Figures and trends of the overweight epidemic

overweight
Remark: This post has been modified. You find the original version here, plus an update that tells you why I have changed my view.

In these days two thirds of all US adults are overweight or obese, according to a new review from the Johns Hopkins Bloomberg School of Public Health, Baltimore, MD. There is a steady annual increase in affected people, ranging from 0.3 to 0.9 percentage points, depending on subgroups. Minorities and people of low income are particularly at risk. By 2015, 75 percent of US adults will be overweight or obese, and 41 percent will be obese. This trend is alarming, the experts say. I have nothing to add.

According to public health experts, the border to overweight is crossed at a body mass index (BMI) of 25, and obesity is defined as a BMI beyond 30.

Update (August 31, 2007)
I do not longer share this view. It is not proven that body fat is a major source of diseases, and I'll no longer use terms like "obesity epidemic" in this blog, which assumes that obesity in itself is a disease that must be treated.
