人们普遍认为，美国正处于肥胖症大流行之中(1，2)。大量的研究旨在了解这种情况是如何发生的以及为什么会发生，并找出预防和治疗肥胖的有效方法。体重的任何变化都需要永久性的行为改变，但所需的行为改变的程度因预期结果而异。“能量差距”这个术语是用来估计个人和人群达到不同体重结果所需的能量摄入和能量消耗行为的变化(3)。自从最初关于能量差距的文章发表以来，这个术语已经被对预防体重增加和治疗肥胖感兴趣的研究人员广泛使用(和误用)(3-14)。有人认为，能量差距没有考虑到能量储存随着体重增加而持续增加，因此肥胖和非肥胖个体之间随着时间的推移存在累积的能量差距，因此饮食和体力活动的微小变化不足以扭转肥胖症的流行(13，14)。这篇评论的目的是更准确地澄清能源缺口(或能源缺口)的概念，并讨论如何将这一概念恰当地用作帮助理解和解决肥胖问题的工具。
It is widely accepted that America is in the midst of an obesity pandemic (1, 2). Substantial research is directed toward both understanding how and why this has occurred and toward identifying effective ways to prevent and treat obesity. Permanent behavior change is required for any change in body weight, but the extent of behavior change needed varies with the desired outcome. The term “energy gap” was coined to estimate the change in energy intake and energy expenditure behaviors required to achieve different body weight outcomes in individuals and populations (3). Since the original article about the energy gap, the term has become widely used (and misused) by researchers interested in both prevention of weight gain and treatment of obesity (3-14). It has been argued that the energy gap fails to consider that energy stores continue to increase with weight gain so that there is a cumulative energy gap that builds over time between obese and non-obese individuals so that small changes in eating and physical activity would be insufficient to reverse the obesity pandemic (13, 14). The purpose of this commentary is to more precisely clarify the concept of the energy gap (or energy gaps) and discuss how the concept can be properly used as a tool to help understand and address obesity.
