A decade ago, a Google search for “obesity” returned 217,000 hits. Now it’s 74 million. According to Harriet Brown, science writer and professor of journalism at Syracuse University, we’re more freaked out than ever about how much we weigh and how our bodies look though science tells us that, in many cases, our fears are unfounded. What if we could be satisfied with our bodies the way they are? Harriet Brown tackles these issues in a provocative new book called “Body of Truth: How Science, History and Culture Drive Our Obsession with Weight and What We Can Do about It.”
