How To Calculate Your Energy Expenditure

Calculating your energy expenditure is not only an essential means of  hitting your target race weight but is a key means of ensuring that you are taking in enough calories, as explained in the Pacific Health booklet (which you can download using the link below):

Nutrition for fuelling and recovery is largely a function of energy expenditure. Energy expenditure is a function of four parameters:

1. Total time of exercise
2. Intensity (i.e., pace)
3. Weight (heavier people burn more calories than lighter people doing the identical exercise for the identical time)
4. Exercise activity

Although you do not have to be precise, it is always good to know your overall energy expenditure. It is easy to compute. Use the table below and plug it into the following equation:

Total energy expenditure = energy expenditure value of activity x duration of activity in minutes x your body weight in pounds

For example, suppose you weigh 150 lbs and you run at a pace of 7 minutes per mile for 30 minutes. The energy expenditure value of running at 7 minutes per mile is 0.10 cal/lb/min. Therefore, the total energy cost of the workout is 0.10 x 150 x 30 = 450 calories.
