## Quick Answer

Calculate exactly how many calories you should eat per day to lose weight, gain muscle, or maintain your current weight based on your age, size, and activity level.

## Definition

A calorie calculator is a nutritional tool that estimates the daily caloric intake required for a person to maintain, lose, or gain weight. It first calculates the Total Daily Energy Expenditure (TDEE) using metabolic formulas like the Mifflin-St Jeor equation, then applies a caloric deficit or surplus based on the user's weight management goals. It is the foundational tool for modern macronutrient and calorie-tracking diets.

## How to Use

1. **Enter your profile** — Input your age, gender, height, and weight.
2. **Select your activity level** — Choose your baseline daily activity level from sedentary to extremely active.
3. **Choose your goal** — Select whether you want to lose weight, maintain weight, or gain muscle.
4. **Read your calorie target** — View your customized daily caloric intake target to achieve your specific goal.
