We think of obesity as a state of excess,but it’s really more akin to a state of starvation.If the fat cells are storing too many calories,the brain doesn’t have access to enough to make sure that metabolism runs properly. So the brain makes us hungry in an attempt to solve that problem, and we overeat and feel better temporarily.But if the fat cells continue to take in too many calories, then we get stuck in this never-ending cycleof overeating and weight gain. The problem isn’t that there are too many calories in the fat cells, it’s that there’s too few in the blood stream, and cutting back on calories can’t work.
我们总认为肥胖是一种过剩，但它实际上更近似饥饿的状态。如果脂肪细胞总是过度地储存热量，大脑就得不到足够的热量来确保新陈代谢正常运行。为了解决这个问题，大脑让我们产生了饥饿感，于是我们吃下了超量的食物，暂时感觉好过了一些。但如果脂肪细胞继续囤积过多的热量，我们就会被困在无休无止的“暴饮暴食—体重增加”的循环当中。所以问题并不在于脂肪细胞中的热量过多，而是血液中的热量太少。这就是靠减少热量摄入无法成功减肥的原因。

An analogy would be like trying to treat a fever with an ice bath. Imagine going to the hospital with a very high fever,and the doctor says, “Fever is just a problem of heat balance – too much heat in the body, not enough heat leaving the body.” That’s true from a physics standpoint.So the doctor decides to put you in an ice bath. That will work temporarily. An ice bath will break your fever. But imagine what’s going to happen. Your body is going to fight back furiously with severe shivering and blood vessel constriction and you’ll feel miserable. You’ll want out of that ice bath as soon as possible. For that reason, ice baths are not a popular treatment for fever.
我们可以拿“试图用冰浴退烧”来做个类比。想像一下，你因为发高烧而去医院就诊，医生跟你说：“发烧只是热平衡的问题——体内热量过多，散热不足。”从物理学的角度来看，这倒是也没错——于是医生决定让你接受冰浴。暂时看来，这当然会有效，冰浴确实能让你的体温降低。但是，请想像一下接下来会发生什么。你的身体很快会对低温环境做出反击，你剧烈颤抖，血管收缩，你觉得苦不堪言，渴望尽快从那冰浴中逃离。所以，医生根本不会把冰浴作为退烧的常用治疗手法。

A much more effective approach is to lower the body’s temperature set point, which is done with medicine like aspirin. Put biology on your side by eating the right way, and weight loss occurs naturally as a fever would break if you treat the underlying cause of the fever.
利用阿司匹林等药物降低体温调定点是更为有效的方法。正如你想要退烧，就要治疗发烧的根本原因一样，当你食用正确的食物时，生物学规律就会自然而然地帮你减肥。
