Ark Health Calculator

Reviewed by Calculator Editorial Team

The ARK Health Calculator helps you estimate key health metrics including Body Mass Index (BMI), Basal Metabolic Rate (BMR), and Total Daily Energy Expenditure (TDEE). These calculations provide valuable insights into your health and fitness goals.

Introduction

Understanding your health metrics is crucial for making informed decisions about your lifestyle and fitness. The ARK Health Calculator provides three essential metrics:

  • Body Mass Index (BMI): A measure of body fat based on height and weight.
  • Basal Metabolic Rate (BMR): The number of calories your body needs to perform basic functions at rest.
  • Total Daily Energy Expenditure (TDEE): The total number of calories your body burns in a day, including activity.

These metrics help you assess your weight status, estimate calorie needs, and plan your diet and exercise accordingly.

How to Use This Calculator

  1. Enter your age, gender, height, weight, and activity level in the calculator panel.
  2. Click the "Calculate" button to compute your health metrics.
  3. Review the results and interpretation provided.
  4. Use the information to make informed decisions about your health and fitness.

For the most accurate results, ensure your measurements are up-to-date and consistent with the units selected.

Formulas Used

The ARK Health Calculator uses the following formulas to calculate your health metrics:

Body Mass Index (BMI)

BMI = weight (kg) / (height (m) × height (m))

BMI is a simple index of weight-for-height that is commonly used to classify underweight, normal weight, overweight, and obesity.

Basal Metabolic Rate (BMR)

For men: BMR = 88.362 + (13.397 × weight in kg) + (4.799 × height in cm) - (5.677 × age in years) For women: BMR = 447.593 + (9.247 × weight in kg) + (3.098 × height in cm) - (4.330 × age in years)

BMR represents the number of calories your body needs to perform basic functions at rest, such as breathing, circulation, and digestion.

Total Daily Energy Expenditure (TDEE)

TDEE = BMR × activity factor

The activity factor depends on your daily activity level:

  • Sedentary (little or no exercise): 1.2
  • Lightly active (light exercise/sports 1-3 days/week): 1.375
  • Moderately active (moderate exercise/sports 3-5 days/week): 1.55
  • Very active (hard exercise/sports 6-7 days a week): 1.725
  • Extra active (very hard exercise/physical job & exercise 2x/day): 1.9

TDEE provides an estimate of the total number of calories your body burns in a day, including activity.

Interpreting Your Results

Understanding your BMI, BMR, and TDEE results can help you make informed decisions about your health and fitness.

BMI Interpretation

BMI Range Classification
Below 18.5 Underweight
18.5 - 24.9 Normal weight
25.0 - 29.9 Overweight
30.0 and above Obesity

BMR Interpretation

Your BMR represents the number of calories your body needs to perform basic functions at rest. This value is essential for estimating your daily calorie needs based on your activity level.

TDEE Interpretation

Your TDEE provides an estimate of the total number of calories your body burns in a day, including activity. This value helps you determine your daily calorie needs for weight maintenance, loss, or gain.

Worked Examples

Let's look at a practical example to understand how the ARK Health Calculator works.

Example Calculation

Consider a 30-year-old woman who is 165 cm tall, weighs 60 kg, and has a moderately active lifestyle.

Step 1: Calculate BMI

BMI = 60 kg / (1.65 m × 1.65 m) = 22.04

This BMI falls within the normal weight range (18.5 - 24.9).

Step 2: Calculate BMR

BMR = 447.593 + (9.247 × 60 kg) + (3.098 × 165 cm) - (4.330 × 30 years) = 1,300 kcal/day

This BMR represents the number of calories your body needs to perform basic functions at rest.

Step 3: Calculate TDEE

TDEE = 1,300 kcal/day × 1.55 (moderately active) = 2,015 kcal/day

This TDEE provides an estimate of the total number of calories your body burns in a day, including activity.
