You can be overweight, and heck even obese and still be healthy, yes if you're very obese, it's probably not good for you, but just being overweight doesn't mean you're unhealthy. There are fatter people who eat well and exercise and thin people who do neither. It depends on the person, all I'm saying.
I don't like the terms overweight and underweight anyway. Under and Over WHO's Weight?
Sorry, but weight misinformation is one of the things that gets my goat.
