A condition characterized by a body mass index of 30 or more

Obesity

Body weight minus fat storage weight

Lean body mass

Altering the environment to minimize the stimuli for eating-for example, removing foods from sight

Stimulus control

Minimal energy the body requires to support itself when resting and awake

Basal metabolism

A method of determining a body's energy use by measuring heat that emanates from the body

Direct calorimetry

A method of measuring a body's energy use by measuring its oxygen uptake and then using formulas to convert that gas exchange into energy use

Indirect calorimetry

Metabolism that characteristically conserves more energy than normal so that it increases the risk of weight gain and obesity

Thrifty metabolism

Breaking the link between two or more behaviors that encourage overeating, such as snacking while watching television

Chain breaking
