To compare and contrast 1) changes in body composition, kinetics of major energy-yielding substrate metabolism in men and women, under resting conditions and during and following moderate exercise, during a three-week period of hypocaloric feeding. 2) kinetic and metabolic studies will include feasible and novel 24-hour stable isotope tracer-indirect calorimetry protocols, 3) explore the parameters outlined above under conditions of a balanced reduction in energy intake in comparison with a high protein/energy (lipid) dense hypocaloric diet in women and men.

比较和对比1）身体成分的变化，在静止条件下以及中度运动期间和之后，在三周的低平衡喂养期间，男性和女性的主要能量赋予底物代谢的动力学。 2）动力学和代谢研究将包括可行和新型的24小时稳定的同位素示踪剂量热法，3）在与高蛋白/能量（Lipid）密集的低钙饮食中的高蛋白/能量相比，女性和男性的高蛋白/能量（Lipid）密集的低钙饮食相比，能量摄入量平衡的条件下，探索上述参数。
