The nutrition transition has created an obesogenic environment resulting in a growing obesity pandemic. An optimal foraging approach provides cost/benefit models of cognitive, behavioral and physiological strategies that illuminate the causes of caloric surfeit and consequent obesity in current environments of abundant food cues; easy-access and reliable food patches; low processing costs and enormous variety of energy-dense foods. Experimental and naturalistic observations demonstrate that obesogenic environments capitalize on human proclivities by displaying colorful advertising, supersizing meals, providing abundant variety, increasing convenience, and utilizing distractions that impede monitoring of food portions during consumption. The globalization of fast foods propels these trends.
营养转型创造了一种致肥胖环境，导致肥胖大流行日益严重。一种最佳觅食方法提供了认知、行为和生理策略的成本/效益模型，这些模型揭示了在当前食物线索丰富、食物获取便捷且可靠、加工成本低以及能量密集型食物种类繁多的环境中热量过剩及随之而来的肥胖的成因。实验和自然观察表明，致肥胖环境利用人类的习性，通过展示色彩鲜艳的广告、提供超大份餐食、增加种类、提高便利性以及利用干扰因素来阻碍进食时对食物分量的监控。快餐的全球化推动了这些趋势。
