From the website:
Overeating, the Food Industry, and the Human Brain
Dr. David Kessler says that if a bear comes into a room, humans are wired to respond. But replace that bear with a plate of warm, gooey, chocolate chip cookies and many of us, he says, will become focused on the cookies and will have to eat them. Kessler says the food industry knows this and is constantly coming up with food products that we crave — products that are made of three ingredients: sugar, fat, and salt. Kessler’s new book is “The End of Overeating: Taking Control of the Insatiable American Appetite.”
Chocolate chip cookies are definitely my biggest weakness, I have to say. There's a lot I can say "no thanks" to, but choc chip cookies and very nice chocolate, those are things I have a hard time turning down. Anyway, the whole story was fascinating. If you have a few minutes, tune in and listen. Dr Kessler talk a lot about brain function and over-eating. Very fascinating.
