大多数国家肥胖率的持续上升表明，目前旨在对抗肥胖的计划和举措在扭转肥胖流行方面并不成功。由于大多数人的体重逐渐增加，肥胖率正在上升。通过改变生活方式来治疗已形成的肥胖症几乎没有长期成功，这可能是因为保持体重所需的饮食和体育活动的巨大永久性变化。解决肥胖流行病的另一种策略是不关注减肥，而是促进饮食和体育活动的微小变化，以初步防止体重进一步增加。通过使用这一策略，肥胖率可以首先在大多数人群中稳定下来，然后随着时间的推移逐渐下降。支持数据表明，少量减少有意识的能量摄入和增加体力活动可以减少过度的体重增加。现在有机会利用小变化的方法将不同的肥胖症持有者聚集在一起，制定一项国家倡议，以解决全球肥胖症流行的问题。美国营养学会、食品技术专家研究所和国际食品信息理事会联合工作组认为，一个旨在帮助人们有意识地改变生活方式的小变化框架，与私营部门的努力相结合，逐步“减少”一些导致能量摄入过多和身体活动率下降的环境因素，可以成功降低肥胖率。这一举措将得益于在政府投入和支持下开展的教育和社会营销活动的支持。Am J Clin Nutr 2009; 89：477-84。
The continued rise in obesity rates in most countries suggests that current programs and initiatives designed to combat obesity have not been successful in reversing the obesity epidemic. Obesity rates are increasing because of a gradual weight gain in most populations. There has been little long-term success in treating established obesity through lifestyle change, perhaps because of the large permanent changes in diet and physical activity required to keep weight off. An alternative strategy to address the obesity epidemic involves not focusing on weight loss but promoting small changes in diet and physical activity to initially prevent further weight gain. With the use of this strategy, obesity rates could first be stabilized in most populations and then, over time, decrease gradually. Supporting data show that small reductions in conscious energy intake and increases in physical activity can reduce excessive weight gain. The opportunity exists to use the small-changes approach to bring different stake-holders together to create a national initiative to address the global epidemic of obesity. The Joint Task Force of the American Society for Nutrition, Institute of Food Technologists, and International Food Information Council believe that a small-changes framework, aimed at helping people make conscious small changes in lifestyle behaviors, in combination with efforts by the private sector to gradually "ratchet down" some of the environmental factors that have contributed to excessive energy intake and the declining rates of physical activity, can be successful in reducing obesity rates. Such an initiative would benefit from the support of educational and social marketing campaigns developed with governmental input and support. Am J Clin Nutr 2009; 89: 477-84.
