Weight being mostly of muscle is different than mostly of fat. When we say obese, it's the later one.
Really?
Would you mind telling that to my former doctor who wrote down in my chart that I was “obese” just based on my height, weight, and a quick visual scan? She was starting into “substantial lifestyle change” talks before I showed her my data.
She didn’t reverse course until I showed her my dexa scan and told her my diet and exercise regimen.
My point is that there are plenty of people who are labeled a category or two worse than they actually are. Yes, many people are actually obese — I get that — but people who are naturally muscular quickly grow tired of (and sometimes numb to) being categorized as worse than they actually are.
Folks who talk about obesity, especially medical folks and media folks, would do well to be more nuanced in their analysis and discussion of the data.
