summary：A new research tells us that it may be good to someone with a five to ten overweight when it comes to certain cancers and heart disease. Besides, researchers also found that the men who are overweight may also be protected from other diseases not commonly associated with excess weight. However, it also tells that people who are more than fifteen kilos above their ideal weight will die very easily due to a variety of illnesses. Therefore, according to Dr. Flegal, we should still take care of our own bodies not to be too overly overweight.
