Role of Energy Excretion in Human Body Weight Regulation

Abstract

Food intake and energy expenditure are the typical determinants of body weight. Yet, recent observations underscore that a third and often-neglected factor, fecal energy loss, can influence energy balance. Here, we explore how macronutrient excretion modulates human energy homeostasis and highlight its potential impact on the propensity to gain weight.
