The stability of resting metabolic rate and diet-induced thermogenesis in children

The stability of resting metabolic rate and diet-induced thermogenesis was assessed in a group of 8- to 12-year-old children over two sessions. Children were first oriented to the laboratory and participated in a practice session to adapt them to the laboratory procedures. The two metabolic sessions began with the measurement of resting metabolic rate. The children were then provided a caloric challenge, with metabolic measures taken at 30-min intervals for 150 min. Results showed stable resting and integrated diet-induced thermogenic responses across sessions. Differences in the pattern of response from 30 to 60 min were observed, with the response peaking earlier in the first session.This experiment was supported in part by Grant HD19532 NICHD awarded to the first author.
