Over the years, Brian Wansink, director of the Food and Brand Lab at Cornell University, has studied such things as how far Americans typically drive to buy food, how many times we refill our plates at all-you-can-eat buffets and how we organize our kitchens. In the mid-2000s he famously coined the phrase “mindless eating”(and wrote a book by that name) to focus attention on all the bad dietary decisions we make without really thinking about them.
His new book, Slim by Design: Mindless Eating Solutions for Everyday Life, aims to change the design of restaurants, school lunchrooms, office cafeterias and homes so that the mindless choices we make will be more healthful ones. Some examples:
Keep kitchen counters clear. No visible snack food, no bread, no nuts--not even breakfast cereal. In Wansink’s research, “women who had even one box of breakfast cereal that was visible-anywhere in their kitchen--weighed 21 pounds more than their neighbor who didn’t.”
Trick yourself into drinking less wine. “We tend to focus on the height of what we pour and not the width, so we pour 12 percent less wine into taller wineglasses than we pour into wider wineglasses.” And the shape of the glass is not the only variable that affects how much we drink. Wansink writes: “Because red wine is easier to see than white wine, we pour 9 percent less red wine whenever we pour a glass.”
Wansink said his researchers also found that people ate less at restaurants when sat in well-lighted areas near windows and doors, than in darker areas or in the back. They ate less if they were offered a doggie bag, or to-go box, before they got their meals: apparently the idea of getting a “free” second meal outweighed the impulse(冲动) to clean their plates. Workers who frequently ate at their desks weighed 15.4 pounds less, on average, than those who didn’t. Fruits and vegetables kept on the top shelf of the refrigerator were eaten at higher rates than those on lower shelves.
The point, Wansink says, is to consider findings like those and change your environment or habits. Then you won’t have to think about it: You’ll just eat less.
