This is tautological. The recommended bandings are based on death rates and now they're saying, based on new evidence, that the bandings were wrong for certain ages. But the headline always claims being "overweight" is good for you.<p>It's like a doctor telling you to take 1 pill a day but you secretly take 4. When science decides that taking 4 a day is the correct dose it doesn't mean overdosing is good for you, it means the old dose guideline was wrong.
