Calorie Calculator - Estimate Your Daily Needs

The Calorie Calculator is a practical tool designed to help you estimate the number of calories your body needs to maintain, lose, or gain weight. It takes into account various factors such as your age, gender, weight, height, and activity level to calculate your Total Daily Energy Expenditure (TDEE). Knowing your daily caloric needs can help you make more informed decisions about your diet, whether you're trying to maintain your current weight, lose excess fat, or build muscle mass.

Here’s how a typical Calorie Calculator works:

Factors Considered:

1. Basal Metabolic Rate (BMR): The number of calories your body needs at rest to maintain essential functions like breathing and circulation.

2. Activity Level: How active you are during the day—whether you're sedentary, lightly active, moderately active, or very active—greatly influences the number of calories you burn.

3. Caloric Goal: Depending on your goals, the calculator adjusts your daily calorie intake to help you either lose, gain, or maintain weight.

Calorie Calculator Formula:

Most calculators use the Mifflin-St Jeor equation to estimate your BMR, and then multiply it by an activity factor to determine your TDEE:

Mifflin-St Jeor Equation:

• For men:

BMR = 10 × weight (kg) + 6.25 × height (cm) - 5 × age (years) + 5

•For women:

BMR = 10 × weight (kg) + 6.25 × height (cm) - 5 × age (years) - 161
