Brian Wansink is a celebrity scientist and the author of the book "Mindless Eating". His research lab has produced hundreds of studies about how our surroundings affect our eating. For example, that we allegedly eat more when served food on bigger plates.
It's interesting stuff and I read his book and found it quite interesting. Unfortunately, lately Wansink and his lab has gotten into trouble. It seems like they have been a bit too interested in finding "cool" scientific findings to present to the media, at any price.
Seemingly, they've been less interested in more mundane things, like making sure their findings are not just made up fantasies.
Maybe obesity is not quite that influenced by "mindless eating", like the size of your plate, your choice of music or the color of your dining room after all.
Maybe it's still more important what you choose to eat. At least that's my guess.
