Can obesity be healthy? And can we tell when it's harmful?

A new study published in Cell Journal has identified an enzyme called heme-oxygenase-1 (it degrades heme, a component of hemoglobin in the body), which may be a significant cause of obesity-related metabolic disease.

All of us know people who are obese, and yet healthy. They may be small in number, but they have none of the signs of metabolic disease (high blood sugar, cholesterol or BP) which affect overweight people so often.

What protects this people? Is there some factor, in addition to obesity, that leads to metabolic disease. The authors of the Cell Study believe this factor could be HO-1.

To know more, read my article in Science Magazine.
