Use this tool for a personalised estimate of how much energy you’re using based on the activities you do.
The amount of energy you use depends on what activity you’re doing, how intense the activity is, how long you do it for and your weight. By knowing roughly the amount of energy you’re using to do different activities, you may be able to increase your activity level or reduce your energy intake to help you reach and maintain a healthy weight.
Enter your weight in kilograms (kg). Then select a type of activity from the drop down menu and enter in how long (in minutes) you did this activity. Click ‘Calculate’ for an estimation of how much energy you would’ve used in carrying out this activity, in Calories* and in kilojoules.
