Lab 13c Information Determining Your Daily Energy Expenditure
Estimate your basal metabolism.
First determine the number of minutes you sleep.
Monitor your activity expenditure for 1 day. Record the number of 5-, 15-, and 30-minute blocks of time you perform each of the different types of physical activities (e.g., if an activity lasted 20 minutes, you would use one 15-minute block and one 5-minute block). Be sure to distinguish between moderate (Mod) and vigorous (Vig) intensity in your logging.
Discuss your daily caloric expenditure. In addition, comment on whether you think you should modify your daily caloric expenditure for any reason.
