Obesity: A Game of Inches
Keyword(s):
Obesity, like baseball, is a game of inches. Weight gain cannot occur unless energy intake exceeds energy expenditure. Such positive energy balance is a sine qua non for normal growth in the child, and for obesity in the adult. Very small excesses of intake over expenditure can make a big difference if present over a long period of time. Consider the children in the study reported by Klesges et al1 elsewhere in this journal (pages 126-130). At about 4½ years of age, these children were estimated (by diet history) to have been ingesting about 2000 kcal per day. This is almost certainly an overestimate of the actual caloric intake of these children (see below).
