Abstract
In 14 overweight women, 24-h energy expenditure (EE) was measured in a whole-body indirect calorimeter: before weight reduction (100% diet), after 1 wk on a 4.2-MJ diet, after 8 wk on 4.2-MJ diet, after weight reduction on 100% diet. Data of two subjects were excluded. Mean body weight declined from 93.3 ± 7.4 (mean ± SD) to 83.4 ± 7.7 kg; 24-hEE decreased from 10.52 ± 0.83 MJ on the 100% diet to 9.58 ± 0.75 MJ on the 4.2-MJ diet. After 8 wk, 24-hEE had decreased by 15% of the initial 24-hEE to 8.92 ± 0.65 MJ. After refeeding (1 wk), it increased to 9.45 ± 0.75 MJ. Calculated energy requirement before weight reduction was 10.62 ± 0.88 MJ/day; after weight reduction, 9.39 ± 0.79 MJ/day. The decrease was more than that predicted from the change in body weight and body composition. An adaptation probably occurs, which may be metabolic.This publication has 14 references indexed in Scilit:
