Wow...I hope the book is better, because I certainly didn't read anything mind-blowing in the article. It all seems very common sense to me--smaller plate=less food, negative emotions=more food (i.e., more popcorn during sad movies), the wine from California vs. North Dakota (I've seen very similar "experiments" performed on Showtime's Penn & Teller's Bullsh!t)...
I'm reading this book now, I'm about 1/3 of the way through, and so far I think it is absolutely fantastic. I'll write up more when I'm done, so I'll have a better overall perspective.
