Big Stuff  
I'm currently teaching a nutrition class, and the various topics for Friday include metabolism, energy balance, weight management, and eating disorders (whew! this'll spill over into later classes, too, I'm sure).  As a contrast to all of the material that I expect the students will come up with (but they are also likely to surprise me) I'd like to have some information on being healthy while having a much larger than "acceptable" BMI. 

I know some of you out there know much more about this than I do (I know next to nothing), so I'm hoping I can get a few pointers.  Web sights?  Actual scientific studies?  Do we, for example, have actual evidence that carrying many extra pounds causes cardiac problems, or do we only have a correlation?  If only a correlation, do we have evidence that the correlation is still strong when other correlating factors (e.g., amount of trans fats in the diet) are taken out of the equation?

I'm sure others have more actual data for ya, but I just thought I'd toss this into the mix.

When the BMI first came out, I remember an article (sorry--no idea where I saw it) that looked at the U.S. Women's Crew Team and how every single one of them was classifiable as "obese" or "morbidly obese" based solely on their BMI. Granted, their weight was from muscle mass, not fat, but no one could say they were out of shape and therefore more prone to the common diseases attributed to actual obesity.

It gave me very little confidence in the BMI from that point on, I must say.
