Effects of rapid weight loss and regain on body composition and energy expenditure.

摘要: Weight-classified athletes need an energy intake plan to accomplish target weight reduction. They have consider body composition and metabolism during rapid loss followed by regain achieve their plan. We investigated the effects of loss, regain, on expenditure. Ten weight-classified were instructed reduce 5% in 7 days. Following they asked try all lost with ad libitum diet for 12 h. Food was recorded baseline, periods. Fat mass, total water, fat-free dry solids estimated underwater weighing stable isotope dilution methods. A three-component model calculated using Siri's equation. Basal sleeping metabolic rates measured indirect calorimetry. Body expenditure before after regain. weight, decreased period but recovered (p < 0.05). rate did not change throughout study. Sleeping significantly Changes water greatly affect In addition, basal athletes.
