[Changes in body composition in obese patients on a low-calorie diet].
Energy balance was studied on 4 obese hospitalized subjects kept on hypocaloric diet (489 Kcal - 54% CHO, 10,6% Fat, 35,4% Protein) for 18 +/- 3,7 days. Energy expenditure was measured trough heart-rate monitoring (individual calibrations before and after the study were performed) and nitrogen balance was computed to establish protein loss. Individual qualitative composition of body weight loss was then assessed: 71,4 +/- 5,23% could be attributable to fat loss, 9,38 +/- 3,32% to protein loss, 18,2 +/- 5,5% to water loss. Part of this last figure could be attributable to a slight under-estimation of the method utilized to measure the energy expenditure (heart-rate monitoring).
