Basal Metabolic Rate is a measurement of energy required to keep the body functioning at rest. Measured in calories, metabolic rates increase with exertion, stress, fear, and illness.

Your BMR will tell you the base level of calories you must consume. The BMR calculation on Naked Gym uses the Harris-Benedict formula and is based on gender, weight, height and age.

Regular Calorie Burn is the amount of calories your body burns as a result of your regular daily level of activity (excluding any additional workout activity).

For example if you have a sedentary desk job you would have a lower RCB than if you had a more physical job like a builder or sheep shearer.

Your regular level of activeness determines how many calories your body burns by going about your normal week.

Factor in your normal level of activity but DO NOT include your planned gym workouts, you will add these activities as you complete them.
