　　One of the experts who takes issue with Flegal's conclusions is Walter Willett of the Harvard School of Public Health. He's read her new paper and says he's not buying it.This study is really a pile of rubbish and no one should _1_ their time reading it.

　　Willet says it's not helpful to look simply at how peoples BMI's or body mass index influence their _2_ , as this paper did, without knowing something about people's health or fitness. Some people are thin because they're ill, so, of course they're at higher risk of dying.

　　The study doesn't tease this apart.Also, he says the analysis does not _3_ the bigger, more important issues of quality of life. If an overweight person does live longer, is he or she living with chronic diseases?

　　We have a _4_ other literature showing that people are gain weight or are overweight, have increased risk of diabetes, stroke, heart,stroke, many cancers, and many other conditions.

　　Willett says for listeners _5_ who want to know whether their body weight is a problem, one thing to do - rather than comparing your BMIto those around you - is to think about what you weighed when you were 20 years old.

　　For most people, our ideal weight - if we weren't seriously overweight at age 20 - is about what we weighed then. And that's why weight change is a good number to _6_ , because it can be an early warning sign.That you're on the path to more weight gain.

　　Now, not everyone's convinced the new paper is rubbish. Dr. Steven Hymsfield, of the Pennington Biomedical Research Center in Baton Rouge, says there are a couple of scenarios in which extra body weight might help people live longer.If you _7_ vulnerable bone, like the hip, that having a little extra fat there might protect you from hip fracture.

　　Or, he says, if an illness leaves you _8_ eat, extra body fat could be useful. Hymsfield acknowledges this is just speculation. He says while this paper won't end the debate over whether a little extra body fat could be a good thing, he says it does show that the relationship between weight and health may be more complicated than just a simple calculation.
