Obesity is strongly associated with metabolic alterations and negative health outcomes including diabetes, cardiovascular disease, and some types of cancer (1, 2, 3, 4). Excess body fat is one of the primary causes of preventable health problems and mortality in the United States and many other affluent nations, ranking in importance with cigarette smoking and physical inactivity. Obesity is thought to contribute to disease via the metabolic disturbances it causes, including excess glucose and lipids in the circulation, dysregulated hormone activity including insulin and leptin, and inflammatory effects. This immediately raises two questions:

1. Does metabolically healthy obesity exist?
2. If so, are metabolically healthy obese people at an elevated risk of disease and death?

Does metabolically healthy obesity exist?

Many of you are already aware of the recent study that examined atherosclerosis in 137 ancient mummies from four different cultures (1). Investigators used computed tomography (CT; a form of X-ray) to examine artery calcification in mummies from ancient Egypt, Peru, Puebloans, and arctic Unangan hunter-gatherers. Artery calcification is the accumulation of calcium in the vessel wall, and it is a marker of severe atherosclerosis. Where there is calcification, the artery wall is thickened and extensively damaged. Not surprisingly, this is a risk factor for heart attack. Pockets of calcification are typical as people age.

I'm not going to re-hash the paper in detail because that has been done elsewhere. However, I do want to make a few key points about the study and its interpretation. First, all groups had atherosclerosis to a similar degree, and it increased with advancing age. This suggests that atherosclerosis may be part of the human condition, and not a modern disease. Although it's interesting to have this confirmed in ancient mummies, we already knew this from cardiac autopsy data in a variety of non-industrial cultures (2, 3, 4, 5).
