Daily Calorie Needs Calculator

🔥 What Is the Daily Calorie Needs Calculator and How Does It Work?

The Daily Calorie Needs Calculator on AskAsklepios.com is a reliable, science-based tool that helps you estimate how many calories your body needs each day. It considers your age, sex, height, weight, activity level and goal (such as weight loss, maintenance or gain) to provide a personalized daily energy requirement in kcal/day.

Understanding your caloric needs is crucial for maintaining a healthy weight, optimizing performance and supporting overall well-being.

📊 How Is It Calculated?

The calculator first estimates your Basal Metabolic Rate (BMR) – the number of calories your body burns at rest – using established scientific formulas such as:

  • Mifflin-St Jeor Equation (widely accepted for its accuracy)
  • Harris-Benedict Equation (a classic model still used for reference)

Then, it applies a multiplier based on your physical activity level to calculate your Total Daily Energy Expenditure (TDEE) – your body’s total energy requirement per day.

Example Formula (Mifflin-St Jeor):

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

Then:

TDEE = BMR × Activity Factor

⚙️ Activity Levels You Can Choose:

  • Sedentary: Little or no exercise
  • Lightly Active: Light exercise 1–3 days/week
  • Moderately Active: Moderate exercise 3–5 days/week
  • Very Active: Hard exercise 6–7 days/week
  • Extra Active: Intense daily exercise or physical job

🎯 What Are Your Goals?

The tool also lets you choose your fitness goal:

  • Maintain Weight: Calorie intake equals your TDEE
  • Lose Weight: A calorie deficit is applied
  • Gain Weight: A calorie surplus is added

The results provide:

  • Your TDEE (Total Daily Energy Expenditure)
  • Your Target Daily Calorie Intake Based on Goal
