英文文献摘要：
Although individuals with poor food security might be expected to have reduced food intake, and therefore a lower likelihood of being overweight, some empirical evidence has indicated that overweight status is actually more prevalent among the food insecure. As obesity is associated with excessive energy intake, and hunger reflects an inadequate food supply, such observations would appear to be paradoxical. We develop an economic model that shows that this apparently paradoxical result is consistent with rational behavior regarding food availability risk and the effectiveness of food storage options. The amount of internal storage increases as the variance of food productivity in the second period increases, which is consistent with the empirical observation of a positive relationship between food insecurity and the incidence of overweight.

虽然食品安全不佳的人可能会减少食物摄入量，因此超重的可能性较低，但一些经验证据表明，超重实际上在食品不安全人群中更为普遍。由于肥胖与能量摄入过多有关，而饥饿则反映了食物供应不足，这样的观察结果似乎是自相矛盾的。我们开发了一个经济模型，表明这个看似矛盾的结果与关于食物可用性风险和食物储存选择有效性的理性行为是一致的。在第二阶段，内部储存量随着粮食生产率的方差增加而增加，这与粮食不安全与超重发生率呈正相关的经验观察结果一致。
