What is Active Metabolic Rate (AMR)?
Your Active Metabolic Rate (AMR), also known as Total Daily Energy Expenditure (TDEE), is the total number of calories your body burns in a 24-hour period. This calculation takes into account your Basal Metabolic Rate (BMR) – the calories your body burns at rest to maintain basic functions – and adds to it the calories burned through all your physical activities and the thermic effect of food.
Understanding the Activity Levels:
- Sedentary: Minimal physical activity. This includes desk jobs and very little to no structured exercise.
- Lightly Active: Light exercise or sports 1-3 days per week. This might include walking, light jogging, or yoga sessions.
- Moderately Active: Moderate exercise or sports 3-5 days per week. This could involve more intense workouts, team sports, or regular gym visits.
- Very Active: Hard exercise or sports 6-7 days a week. This level typically involves frequent, vigorous training sessions.
- Extra Active: Very hard exercise or sports and a physical job, or training twice a day. This is for individuals with extremely demanding physical lifestyles.
By understanding your AMR, you can better manage your calorie intake for weight management, whether your goal is to lose, maintain, or gain weight. This calculator provides an estimate based on your provided BMR and chosen activity level.
function calculateAMR() {
var bmr = parseFloat(document.getElementById("bmr").value);
var activityLevel = parseFloat(document.getElementById("activityLevel").value);
if (isNaN(bmr) || bmr <= 0 || isNaN(activityLevel)) {
document.getElementById("result").innerHTML = "Please enter a valid BMR and select an activity level.";
return;
}
var amr = bmr * activityLevel;
document.getElementById("result").innerHTML = "Your estimated Active Metabolic Rate (AMR) is:
" + amr.toFixed(2) + " kcal/day";
