Focusing excessively on being overweight as its own risk factor for mortality, independent of biomarkers or metabolic health, does not seem warranted.

I 'll quote this from the article for emphasis. The obesity range tho, is not challenged as far as health consequences go. While treating both ranges as if they are same is probably wrong, one doesn't get obese without being overweight first. As for the excessive part, I laughed at the percentages :-)

As for the overweight part, in my experience, when it comes to my heart, whether it is just extra fat or extra muscle, it's still extra weight to carry. Life is much easier without it. Beyond a point, I need a really good reason to maintain extra weight even if it is just muscle tissue and vanity is not even a bad one.
