Document Summary
Overweight: being too heavy for one"s height (bmi is between 25 and 29. 9) Obesity: a condition characterized by excess body fat (bmi is greater than 30) Energy balance: the amount of energy consumed in the diet compared with the amount expended by the body over a given period. Bomb calorimeter: an instrument used to determine the energy content of food. It measures the heat energy released when a dried food is combusted. Bomb calorimeter values are slightly higher than the total amount of energy contained in that food because the body cannot completely digest, absorb, and utilize all the substances in that food. Triglycerides are broken down into fatty acids and glycerol. Total energy expenditure (tee): the sum of energy used for basal metabolism, activity, processing food, deposition of new tissue, and production of milk. Basal energy expenditure (bee): the energy expended to maintain an awake resting body that is not digesting food.
