This tool calculates your daily calorie needs based on your activity level.
About the AMR Calculator
The AMR (Active Metabolic Rate) calculator estimates the number of calories you need per day to maintain your current weight, based on your age, gender, weight, height, and activity level. Here’s how to use it:
How to use it:
- Enter your age in years.
- Select your gender.
- Enter your weight in kilograms.
- Enter your height in centimeters.
- Select your activity level from the dropdown menu.
- Click the “Calculate” button to estimate your daily calorie needs.
How it calculates the results:
The calculator first computes your Basal Metabolic Rate (BMR) using the Mifflin-St Jeor Equation, which is different for males and females:
- For males: BMR = (10 * weight) + (6.25 * height) – (5 * age) + 5
- For females: BMR = (10 * weight) + (6.25 * height) – (5 * age) – 161
Then, it multiplies your BMR by an activity factor that corresponds to your activity level to estimate your Active Metabolic Rate (AMR):
- Sedentary (little or no exercise): AMR = BMR * 1.2
- Lightly active (light exercise/sports 1-3 days/week): AMR = BMR * 1.375
- Moderately active (moderate exercise/sports 3-5 days/week): AMR = BMR * 1.55
- Very active (hard exercise/sports 6-7 days a week): AMR = BMR * 1.725
- Super active (very hard exercise/sports & physical job or 2x training): AMR = BMR * 1.9
Limitations:
While this calculator provides a good estimate of your daily calorie needs, it has some limitations:
- It does not account for muscle mass, body composition, or metabolic variations.
- It may not be accurate for pregnant or breastfeeding women.
- It is intended for general purposes and may not be appropriate for individuals with specific health conditions.
For personalized advice, please consult a healthcare professional or a registered dietitian.
