New research reported in the European Heart Journal on September 4, 2012, reports that a large subset of obese people is in fact healthy. The research was reviewed at the Eureka Alert web site the same day.
The findings hinge on one fact. A person can be obese but be metabolically healthy. Metabolically healthy people do not have the same risk of developing diabetes, heart disease, cancer, and other chronic diseases that obese people that are not metabolically healthy do.
