It's too bad that the article doesn't tell you exactly where to measure your waist. In the old days, they used to tell you to measure around your smallest part, but nowadays, people like Dr. Oz (cardiologist), say to measure right around your belly button. Many people try to measure just below their protruding belly. (You know how some people just slide their belt/pants lower to be able to fit into their "regular" pant size.)
