As people in rich countries know very well, eating too much food and burning too few calories is why a substantial number of us are overweight or obese. Now, however a remarkable change in perspective has come from the discovery that obesity actually provides people with temporary protection from the harmful effects of fat.

The insight has come from re-examming the common assumption that fatness itself drives the development of metabolic syndrome（代谢综合征）, which is what causes so much of the actual damage. The syndrome comes with a mixture of life-threatening effects, with heart disease being among the most serious. In fact, it now seems that body fat may be a barrier that stops millions of Americans and fatty citizens elsewhere from going on to develop the syndrome. And the real damage is caused by the inflammatory（发炎的）effect of high levels of fat in the bloodstream. And ironically, it is fat cells that protect us from this by serving as toxin dumps (毒素垃圾场）, locking away the real trouble-makers of the modern diet.

The problem is that this protection only lasts this long, until there is simply no more room inside the fat cells. That is when they start to break down, leading to a toxin spill（毒素溢出）into the bloodstream. This sets off an inflammatory response that causes various kinds of damage to body tissues. In this way, every extra calorie takes people closer to metabolic syndrome.

So what can we do to stop a superabundance of fat triggering the syndrome? Of course there’s no substitute for a healthy diet and exercise, but actually involving them into your daily life is hard. As with cigarettes and alcohol, a tax on calories—pricing foods by their energy content—is increasingly seen as another “level” to change behavior by making obesity too costly.

The new research may even suggest treatments to fight against metabolic syndrome, such as anti-inflammatory drugs. One promising candidate is salsalate, a drug related to aspirin, and the Joslin Diabetes Center in Boston is now considering large-scale trials.

What might be more helpful though, is simply a wider recognition that fatty and sugary foods are more directly toxic than we has assumed. Ideally, people should be as well informed about the harmful effects of what they eat as, for example, pregnant women are about drinking and smoking.

It is a relief to know that you have your fat tissue to protect you when you consume the extra burger or sweetened soda. But now you know the dangers of pushing your friendly fat cells beyond their natural limits.
