In contrast to the undefined term "light" energy-reduced food is defined by the Swiss law that the energy-content has to be reduced by 30%, and energy-poor corresponds to a reduction of at least 50%, respectively. This must not be achieved by a reduction in protein content. Energy- and fat-reduced products are widely used; especially the use of low-fat dairy products is recommended by US guidelines as part of a healthy lifestyle pattern. There is evidence that such a lifestyle can positively influence the course and incidence of several chronic diseases like type 2 diabetes, arterial hypertension and atherosclerotic complications. However, the consumption of light products alone has not been shown to be associated with health benefits, in particular not with reduced body weight.
与未明确界定的“低热量”食品不同，瑞士法律对能量降低型食品进行了定义，即其能量含量必须降低30%，而低能量食品则分别对应至少降低50%。这不能通过降低蛋白质含量来实现。能量和脂肪降低型产品被广泛使用；特别是美国指南推荐将低脂乳制品的使用作为健康生活方式的一部分。有证据表明，这种生活方式可对2型糖尿病、动脉高血压和动脉粥样硬化并发症等几种慢性病的病程和发病率产生积极影响。然而，单独食用低热量产品并未显示与健康益处相关，尤其与体重减轻无关。
