This news article is great news for us carrying around a few (or a lot of) extra pounds but I think the author is missing the point.
But the scientists also found that people classified as overweight, with a BMI of 25 to 29.9, died at slightly lower rates — not higher — than those of so-called normal weight. And they found that those who were mildly obese, with a BMI of 30 to 34.9, died in no greater numbers than did their normal-weight peers.
From what I’m reading those people classified as overweight might ought to be reclassified as normal while those currently classified as normal weight should probably be classified as underweight and those with a BMI of between 30 to 34.9 or just obese should be reclassified as overweight. I say this because the overweight group is actually living longer lives.
