Bob, there are a LOT of medical journals. If they have different figures I have no idea how to figure out who's right and who's wrong.
There probably isn't a definite number in reality. I think people can be underweight with different BMI's. It all depends on body composition. I'm guessing they figure out what underweight is by figuring out at what BMI people have increased health problems or something. There's probably some magical cut off figure between healthy and unhealthy. Maybe it's based on % mortality, who know?
If I have free time and I feel like it I will do some research on this.
