Our modern calorie calculator is designed to help you determine your Total Daily Energy Expenditure (TDEE) - the number of calories your body burns in a day based on various factors. Whether you're trying to lose weight, maintain your current physique, or build muscle, having an accurate understanding of your calorie needs is the first step toward achieving your health and fitness goals.
This calculator uses the Mifflin-St Jeor equation, which is considered one of the most accurate formulas for calculating Basal Metabolic Rate (BMR). Your BMR represents the number of calories your body needs to maintain basic physiological functions at rest. We then multiply this by your activity level factor to determine your total daily energy expenditure.
Key features of this calculator:
Remember, while this calculator provides a great starting point, individual needs may vary. For the best results, use your calculated TDEE as a baseline and adjust based on your body's response over time. Factors like genetics, sleep quality, stress levels, and metabolic health can all influence your actual calorie requirements.
