This statement will make you (and me) confuse. New research shows that people who carry a few extra pounds tended to live longer than normal weight people. The studies including a combined of 2.88 million people.
“It is possible that under certain circumstances, being a little overweight is good as opposed to bad,” says Steven B. Heymsfield, MD, executive director of the Pennington Biomedical Research Center in Baton Rouge, La. Heymsfield
In US about 30% women and 40% men in the US are overweight based on their body mass index (BMI), a measure of size that takes into account a person’s height and weight. The review published in the Journal of the American Medical Association took about 2 decades of research into the relationship between body weight and death risk.
People with BMIs under 30 but above normall were less likely to die during the studies compared to people with normal BMIs. A reduction in the risk of death from all causes was about 6% lower for people who were overweight and it was remarkably consisten from study to study.
Though the findings are provocative, they come with some important caveats. The study only looked at the association between death and body size but didn’t include other measures of health that may be related to weight. It also doesn’t prove that body weight could make bigger people tended to live longer.

Even there’s a study but don’t make assumption that extra weight could give you long life. Maybe it is coincidence but how life that the extra weight people live? Is it healthy or bad? In my opinion, it is better to get a normal BMI and get a healthy lifestyle. It is not good to live longer but with the bad condition.
