Resting Calories
Your resting calories per day is the amount of energy (in the form of calories) that your body needs to function while resting. This is also known as BMR, or Basal Metabolic Rate. This number of calories reflects how much energy your body requires to support vital body functions. In fact, your BMR is the single largest component (upwards of 60 percent) of your total energy burned each day.
Basically, your body burns calories just by doing nothing, and this is the number those calories are.
Active Calories
These are the calories you burn by being active, such as walking, hiking, playing sports, etc. These calories are vital to losing weight, as the only way to burn more calories than you eat while maintaining a healthy diet is to burn active calories.
Total Calories
This is the sum of the Resting Calories and Active Calories you burn in a 24 hours. This is the number of calories you should be focusing on each day when factoring in how many you burned. Combining both Active Calories and Resting Calories gives you the most complete picture of your day.
