In your post, you mention the Kramer et al. article recently published in Annals in Internal Medicine. It is important to note that this study had some major limitations. Most notably, they did not account for fitness, nutrition, or any of the many factors that typically mediate the relationship between weight and health. So they did not really examine whether it is possible to be "fat and fit." Recent other research has shown that physical fitness is a far better predictor of health outcomes than BMI. I recently tackled this issue in my PT blog post titled "Don't Believe Everything Your Read"
