kil·o·cal·o·rie

(kcal) (kil'ō-kal'ŏr-ē)

The quantity of energy required to raise the temperature of 1 kg of water from 14.5-15.5°C; it is 1000 times the value of the small calorie.
Synonym(s): kilogram calorie, large calorie.

cal·o·rie

(kal'ŏr-ē)

A unit of heat content or energy. The amount of heat necessary to raise 1 g of water from 14.5-15.5°C (small calorie). Calorie is being replaced by joule, the SI unit equal to 0.239 calorie.

energy expenditure

the amount of energy, measured in kilocalories or kilojoules, that an individual uses in a given time. 24-h energy expenditure can be divided into three components: basal metabolic rate (BMR), energy expenditure of physical activity or thermic effect of activity (TEA), and the thermic effect of food (TEF). See also diet-induced thermogenesis, metabolic equivalent, metabolic rate.

She adds, "These factors raise the possibility that solutions required to reverse the rising prevalence of obesity must include societal reorganization, which would ultimately lead to decreased energy intake and increased energy expenditure by individuals.
