What Fat Dogs May Tell Us About Overweight Humans

超重犬揭示关于人类肥胖那些事儿

Two bowls of food were placed in front overweight dogs,one with a more appealing meal and the other empty or containing food they did not like as much. Hungarian researchers found that normal weight dogs continue to obey instructions to look for a second bowl for food while the obese animals refused after a few rounds. The results were surprising since the researchers had expected the overweight dogs to do anything for food.

两碗食物被放在超重的狗面前,一碗是更有吸引力的食物,另一碗是空的或含有他们不喜欢的食物。匈牙利研究人员发现,正常体重的狗会继续按照指示寻找第二碗食物,而肥胖的狗则会在几轮后拒绝进食。研究结果令人惊讶,因为研究人员原本以为超重的狗会为食物做任何事。

We expected that the overweight dog would see a neutral situation positively too,that it they would expect the pot to contain food no matter how much energy required for them. The main thing is to find some food but in this test we saw the opposite. The overweight dogs took a negative view and did not expect to find food in the neutral place.

我们希望超重的狗也能在一个中立的情况中持积极心态,他们希望罐子里装着食物,不管他们需要的能量是多少。最重要的是找到一些食物,但是在这次测试中我们看到了相反的结果。超重的狗持负面看法,并没有期望在中立的地方找到食物。

This means, the researchers say that the overweight canines tried to maximize their food intake from the higher quality food and hesitated to do the task when the food reward was uncertain. Our explanation for this is that they go for the sure thing.

这意味着,研究人员说,超重的犬科动物试图最大限度地从高质量食物中摄取食物,并在食物奖励不确定时犹豫不决。我们对此的解释是,他们只对确定的情况有兴趣。

If the situation is uncertain and they cannot find food,then they are unwilling to invest energy in searching for it; for them the main thing is to find the right food with the least energy. This is where we can draw a parallel with human obesity where food rewards and a negative psychological state are behind obesity.

如果形势不确定,他们找不到食物,那么他们就不愿意投入精力去寻找食物;对他们来说,最重要的是找到能量最少的食物。这就是我们可以把人类肥胖和食物奖励以及消极的心理状态相提并论的地方。

So dogs which share our living environment may be good standings for scientists studying the causes and consequences of obesity. They have very similar social cognitive capacity to humans. So for dogs and many humans good food is a reward worth waiting for.

因此,与我们生活环境相同的狗可能是研究肥胖原因和后果的科学家们的好选择。它们与人类有非常相似的社会认知能力。所以对狗和许多人来说,美食是值得等待的奖赏。
