Document Summary
Energy balance: the amount of energy consumed in the diet compared with the amount expended by the body over a given period. Appetite: a desire to consume speci c foods that is independent of hunger: triggered by external cues such as the sight or smell of a food. Americans are more overweight than ever before: eating more and burning fewer calories. Portion sizes have increased: social changes. An increase in the number of single-parent households and households with two working parents. Fewer american adults today work in jobs that require physical labor. People drive to work rather than bike or walk, take elevators instead of stairs, use dryers rather than hang clothes outside, and cut the lawn with riding mowers rather than with push mowers. Less active during their leisure time because busy schedules and long days at work and commuting leave little time for active recreation: instead, people tend to sit in front of electronics.
