@mara_fiorentina @RadioFreeTom @JamesRaxz It's hard do separate cause and effect. When people expect to be eating more, they'll reject restaurants that serve portions that are "too small". It is possible that less dense walkable cities in the US plays a role, Probably not whole story since obesity on the rise globally.
@马拉·佛罗伦萨@RadioFreeTom@詹姆斯·拉克斯很难区分因果关系。当人们期望吃得更多时，他们会拒绝提供“太少”的餐馆。美国人口密度较低的步行城市可能起到了一定的作用，但可能不是因为肥胖在全球呈上升趋势。
