Introducing the concept of memory utility, we explore the effect of memory capacity on overweight and weight control by building a theoretical model and conducting related empirical research with a double-hurdle model. The result shows that better memory capacity can lead to a higher probability of overweight due to the higher discount rate and more food consumption when this person is not obese; while it helps the overweight individuals to lose weight due to memory disutility from obesity. The different effects of memory result from the tradeoff between memory utility from food consumption and memory disutility from obesity.

记忆功能，食物消耗和肥胖

在介绍记忆效用的概念时，我们通过建立理论模型并使用双关卡模型进行相关的经验研究，探索了记忆容量对超重和体重控制的影响。结果表明，更好的记忆能力可导致较高的超重概率，这是由于该人不肥胖时较高的贴现率和更多的食物消耗。同时它可以帮助超重的人减肥，因为肥胖导致的记忆丧失。记忆的不同影响是由于食用食物带来的记忆效用与肥胖引起的记忆丧失效用之间的折衷。
