The studies that have looked at the effects of low or restricted energy intakes on the activity of infants and children, although small in number, coincide in that reduced intake leads to shorter duration or lower intensity of physical activity. This occurs within a few days after dietary energy decreases VITERI and TORUN, 1981). Initially, it seems to be a compensatory response to maintain energy balance without comprising growth. But if the dietary restriction is large enough, the decrease in activity and overall energy expenditure is not sufficient to preserve growth (TORUN and VITERI, 1981a).
