What is Calorie Calculator?
A calorie calculator estimates the number of calories you should eat daily to reach your weight goal. It uses the Mifflin-St Jeor equation to determine your Basal Metabolic Rate (BMR), adjusts for activity level to get Total Daily Energy Expenditure (TDEE), then applies your goal (lose, maintain, or gain weight) to set a calorie target. It also provides a macronutrient breakdown showing recommended grams of protein, carbohydrates, and fat.

Frequently Asked Questions
How many calories should I eat to lose weight?
A common approach is eating 500 calories below your TDEE, which results in roughly 1 pound of fat loss per week. This calculator applies that deficit automatically when you select the weight loss goal.
How are the macros calculated?
Macros are split as 30% protein, 40% carbs, and 30% fat of your total calorie target. Protein and carbs provide 4 calories per gram, fat provides 9 calories per gram.
Is this accurate for everyone?
The Mifflin-St Jeor equation is the most validated formula for estimating calorie needs in healthy adults. Individual results may vary based on metabolism, genetics, and medical conditions.
