determine your Basal Metabolic Rate (BMR) and Total Daily Energy Expenditure (TDEE) using the scientifically validated Mifflin-St Jeor equation. Whether you're looking to manage your weight, optimize your nutrition, or achieve specific fitness goals, our tool provides personalized calorie estimates based on your unique characteristics.
Accurate Estimates: Our calculator uses the Mifflin-St Jeor equation, which is considered one of the most accurate formulas for estimating BMR and TDEE. This ensures you get reliable calorie estimates tailored to your body.
Comprehensive Analysis: Calculate both your BMR (the calories your body burns at rest) and TDEE (total calories burned including activity), giving you a complete picture of your daily energy needs.
Easy to Use: With a simple and intuitive interface, our Calorie Calculator makes it easy to determine your daily calorie requirements. Just input your age, gender, weight, height, and activity level, and get instant results.
Personalized Recommendations: Get calorie estimates customized to your specific body composition and activity level, helping you make informed decisions about your nutrition and fitness goals.
Basal Metabolic Rate (BMR): This is the number of calories your body burns at rest to maintain vital functions like breathing, circulation, and cell production. It represents approximately 60-75% of your total daily calorie expenditure.
Total Daily Energy Expenditure (TDEE): This is the total number of calories you burn per day, including your BMR plus calories burned through physical activity and exercise. TDEE is the number you should use when planning your diet for weight maintenance, weight loss, or muscle gain.
Weight Loss: To lose weight, consume 500-1000 calories less than your TDEE per day, aiming for a loss of 1-2 pounds per week.
Weight Maintenance: To maintain your current weight, consume calories equal to your TDEE.
Muscle Gain: To gain muscle, consume 300-500 calories more than your TDEE, combined with strength training.
Track Your Progress: Monitor your weight and adjust your calorie intake based on your results and goals.
How accurate is this calculator?
The Mifflin-St Jeor equation is considered one of the most accurate BMR formulas available, but individual results may vary. Factors like muscle mass, metabolism, and health conditions can affect your actual calorie needs.
Should I use BMR or TDEE for my diet?
Use TDEE as your starting point, as it accounts for your activity level. BMR only represents calories burned at rest and doesn't include physical activity.
How often should I recalculate my calories?
Recalculate your calorie needs when you experience significant changes in weight, activity level, or age. Many people recalculate every few months or when starting a new fitness program.
Can I use this calculator if I'm pregnant or breastfeeding?
This calculator is designed for general adult use. If you're pregnant or breastfeeding, consult with a healthcare professional for personalized calorie recommendations.
