title: Relation of specific dynamic action of food (SDA) to growth in rats.
abstract: The relation between food induced thermogenesis and anabolic processes was investigated in normal and malnourished rats. The metabolic rate was measured 5 and 17 hr after food removal. The difference between the two measurements was 3.9% during growth arrest of malnourished rats gaining 0.6 g/day, but 20.0 and 28.7% during growth recovery when rats were gaining 4.1 and 5.3 g/day, respectively. The 5 hr postprandial metabolic rates rose in normal rats from 15.6 kcal/day at 4 weeks to 45.3 kcal/day at 15 weeks, and then declined to 38.5 kcal/day at 36 weeks. The difference between 5 and 17 hr postprandial metabolic rates was 28.8% in 5 to 15-week-old rats gaining 5.2 g/day, and 1.1% in 24 to 32-week-old rats who were no longer gaining weight.
