Basal Metabolic Rate
The human body converts internal chemical energy into work and heat at rates of 60 to 125 W (called the basal metabolic rate). This energy comes from the food we eat and is usually measured in kilocalories = 4.184 kJ. (Note that the nutritional calorie listed on the cereal box actually equals 1 kilocalorie). How many kilocalories of food energy must we ingest per day if our metabolic rate is 95.0 W? Assume our body is 100 percent efficient.
