Scientists say that certain genes disrupt the messages the stomach sends to the brain saying it is full, meaning the cravers always feel like they need more fatty, sugary food.

科学家们说，某些基因会破坏胃向大脑发送的信息，表示它已经饱了，这意味着渴望者总是觉得他们需要更多的脂肪和含糖食物。

During the study, people from all three groups lost weight on the tailored diets, with feasters losing the most and constant cravers losing the least.

在研究期间， 所有三组人都通过量身定制的饮食减轻了体重，食客减重最多， 渴望者减重最少。
