AMR (Active Metabolic Rate) Calculator









Male AMR: calories

Female AMR: calories

 

Introduction

An AMR (Active Metabolic Rate) calculator is a useful tool to estimate the number of calories an individual needs to maintain their current weight based on their activity level. In this article, we will guide you on creating an AMR calculator using HTML and JavaScript, allowing you to input weight, height, age, and activity level to calculate Male and Female AMR values.

How to Use

To use the AMR calculator, follow these steps:

  1. Input your weight in pounds.
  2. Input your height in inches.
  3. Enter your age in years.
  4. Choose your activity level from the provided options.
  5. Click the “Calculate AMR” button.

The calculator will then provide you with both the Male and Female AMR values based on the input data.

Formula

The formula for calculating AMR (Active Metabolic Rate) is as follows:

AMR = BMR * AF

Where:

  • AMR is the Active Metabolic Rate we want to calculate.
  • BMR stands for Basal Metabolic Rate, which is the number of calories your body needs at rest.
  • AF represents the Activity Factor, which depends on your chosen activity level.

Example

Suppose a 30-year-old male with a weight of 180 lbs, a height of 72 inches, and a moderate activity level wants to calculate his AMR.

Using the formula:

  1. Calculate BMR:
BMR = 66 + (6.23 * weight in lbs) + (12.7 * height in inches) – (6.8 * age in years) = 66 + (6.23 * 180) + (12.7 * 72) – (6.8 * 30) = 66 + 1121.4 + 914.4 – 204 = 1897.8 calories
  1. Choose an appropriate Activity Factor (AF). For moderate activity, we’ll use AF = 1.55.
  2. Calculate AMR:
AMR = BMR * AF = 1897.8 * 1.55 = 2940.39 calories

The AMR for this individual is approximately 2940.39 calories.

FAQs

1. What is BMR?

BMR (Basal Metabolic Rate) is the number of calories your body needs at rest to maintain basic functions like breathing and cell production.

2. How do I choose the right activity level?

You can select your activity level based on your daily routine. If you’re not sure, it’s better to underestimate your activity level to avoid overestimating your AMR.

3. Can I use metric units (kilograms and centimeters) instead of pounds and inches?

Yes, you can, but you’ll need to adjust the formula accordingly for metric units. The provided example uses imperial units.

Conclusion

Creating an AMR calculator using HTML and JavaScript allows you to estimate your daily calorie needs based on your activity level. By following the simple steps and understanding the formula, you can make informed decisions about your daily calorie intake, which can be helpful for maintaining or adjusting your weight. Feel free to customize the calculator for your website or personal use to make health and fitness planning easier.
