So they basically added metabolic impairment and visceral fat to the definition of obesity. That is going to confuse alot of people. I really don't see the benefit of putting all the metabolic problems under the label of obesity other then attention grabbing. It would be much more helpful to classify these as symptoms of hyperinsulinemia.... the real problem.
Fat people have 'excess adiposity' and people with broken metabolisms have 'clinical obesity'....
