肥胖一直被认为是导致2型糖尿病的危险因素之一。但是一项最近的研究显示，如果脂肪的位置合适，它们其实有助于预防糖尿病。

堆积的脂肪

肥胖和糖尿病之间存在着密切的联系。但是Joslin糖尿病中心的研究人员们发现身体某些部位的脂肪其实可以降低糖尿素抵抗，进而保护人们远离糖尿病的威胁。

拉斯韦加斯内分泌学家Fred Toffel称，臀部、大腿以及皮肤下面的脂肪可以提高胰岛素的水平。但是，如果脂肪在肚子上堆积过多，那么在某些肌肉周围的脂肪也会相应堆积，这样的人患糖尿病的危险性会增加。

“你会发现某些病人的肌肉和心肌中存在脂肪。在这些部位存在的脂肪是非常危险的，它会妨碍身体对糖的正常利用，”Toffel博士说。

另外，他还介绍了一种新发现，即吸脂术不会对防治糖尿病产生任何帮助。

Too Much Body Fat May Affect Type 2 Diabetes Risk

Having too much body fat is believed to be a risk factor for type-2 diabetes. But new research suggests that depending on the location of the fat, it may actually be beneficial in preventing the onset of diabetes.

There are strong links between type-2 diabetes and obesity. But researchers at the Joslin Diabetes Center found that fat from some areas of the body can reduce insulin resistance, and protect people from diabetes.
Las Vegas endocrinologist, Fred Toffel says fat just below the skin, in the hips and thighs is associated with improved insulin levels.

On the other hand, people with too much belly-fat are often found to also have too much fat around certain muscles, creating a higher risk for diabetes.

"You can find people who have fat in their muscles and in their heart -- in the muscles of the heart. And that's very dangerous fat. And that prevents the body from using sugar properly," said Dr. Toffel.
He also says the new understanding reversed the belief that liposuction could help diabetes
