title: Effects of a nonenergy fat substitute on children's energy and macronutrient intake.
abstract: To determine whether children adjusted their energy intake in response to covert manipulations in the proportion of energy from dietary fat, 24-h food intake of 29 2- to 5-y-old children was measured over four 2-d blocks. In this within-subject crossover design, in the first three meals of the first day of each block, children consumed foods containing dietary fat or a nonenergy fat substitute, which provided 10% of total daily energy intake. Children compensated for the missing energy; cumulative energy intake differed by only 100 kJ over 2 d. Substitution for dietary fat reduced the percent of energy from fat from 38.7% to 36.4%. Children's intake at individual meals was highly variable (mean CV 24.7%) relative to the variability of total daily energy intake (CV = 8.6%). To produce this pattern, children adjusted energy intake across successive meals. Use of a fat substitute at 10% of energy from dietary fat did not significantly reduce 24-h energy intake.
