I gave a talk on obesity yesterday at Montclair State University. The talk was mostly the same as the plenary talk I gave at the SIAM Annual and Life Sciences meeting in 2010, which I summarized here. Science and math writer Barry Cipra also wrote a piece about the talk in SIAM News. I find it amusing that he called me a mathematical obesity expert. I presented the “push hypothesis” for the obesity epidemic in more detail here.
