Understanding how many calories your body needs is the foundation of effective nutrition planning. Whether you want to lose weight, gain muscle, or maintain your current physique, our calorie calculator provides personalized estimates based on your unique characteristics and activity level.
Calories are units of energy that fuel everything your body does—from breathing and circulating blood to exercising and thinking. Your body burns calories constantly, even at rest (Basal Metabolic Rate or BMR). Total Daily Energy Expenditure (TDEE) adds activity calories to BMR. Consuming fewer calories than you burn creates a deficit (weight loss), while consuming more creates a surplus (weight gain). One pound of body fat equals approximately 3,500 calories.

Men: BMR = 10W + 6.25H - 5A + 5 | Women: BMR = 10W + 6.25H - 5A - 161Get calorie targets tailored to your body, not generic one-size-fits-all recommendations.
