11. This has been known for years

There have been studies going back a decade that found this. This one is from 2011.

We found that 29% of subjects classified as lean and 80% of individuals classified as overweight according to BMI had a BF% within the obesity range.

The primary reason is that people who score as a "healthy weight" on the BMI scale, and don't appear obese, are in reality severely under-muscled due to lack of physical activity.

It's ironic that people have been claiming that BMI isn't accurate for years. When more accurate measurements are included that show that BMI actually underestimates obesity, that too is rejected. It's almost like a sizeable portion of the population just wants to ignore the serious health effects of obesity because it's uncomfortable to address.
