在不同人群中，体重和组成对哺乳所施加的代谢负荷的反应变化是高度可变的，在大多数报告中，哺乳期和非哺乳期妇女的体重减轻率没有差异，尽管哺乳期和非哺乳期妇女的激素环境存在差异，但在产后身体组成的变化中仅观察到细微的短期差异，在大多数研究中，哺乳期和非哺乳期妇女的脂肪沉积和动员的区域模式没有差异。哺乳期身体成分的变化是对一系列复杂的神经内分泌和生化刺激的反应，这些刺激可能会受到环境因素的显著影响，妊娠期体重增加是产后体重和脂肪量变化的最强决定因素，这支持了生物机制旨在恢复孕前体重和组成的前提。
Changes in body weight and composition in response to the metabolic load imposed by lactation are highly variable among and within diverse populations, In most reports, rates of weight loss did not differ between lactating and nonlactating women, Despite differences in the hormonal milieu between lactating and nonlactating women, only subtle short-term differences were observed in postpartum changes in body composition, Regional patterns of fat deposition and mobilization did not differ between lactating and nonlactating women in most studies, Changes in body composition during lactation are responses to a sequence of complex neuroendocrine and biochemical stimuli that may be significantly modified by environmental factors, Gestational weight gain was the strongest determinant of postpartum weight and fat mass change, which supports the premise that biological mechanisms are aimed at restoring prepregnancy body weight and composition.
