Acai Berry Bio - Lose Weight Fast with Acai Berry

This calculator gives you an estimate of the number of calories burned for a wide range of activities, however these estimates are based on the findings of experiments that generalize accross people. Enter your weight and the duration of exercise, click the calculate button and the calculator will calculate the calories burned. A given individuals energy expenditure may vary from that shown due to the persons individual characteristics as well as the intensity of your exercise.

The calculations are based on the activities Metabolic Equivalent (MET). This is an estimate of how much energy an activity burns as a multiple of an individuals resting metabolic rate (RMR). One MET is considered the energy energy expended at rest, while an exercise that was, say, 5 METs would expend approximately 5 times the energy than in a resting state. For an estimate of the number of calories you burn a day based on your BMR and your general activity level, see our more general calorie calculator.

It is common to use METs to estimate an individuals energy consumption during an activity through the equation:

Calories expended (kcal) = METs x (Weight in Kg) x (Duration in Hours).

The calculator allows you to total the energy expended during a number of activities. Click the "Add to Total" link next to the exercise once the calories have be computed. This will add this exercise to a list of exercises at the top to be added to a total calorie expenditure and the total calories of your added activities as well as their total duration will be displayed. You can also remove exercises from your total once added.

When using this calculator, it is important not to add the calories here to your Basal Metabolic Rate (BMR) or the related estimate of the number of calories you burn a day from our calorie calculator, as the energy expenditure here includes your resting metabolic rate for the duration of the exercise.
