How to Use the Calorie Calculator
Enter your age, select your gender, input your height and weight in your preferred units, and choose your activity level from the dropdown. The calculator uses the Mifflin-St Jeor equation to compute your Basal Metabolic Rate (BMR) and then multiplies it by an activity factor to determine your Total Daily Energy Expenditure (TDEE). Results include calorie targets for maintaining weight, losing 0.5 or 1 pound per week, and gaining 0.5 pounds per week.
Understanding Calories and Energy Balance
Calories are a unit of energy that your body uses for everything from breathing to running marathons. Your body requires a baseline number of calories each day just to keep you alive, and any physical activity adds to that requirement. Understanding your personal calorie needs is the foundation of any effective nutrition plan, whether your goal is weight loss, maintenance, or muscle gain.
Tips for Managing Your Calorie Intake
Once you know your TDEE, you can structure your meals to hit your daily target. Focus on nutrient-dense foods like lean proteins, whole grains, fruits, and vegetables to stay full while managing calories. Track your intake for a few weeks to build awareness, then adjust your target up or down based on how your weight responds. Small, consistent changes are far more sustainable than drastic calorie cuts.
