From Dr. Robert Lustig:
"The best way to determine whether or not you've got metabolic dysfunction or not is your waist circumference, not your weight. I tell people, the scale lies more than you do. When you stand on the scale, you're measuring four compartments at once. Bone, more is better. Muscle, more is better. Subcutaneous fat, big butt fat, if you will, turns out more is better....And the fourth compartment is the visceral, or the big belly fat. So, as far as I'm concerned, it's not about weight, it's about waist. Measuring waist circumference is probably the single-best thing you can do for yourself. It's cheap, and when you exercise, you don't lose weight, you actually gain weight because you're gaining muscle. But what you're doing is, you're making mitochondria, and you're losing that visceral fat, and that's why exercise improves health, not because of weight loss."

There have been large studies that a Waist half Height is the best predictor of long term health. That should be everyone's goal, not BMI or scale weight.
