Today in The Takeaway's Science segment, we talk about neuroscience. A handful of new studies suggest that in matters of weight loss, will power could lose out to brainpower. The brain, which is an organ designed to seek out calories, could outsmart the tricks we play on it, such as drinking diet soft drinks. Joining The Takeaway to talk about the brains behind our bulk is Jonah Lehrer. He is The Takeaway's science contributor and author of the books "How We Decide" and "Proust Was a Neuroscientist." Todd Zwillich, The Takeaway's Washington Correspondent also joins the conversation to talk about how health policy could be used to encourage better eating habits.
